Remarks

The QBConnector class is a lightweight web server which listens for HTTP requests originating from the QuickBooks Integrator classs. Each request sent to the QBConnector by a QuickBooks Integrator class contains the XML data to be communicated to QuickBooks as well as configuration settings specifying how the connection is to be opened. The QBConnector then communicates with QuickBooks via COM, and returns the QuickBooks response (or an error message) in the HTTP reply.

Using the QBConnector class is easy. Simply set Listening to True, and the class will begin listening for incoming messages on the specified LocalPort. The messages will be processed by the QuickBooks application that is running on the same machine as the QBConnector, and the results will automatically be returned to the requesting client.

Basic authentication is enabled by default, meaning the connecting clients must present a user name and password in the QBConnectionString of the class they're using. The supplied user name and password are checked against the list of AuthorizedUsers. If no user in the list matches the supplied credentials, the Authorization event will fire with the Accept parameter set to false. If the user was found in the list of AuthorizedUsers then the parameter will be set to True. You may override this functionality by setting the Accept parameter inside the Authorization event manually. If no "Authorization" header supplied in the request, the Authorization event will fire with blank User and Password parameters.

Note that the AuthorizedUserQBConnectionString will be used to make the connection to QuickBooks for a user found in the AuthorizedUsers collection.

Any of the QuickBooks Integrator classs can connect to the QBConnector using the QBConnectionString property of any of the classs. For instance, an example using the Invoice class follows: Invoice.QBConnectionString = "URL='http://www.foo.com:2080'" User='Foo' Password='Bar'";

Using SSL along with a digital certificate greatly increases the security of the Remote Connector. SSL will encrypt all data transmitted across the network, ensuring that only the Connector can read incoming requests, and that only the requesting client can read the QuickBooks responses. This prevents unauthorized parties from accessing your QuickBooks data. You should use a full digital certificate on the server (Connector) side, and this will contain a public key and a private key. This version of your certificate should be kept private. You may export a version of the certificate containing the public key only, and distribute this to all clients that need to communicate with the Connector.

To use this functionality, set the SSLCert with a valid certificate and then change the SSLStartMode to sslImplicit. Now all clients must post to the QBConnector using HTTPS. eg: Invoice.QBConnectionString = "URL='https://www.foo.com:2080' User='Foo' Password='Bar'"; // https instead of http

The client (in these examples Invoice) has an SSLServerAuthentication event that will fire when the server presents its certificate. If the public key presented by the QBConnector is trusted by the system, the Accept parameter will be True. If it is not trusted by the system (Accept is False), you should inspect the certificate and if valid, override by setting Accept to True.

LocalHost Property (InQB_QBConnector Class)

The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

Object Oriented Interface


public function getLocalHost();


public function setLocalHost($value);

Procedural Interface


inqb_qbconnector_get($res, 9 );


inqb_qbconnector_set($res, 9, $value );

Default Value

''

Remarks

The LocalHost property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface.

If the class is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multi-homed hosts (machines with more than one IP interface).

NOTE: LocalHost is not persistent. You must always set it in code, and never in the property window.

Data Type

String

LocalPort Property (InQB_QBConnector Class)

The TCP port in the local host where the class listens.

Object Oriented Interface


public function getLocalPort();


public function setLocalPort($value);

Procedural Interface


inqb_qbconnector_get($res, 10 );


inqb_qbconnector_set($res, 10, $value );

Default Value

2080

Remarks

The LocalPort property must be set before QBConnector starts listening. If its value is 0, then the TCP/IP subsystem picks a port number at random. The port number can be found by checking the value of the LocalPort property after Listening is set to True.

The service port is not shared among servers (i.e. there can be only one QBConnector 'listening' on a particular port at one time).

The default value for LocalPort is 2080.

Data Type

Integer

SSLAuthenticateClients Property (InQB_QBConnector Class)

If set to True, the server asks the client(s) for a certificate.

Object Oriented Interface

Remarks

This property is used in conjunction with the SSLClientAuthentication event. Please refer to the documentation of the SSLClientAuthentication event for details.

Data Type

Boolean

SSLCertEncoded Property (InQB_QBConnector Class)

This is the certificate (PEM/base64 encoded).

Object Oriented Interface


public function getSSLCertEncoded();


public function setSSLCertEncoded($value);

Procedural Interface


inqb_qbconnector_get($res, 13 );


inqb_qbconnector_set($res, 13, $value );

Default Value

''

Remarks

This is the certificate (PEM/base64 encoded). This property is used to assign a specific certificate. The SSLCertStore and SSLCertSubject properties also may be used to specify a certificate.

When SSLCertEncoded is set, a search is initiated in the current SSLCertStore for the private key of the certificate. If the key is found, SSLCertSubject is updated to reflect the full subject of the selected certificate; otherwise, SSLCertSubject is set to an empty string.

This property is not available at design time.

Data Type

Binary String

SSLCertStore Property (InQB_QBConnector Class)

This is the name of the certificate store for the client certificate.

Object Oriented Interface


public function getSSLCertStore();


public function setSSLCertStore($value);

Procedural Interface


inqb_qbconnector_get($res, 29 );


inqb_qbconnector_set($res, 29, $value );

Default Value

'MY'

Remarks

This is the name of the certificate store for the client certificate.

The SSLCertStoreType property denotes the type of the certificate store specified by SSLCertStore. If the store is password protected, specify the password in SSLCertStorePassword.

SSLCertStore is used in conjunction with the SSLCertSubject property to specify client certificates. If SSLCertStore has a value, and SSLCertSubject or SSLCertEncoded is set, a search for a certificate is initiated. Please see the SSLCertSubject property for details.

Designations of certificate stores are platform-dependent.

The following are designations of the most common User and Machine certificate stores in Windows:

MYA certificate store holding personal certificates with their associated private keys.
CACertifying authority certificates.
ROOTRoot certificates.

When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e. PKCS12 certificate store).

0

Remarks

This is the type of certificate store for this certificate.

The class supports both public and private keys in a variety of formats. When the cstAuto value is used the class will automatically determine the type. This property can take one of the following values:

0 (cstUser - default)For Windows, this specifies that the certificate store is a certificate store owned by the current user. Note: this store type is not available in Java.
1 (cstMachine)For Windows, this specifies that the certificate store is a machine store. Note: this store type is not available in Java.
2 (cstPFXFile)The certificate store is the name of a PFX (PKCS12) file containing certificates.
3 (cstPFXBlob)The certificate store is a string (binary or base64-encoded) representing a certificate store in PFX (PKCS12) format.
4 (cstJKSFile)The certificate store is the name of a Java Key Store (JKS) file containing certificates. Note: this store type is only available in Java.
5 (cstJKSBlob)The certificate store is a string (binary or base64-encoded) representing a certificate store in Java Key Store (JKS) format. Note: this store type is only available in Java.
6 (cstPEMKeyFile)The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate.
7 (cstPEMKeyBlob)The certificate store is a string (binary or base64-encoded) that contains a private key and an optional certificate.

22 (cstBCFKSBlob)The certificate store is a string (binary or base64-encoded) representing a certificate store in BCFKS (Bouncy Castle FIPS Key Store) format. Note: this store type is only available in Java and .NET.
23 (cstPKCS11)The certificate is present on a physical security key accessible via a PKCS11 interface.

To use a security key the necessary data must first be collected using the CertMgr class. The ListStoreCertificates method may be called after setting CertStoreType to cstPKCS11, CertStorePassword to the PIN, and CertStore to the full path of the PKCS11 dll. The certificate information returned in the CertList event's CertEncoded parameter may be saved for later use.

When using a certificate, pass the previously saved security key information as the SSLCertStore and set SSLCertStorePassword to the PIN.

Code Example: SSH Authentication with Security Key certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);

AddUser Method (InQB_QBConnector Class)

Adds a new user to the AuthorizedUsers collection.

Object Oriented Interface

public function doAddUser($user, $password, $qbconnectionstring, $authmode);

Procedural Interface

inqb_qbconnector_do_adduser($res, $user, $password, $qbconnectionstring, $authmode);

Remarks

Please refer to the AuthorizedUsers collection for more information.

User specifies the user which will be allowed to connect.

Password specifies the password of the user. This is not applicable when AuthMode is set to 1 (amWindows).

QBConnectionString sets the connection properties for the user. See AuthorizedUserQBConnectionString for details.

AuthMode defines how the user will be authenticated. There are two ways that the user may be authorized, against the user list defined in the class, or as a Windows user. From the client side the process of connecting is exactly the same no matter which option you choose. Possible values are:

0 (amNormal - default) The user is authenticated against the user list defined in the class.
1 (amWindows) The user is authenticated as a Windows user.

When using the amNormal AuthMode (default) the user's password will be checked against the Password property.

When using the amWindows AuthMode the class will validate the user's credentials with Windows. When calling AddUser the Password parameter should be set to empty string.

Config Method (InQB_QBConnector Class)

Sets or retrieves a configuration setting.

Object Oriented Interface

public function doConfig($configurationstring);

Procedural Interface

inqb_qbconnector_do_config($res, $configurationstring);

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

DoEvents Method (InQB_QBConnector Class)

Processes events from the internal message queue.

Object Oriented Interface

public function doEvents();

Procedural Interface

inqb_qbconnector_do_doevents($res);

Remarks

When DoEvents is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns.

Reset Method (InQB_QBConnector Class)

Clears all properties to their default values.

Object Oriented Interface

public function doReset();

Procedural Interface

inqb_qbconnector_do_reset($res);

Remarks

This method clears all properties to their default values.

Shutdown Method (InQB_QBConnector Class)

Shutdown the server.

Object Oriented Interface

public function doShutdown();

Procedural Interface

inqb_qbconnector_do_shutdown($res);

Remarks

When this method is called, the class will stop Listening, break all active connections, and disconnect from QuickBooks.

Authorization Event (InQB_QBConnector Class)

Fired when the client presents its credentials to the server.

Object Oriented Interface

public function fireAuthorization($param);

Procedural Interface

inqb_qbconnector_register_callback($res, 1, array($this, 'fireAuthorization'));

Parameter List

 'connectionid'
'userindex'
'user'
'password'
'accept'

Remarks

This is where the server can decide whether to continue or not, based on the supplied User and Password.

To accept or reject a connection set Accept to True of False.

The Accept parameter defaults to True if User is found in the AuthorizedUsers collection and Password matches, and False otherwise. The UserIndex parameter indicates the index at which the authorized user was found in the collection.

A UserIndex of -1 means that no matching credentials were found in the AuthorizedUsers collection.

Connected Event (InQB_QBConnector Class)

This event is fired immediately after a connection completes (or fails).

Object Oriented Interface

public function fireConnected($param);

Procedural Interface

inqb_qbconnector_register_callback($res, 2, array($this, 'fireConnected'));

Parameter List

 'connectionid'
'statuscode'
'description'

Remarks

This event allows the class to be configured to use both RSA and ECDSA certificates depending on the connecting client's capabilities.

ConnectionId is the connection Id of the client requesting the connection.

SupportedCipherSuites is a comma-separated list of cipher suites that the client supports.

SupportedSignatureAlgs is a comma-separated list of certificate signature algorithms that the client supports.

CertStoreType is the store type of the alternate certificate to use for this connection. The class supports both public and private keys in a variety of formats. When the cstAuto value is used the class will automatically determine the type. This property can take one of the following values:

0 (cstUser - default)For Windows, this specifies that the certificate store is a certificate store owned by the current user. Note: this store type is not available in Java.
1 (cstMachine)For Windows, this specifies that the certificate store is a machine store. Note: this store type is not available in Java.
2 (cstPFXFile)The certificate store is the name of a PFX (PKCS12) file containing certificates.
3 (cstPFXBlob)The certificate store is a string (binary or base64-encoded) representing a certificate store in PFX (PKCS12) format.
4 (cstJKSFile)The certificate store is the name of a Java Key Store (JKS) file containing certificates. Note: this store type is only available in Java.
5 (cstJKSBlob)The certificate store is a string (binary or base64-encoded) representing a certificate store in Java Key Store (JKS) format. Note: this store type is only available in Java.
6 (cstPEMKeyFile)The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate.
7 (cstPEMKeyBlob)The certificate store is a string (binary or base64-encoded) that contains a private key and an optional certificate.
8 (cstPublicKeyFile)The certificate store is the name of a file that contains a PEM- or DER-encoded public key certificate.
9 (cstPublicKeyBlob)The certificate store is a string (binary or base64-encoded) that contains a PEM- or DER-encoded public key certificate.
10 (cstSSHPublicKeyBlob)The certificate store is a string (binary or base64-encoded) that contains an SSH-style public key.
11 (cstP7BFile)The certificate store is the name of a PKCS7 file containing certificates.
12 (cstP7BBlob)The certificate store is a string (binary) representing a certificate store in PKCS7 format.
13 (cstSSHPublicKeyFile)The certificate store is the name of a file that contains an SSH-style public key.
14 (cstPPKFile)The certificate store is the name of a file that contains a PPK (PuTTY Private Key).
15 (cstPPKBlob)The certificate store is a string (binary) that contains a PPK (PuTTY Private Key).
16 (cstXMLFile)The certificate store is the name of a file that contains a certificate in XML format.
17 (cstXMLBlob)The certificate store is a string that contains a certificate in XML format.
18 (cstJWKFile)The certificate store is the name of a file that contains a JWK (JSON Web Key).
19 (cstJWKBlob)The certificate store is a string that contains a JWK (JSON Web Key).
21 (cstBCFKSFile)The certificate store is the name of a file that contains a BCFKS (Bouncy Castle FIPS Key Store). Note: this store type is only available in Java and .NET.
22 (cstBCFKSBlob)The certificate store is a string (binary or base64-encoded) representing a certificate store in BCFKS (Bouncy Castle FIPS Key Store) format. Note: this store type is only available in Java and .NET.
23 (cstPKCS11)The certificate is present on a physical security key accessible via a PKCS11 interface.

To use a security key the necessary data must first be collected using the CertMgr class. The ListStoreCertificates method may be called after setting CertStoreType to cstPKCS11, CertStorePassword to the PIN, and CertStore to the full path of the PKCS11 dll. The certificate information returned in the CertList event's CertEncoded parameter may be saved for later use.

When using a certificate, pass the previously saved security key information as the and set to the PIN.

Code Example: SSH Authentication with Security Key certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);

99 (cstAuto)The store type is automatically detected from the input data. This setting may be used with both public and private keys and can detect any of the supported formats automatically.

CertStore is the store name or location of the alternate certificate to use for this connection.

Designations of certificate stores are platform-dependent.

The following are designations of the most common User and Machine certificate stores in Windows:

MYA certificate store holding personal certificates with their associated private keys.
CACertifying authority certificates.
ROOTRoot certificates.

When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e. PKCS12 certificate store).

CertPassword is the password of the certificate store containing the alternate certificate to use for this connection.

CertSubject is the subject of the alternate certificate to use for this connection.

The special value * matches any subject and will select the first certificate in the store. The certificate subject is a comma separated list of distinguished name fields and values. For instance "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are displayed below.

FieldMeaning
CNCommon Name. This is commonly a host name like www.server.com.
OOrganization
OUOrganizational Unit
LLocality
SState
CCountry
EEmail Address

If a field value contains a comma it must be quoted.

Config Settings (QBConnector Class)

The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

QBConnector Config Settings

AuthFlags:   Auth Flags to use when connecting to QuickBooks.

This configuration setting controls what auth flags are sent to QuickBooks. The default value is 0 (no auth flags set).

ConnectedToQB:   Used to connect or disconnect from QuickBooks.

This setting allows you to connect and disconnect to the QuickBooks request processor which resides on the server machine. Calling Config with ConnectedToQB=False will immediately disconnect from QuickBooks. ConnectedToQB=True, however, will use the DefaultConnectionString (if present) to open a persistent connection to QuickBooks. Note that if the class is already connected to QuickBooks, setting ConnectedToQB to True will cause the class to fails with an error. Connecting in this manner is only useful if there are no connection strings specified in any AuthorizedUsers, as in that case the class will disconnect from QuickBooks and reconnect with the credentials specified for that individual user. However, it is not necessary to use this configuration setting to connect to QuickBooks. If no connection strings are specified in the AuthorizedUsers and the class is not currently connected to QuickBooks, a new connection will be made using the DefaultConnectionString.

DefaultConnectionString:   Default connection string to use for users not in the AuthorizedUsers collection.

If a user connects to the class who is not in the AuthorizedUsers collection, and you set the Accept parameter in the Authorization event to True anyways, the class will use this connection string to open a connection with QuickBooks. This is blank by default.

ReadOnly[i]:   Whether a user is restricted to read-only access.

This setting specifies whether a user is limited to read-only access. The index should be the of the user in the AuthorizedUsers collection. For instance: QBConnector1.Config("ReadOnly[0]=True"); This indicates that the first user is limited to read-only access. The default value is False (full access).

UseInteractiveLogon:   Whether interactive or network logon is used when AuthMode is set to Windows.

This setting only applies when the AuthorizedAuthMode is set to 1 (amWindows). When performing windows authentication a regular network logon is attempted by default. When this setting is set to true an interactive logon is performed instead. This setting may be required in certain circumstances, such as using a domain account and the domain controller is Samba.

Base Config Settings

BuildInfo:   Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

CodePage:   The system code page used for Unicode to Multibyte translations.

The default code page is Unicode UTF-8 (65001).

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a class is using. It will return the following information:

  • Product: The product the license is for.
  • Product Key: The key the license was generated from.
  • License Source: Where the license was found (e.g., RuntimeLicense, License File).
  • License Type: The type of license installed (e.g., Royalty Free, Single Server).
  • Last Valid Build: The last valid build number for which the license will work.
MaskSensitive:   Whether sensitive data is masked in log messages.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to true to mask sensitive data. The default is true.

This setting only works on these classes: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

ProcessIdleEvents:   Whether the class uses its internal event loop to process events when the main thread is idle.

If set to False, the class will not fire internal idle events. Set this to False to use the class in a background thread on Mac OS. By default, this setting is True.

SelectWaitMillis:   The length of time in milliseconds the class will wait when DoEvents is called if there are no events to process.

If there are no events to process when DoEvents is called, the class will wait for the amount of time specified here before returning. The default value is 20.

UseInternalSecurityAPI:   Tells the class whether or not to use the system security libraries or an internal implementation.

When set to false, the class will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this setting to true tells the class to use the internal implementation instead of using the system security libraries.

On Windows, this setting is set to false by default. On Linux/macOS, this setting is set to true by default.

To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the OpenSSL Notes section.
