Connect to MailerSend Data from PowerBuilder via ODBC

The CData ODBC Driver for MailerSend can be used from any platform or development technology that supports ODBC, including PowerBuilder. This article shows how to connect to MailerSend data and execute queries from the Database Painter and controls such as the DataWindow.

Connect to MailerSend as an ODBC Data Source

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

The MailerSend API uses API Key authentication via a Bearer token in the Authorization request header.

Using API Key Authentication

Your MailerSend API token is required to create a connection. To obtain your API token:

1. Log into your MailerSend account at app.mailersend.com.
2. Navigate to Settings > API Tokens in your account dashboard.
3. Click Generate new token, provide a name and select the appropriate permissions.
4. Copy the generated API token.

After obtaining your API token, set the following connection properties:

• AuthScheme: Set this to APIKey.
• APIKey: Set this to your MailerSend API token.

Example connection string:

Profile=C:\profiles\Mailersend.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_api_token';

Create a Profile for the ODBC Driver for MailerSend

Follow the steps below to use the Database Painter tool to create a database profile based on an ODBC DSN (data source name) for MailerSend. In the Database Painter, you can use wizards and the UI to work with MailerSend data.

1. In PowerBuilder, click Tools -> Database Painter.
2. In the Objects window in the Database Painter, right-click the ODBC node and click New Profile.
3. On the Connection tab, enter a name for the profile and select the MailerSend DSN in the Data Source menu. 👁 The ODBC DSN, required to create the Database Profile. (Salesforce is shown.)
   
4. To view and modify a table, right-click a table and then click Edit Data -> Grid.

Using MailerSend Data with PowerBuilder Controls

You can use standard PowerBuilder objects to connect to ODBC data sources and execute queries. The following example shows how to retrieve MailerSend data into a DataWindow. You can add the following code to the open method:

SQLCA.DBMS = "ODBC"
SQLCA.DBParm = "ConnectString='DSN=CData API Source'"
CONNECT USING SQLCA;
dw_activity.SetTransObject(SQLCA);
dw_activity.Retrieve();
