Use the CData ODBC Driver for Postmark in Microsoft Power Query
The CData ODBC Driver for Postmark enables you to link to Postmark data in Microsoft Power Query, ensuring that you see any updates. This article details how to use the ODBC driver to import Postmark data into Microsoft Power Query.
Connect to Postmark 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.
Using API Key Authentication
Postmark uses server API tokens to authenticate requests. Each Postmark server has its own API token, which controls access to messages, bounces, templates, and statistics associated with that server.
To obtain your Server API Token, log in to your Postmark account and navigate to the server you want to connect to. Go to API Tokens under the server settings and copy the token labeled Server API token.
After setting the following connection properties, you are ready to connect:
- AuthScheme: Set this to APIKey.
- APIKey: Set this to your Postmark Server API Token. This value is sent as the X-Postmark-Server-Token header on every request.
Example connection string:
Profile=C:\profiles\Postmark.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your-server-api-token"
Connecting to Postmark
Once the authentication is configured, you can connect to Postmark and query data from any of the available tables such as OutboundMessages, Bounces, and Templates.
Import Postmark Data
Follow the steps below to import Postmark data using standard SQL:
-
From the ribbon in Excel, click Power Query -> From Other Data Sources -> From ODBC.
- Enter the ODBC connection string. Below is a connection string using the default DSN created when you install the driver:
Provider=MSDASQL.1;Persist Security Info=False;DSN=CData API Source
-
Enter the SELECT statement to import data with. For example:
SELECT , FROM Bounces WHERE = ''
Enter credentials, if required, and click Connect. The results of the query are displayed in the Query Editor Preview. You can combine queries from other data sources or refine the data with Power Query formulas. To load the query to the worksheet, click the Close and Load button.
