How to Connect to & Open Postmark Data in Microsoft Excel

The CData ODBC driver for Postmark uses the standard ODBC interface to link Postmark data with applications like Microsoft Access and Excel. Follow the steps below to use Microsoft Query to import Postmark data into a spreadsheet and provide values to a parameterized query from cells in a spreadsheet.

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.

You can then work with live Postmark data in Excel.

NOTE: In recent versions of Excel, Microsoft Query is not visible by default. To enable visibility, Navigate to Options > Data and check From Microsoft Query (Legacy) under the Show legacy data import wizards section.

1. In Excel, open the Data tab and choose Get Data -> Legacy Wizards -> From Microsoft Query (Legacy).
2. Choose the API DSN. Select the option to use Query Wizard to create/edit queries.
3. In the Query Wizard, expand the node for the table you would like to import into your spreadsheet. Select the columns you want to import and click the arrow to add them to your query. Alternatively, select the table name to add all columns for that table.
4. The Filter Data page allows you to specify criteria. For example, you can limit results by setting a date range.
5. If you want to use parameters in your query, select the option to edit the query in Microsoft Query.

6. To set a parameter in the query, you will need to modify the SQL statement directly. To do this, click the SQL button in the Query Editor. If you set filter criteria earlier, you should have a WHERE clause already in the query.

   To use a parameter, use a "?" character as the wildcard character for a field's value in the WHERE clause. For example, if you are importing the Bounces, you can set "=?".

7. Close the SQL dialog when you are finished editing the SQL statement. You will be prompted to enter a parameter value. In the next step, you will select a cell to provide this value. So, leave the box in the dialog blank.

8. Click File -> Return Data to Microsoft Excel. The Import Data dialog is displayed. Enter a cell where results should be imported.

9. Close the Import Data dialog. You will be prompted to enter a parameter value. Click the button next to the parameter box to select a cell. Select the option to automatically refresh the spreadsheet when the value changes.

The data is now imported into Excel. When you change the value in cell B1, the data will be filtered by the specified search criteria.
