Step-by-Step Guide: Creating Custom Connectors with Postman in PowerApps

1. Define API Endpoints:

  • Use Postman to define and test API endpoints that you want to connect to in PowerApps. Ensure that the APIs are well-documented and accessible.

2. Export Postman Collection:

  • Export the Postman collection that includes the defined API endpoints. This collection will serve as the blueprint for the custom connector.

3. Access PowerApps Custom Connectors:

  • Log in to PowerApps, and navigate to the custom connectors section. Click on “New custom connector” to start the creation process.

4. Import Postman Collection:

  • Import the exported Postman collection into PowerApps. PowerApps will use this collection to generate the initial structure of the custom connector.

5. Configure Connection and Authentication:

  • Configure the connection details, authentication methods, and any required parameters for the custom connector to interact with the APIs.

6. Define Actions and Triggers:

  • Define actions and triggers within the custom connector to specify the operations that the app can perform using the connected APIs.

7. Test and Verify:

  • Test the custom connector within PowerApps to ensure that the defined actions and triggers work as expected. Address any issues or fine-tune configurations if necessary.

8. Publish and Share:

  • Once satisfied with the custom connector, publish it to make it available for use in your PowerApps. Share the connector with other app creators if needed.
