Setting up the DocumentsCorePack Custom Connector for Power Automate

1119 views 1 Updated on November 2, 2026

In this article, we will show you how to create a DocumentsCorePack custom connector for PowerAutomate enabling users to utilize the document generation and processing capabilities within their Flows and Canvas Apps.

Important: The method described here is already outdated and is only useful for manually importing the DocumentsCorePack REST-API. We highly recommend using the certified DocumentsCorePack connector. Please go to following article to learn how you can set up the certified connector.

Prerequisites:

  • Your DocumentsCorePack service must be hosted on mscrm-addons.com (Open Service Configuration)
  • Your DocumentsCorePack service must use Server2Server authentication

​Step-by-Step guide:

1. Visit https://documentapi.mscrm-addons.com/swagger/v1/swagger.json and save the JSON file locally.

6. After creating the connector, you will need to get an API key to use it. To get an API key, visit the DocumentsCorePack Online Service Configuration, select your service and navigate to the Connector tab. Click on the Create Key button to generate an API key.

Note: The API key will only be displayed once. Make sure to copy the key before proceeding. Otherwise, you will have to revoke the key and create a new one.

7. When attempting to add an action from the connector to a flow, you will be prompted to enter a name and API key. Enter the value from step 6 here. Once the key has been entered, you will able to use the custom connector for your flows.
