You can use SharePoint events, such as adding new files to—or updating existing files within—SharePoint document libraries, to automatically run Unstructured ETL+ workflows that rely on those document libraries as sources. This enables a no-touch approach to having Unstructured automatically process new and updated files in SharePoint document libraries as they are added or updated. This example shows how to automate this process by adding a custom Power Automate flow to your Microsoft 365 or Office 365 account. This flow runs whenever a new or updated file is detected in the specified SharePoint document library. This flow then calls the Unstructured Workflow Endpoint to automatically run the specified corresponding Unstructured ETL+ workflow within your Unstructured account.
This example uses a custom Power Automate flow that you create and maintain. Any issues with file detection, timing, or flow invocation could be related to your custom flow, rather than with Unstructured. If you are getting unexpected or no results, be sure to check your custom flow’s run history first for any informational and error messages.

Step 3: Create a Power Automate flow

  1. Sign in to Power Automate.
  2. On the sidebar, click Create.
  3. In the Start from blank area, click Automated cloud flow.
  4. Enter some Flow name for your new flow.
  5. For Search all triggers, enter When a file is created or modified (properties only), and then click When a file is created or modified (properties only) (SharePoint).

  5. After the job status shows Finished, go to your destination location to see the results.

​
Step 5 (Optional): Turn off the flow

To stop the Power Automate flow from running automatically, go back to the web browser tab from earlier in Step 3. Then, with the flow’s home page still open, in the top navigation bar, click the power (Turn off) button to change it to Turn on (which means that the flow is off and inactive).
