Power Automate "Wait for an Approval" Not Resuming After Delayed Approval Response

(0) Share

Report

Posted on by CU08061146-1

When an approver responds through Microsoft Teams, the flow resumes almost immediately and continues processing.

However, in our application, we update the approver's response (Approve/Reject) in a Dataverse table through an API. Although the response record is created successfully in Dataverse, the flow remains stuck at the Wait for an Approval action for a significant amount of time before eventually resuming and completing.

Is there a way to achieve the same near real-time behavior as a Teams approval response, so that the flow continues immediately when the approval status is updated through the API/Dataverse instead of waiting for the approval action to resume?

Hi @CU08061146-1

This  is a fundamental architectural limitation, not a configuration error.

Teams/Email Approvals (Immediate): Event-Driven

Dataverse Direct Writes (Delayed): Passive Polling

Instead of writing to Dataverse tables, call the official Approvals API from your external application:

          https://api.flow.microsoft.com/providers/Microsoft.ProcessSimple/environments/<environment>/approvals/<id>/approvalResponses



Body: {
"properties": {
"response": "Approve",
"comments": "Comment"
}
}





This is also almost real time.

Let me know if it worked!

How do we integrate this api directly in our application, and what are the headers and how do we authenticate it.

Hi

What application is it? PowerApp? Web App?

Which account is used for the approval? The loggin user or a service account?

Hi @chiaraalina,

It's the Web App, we are using the service account.

Hi @CU08061146-1

If it is a service account I suggest this:

Schema example:

{

"type": "object",

"properties": {

"approvalId": {

"type": "string"

},

"response": {

"type": "string"

},

"comment": {

"type": "string"

}

}

}

Also secure the first step:

Generate a secret for example Secret123 (choose better), so the flow will only trigger if the secret is correct.

Then do the request like described in my previous answer, but pass the input variables

Response is "Approve" if you want to approve.

Use your service account for the connection for the Approve (Invoke HTTP request action - described in the previous comment) step and make sure your service account is allowed to approve the approval.

Save it and then use the generated HTTP URL to send Post request from your Web App.

Let me know if it worked!
