Getting Permission Denied Error for Application Integration API

[ahitankar]

Hi Team,

I have an integration in Application Integration which has API Trigger. I am trying to hit the Application Integration API so that the Integration can run.
API: https://integrations.googleapis.com/v1/{name=projects/*/locations/*/integrations/*}:execute?name=projects/app-integration/locations/us-central1/integrations/ERP_Integration

Body Parameter: 

{

  "triggerId": "api_trigger/ERP_Integration_API_1"

}

 I have successfully configured OAuth Authorization, obtained the access token, and applied it to access the API. During the OAuth Client ID setup, I have included https://www.googleapis.com/auth/cloud-platform as the authorization scope. Additionally, my user account has been granted "Application Integration Invoker" permission.

However, despite enabling the API, I am encountering the following error:

I have confirmed that the API is enabled. Attached is a screenshot for your reference.

I have attempted to access the API from the Cloud Shell, API Explorer, and Postman, yet encountered the same error across all platforms. Your assistance in resolving this issue would be greatly appreciated.

Aside from Application Integration API, you may check this guide for other APIs needed to be enabled on your project and proceed testing again.

I hope this information is helpful.
