How to Fix DisallowedResourceOperation When Retrieving Power Apps by Environment API
Question details
The user needs to retrieve a list of Power Apps separated by environment via an API but encounters an operation error.

- Product
- Power Apps / Azure Management API
- Device & OS
- not provided
- Scenario
- Attempting to list Power Apps within specific environments using the Azure Management API.
- Observed behavior
- The API request fails and returns a DisallowedResourceOperation error because the environments/apps resource operation is not supported through the current endpoint or API version.
Ensure you have the necessary administrative privileges and the correct Tenant ID for your Power Platform environment before testing API calls.
Verify and Use the Supported Power Platform Administration APIs
The Azure Management API endpoint may not support listing Power Apps directly. Switch to the official Power Platform APIs.
The DisallowedResourceOperation error specifically indicates that the URL or the HTTP method you are calling is not recognized for that resource. Microsoft maintains dedicated administration endpoints for Power Platform.
Navigate to the official Microsoft Power Platform API documentation to find the dedicated endpoints for environment and app management.
Ensure your API request targets the correct Power Platform admin endpoint rather than the generic Azure Management API. Check that your API version parameter matches the latest supported version.
Ensure the service principal or account making the request has the required administrative permissions, such as the Power Platform Administrator role.
Request Assistance on Microsoft Q&A
If the correct endpoint remains unclear or the error persists, seek help from Microsoft API experts.

Frequently Asked Questions
Why am I getting a DisallowedResourceOperation error in Azure API?
This error typically occurs when the specific resource operation (like environments/apps) is not supported through the Azure Management API endpoint or the API version you are currently trying to use.
What permissions do I need to list Power Apps by environment?
You generally need administrative privileges, such as Power Platform Administrator or Environment Admin roles, depending on the scope of the apps you are trying to retrieve.
Where can I find the correct API endpoint for Power Apps?
The correct endpoints are documented in the Microsoft Power Platform API reference guide. Using dedicated Power Platform management APIs instead of general Azure management endpoints is highly recommended to avoid routing errors.
