Azure Role Assignment Approval On PIM Resources

currently I'm trying to create and approve requests for the Privileged Identity Management in Azure.

Both of these are working fine over the Azure Portal and I wanted to do the same with the from Microsoft provided APIs.
Creating these requests is no problem, but I am not able to approve the created requests. The requests are for Azure Resources (not AD Roles, these are working).
Here my attempts:

  1. Graph API

Create Request:
Update/Approve Request:

In here there is one thing that confuses me, the status "PendingAdminDecision". When I create my requests inside of the Azure Portal and through the Graph API the status is always "PendingApproval". With this status I can get all the open requests that are not yet approved. The status "PendingAdminDecision" described in the Graph API is nowhere found. When I try to approve one of my open requests (in status "PendingApproval"), I get the message "The role assignment request has already been approved or denied". Either from Graph Explorer, C# Code or PowerShell.

  1. Azure REST API - Authorization

Here I can find my pending approval by listing all Role Assignment Approvals (
With the gathered information I wanted to approve my request ( or PUT

Sadly it does not work here either. I tried the "Try It" functionality and I gave it a try via Postman.
The only thing that I get back is: Response Code 500 - Internal Server Error --> Message - An error has occurred


Can you provide any suggestions for this problem?
I checked my AD Roles for this account.

Best regards
