Hi Gopu,
The return result you provided appears to be the list of access requests from this API:
i.e.:
https://{{orgname}}.api.identitynow.com/beta/access-request-status
This won’t help you. In order to approve the access request, you need to find the approval record, which you can get from this API:
i.e.:
https://{{orgname}}.api.identitynow.com/beta/access-request-approvals/pending
Then you can use the id returned in this object to pass into the access-request-approvals/{{approvalId}}/approve API
