@IntegrationSupport
Please provide us access for v3 APIs.
When I am calling : https://dev.abdm.gov.in/hiecm/api/v3/subscription-requests . I am getting response as:
{
“code”: “900908”,
“message”: "Resource forbidden ",
“description”: “User is NOT authorized to access the Resource. API Subscription validation failed.”
}

Please authorize us.

Our “clientId” is “IIITDELHI_334649” , “name”: “IIIT-Delhi” .

Please authorize us ASAP.

Thanks and regards
