Obtain the access token by using the following API: https://dev.abdm.gov.in/gateway/v0.5/sessions.
Then, after acquiring the access token, proceeded to call the following API for registering the PHR ID: https://dev.abdm.gov.in/gateway/v1/bridges/addUpdateServices.
I have thoroughly reviewed my request and the API documentation, but I am unable to determine the cause of this error. It appears to be an “Unknown error,” and I would appreciate your assistance in resolving this issue.
