Dear @LeenaJaIN , As you mentioned you have already tested api response
using fdm read service. So there can't be problem in rest API. But when
you created an AuthID input parameter in adaptive form then some rules
can be set by invoking the required service and setting up the correct
output elements. This will prefill your adaptive form elements based on
AuthId entered from rest API. Please go through this article as i found
