Hello Lalitha, HTTP 202 only means ISC accepted the request and created an async task. It does not confirm that the account was actually enabled. The first thing I would try is sending an empty JSON body:
{}
For this test, remove both externalVerificationId and forceProvisioning.
There is also a similar community case where the API returned a task ID but the account did not change, and using an empty body resolved it.
If it still does not work, check the returned task/account activity and compare it with the activity generated when enabling the same account from the ISC UI.
