Abha address not generating

Hi,
I need to generate an abha address (healthId) during M1 integration, which I am sending to the following API.

​/v1​/registration​/aadhaar​/createHealthIdWithPreVerified
{
“healthId”: “testbykb88”,
“txnId”: “04914687-cdd9-4bce-95c2-1b2dc91b68c9”
}

However, the healthId I receive in response is null, and the same is true for the ABHA card.
Additionally, can we anticipate that a new abha address(healthId) will automatically be established if I perform the sams procedure through all APIs again and submit a different abha address against the same abha Id in above API call? If I have two abha addresses, which one will appear on the Abha Card?

@IntegrationSupport

Thanks

@kaustubh Can you pls share screenshot of postman payload body and response

When I pass a healthId in the payload, it works the first time, but if I wish to create multiple healthIds for a single abha Id after that, it stops working. In the abha Card, only the first healthId is displayed.
We can create multiple healthId against one abhaId right?
If yes then where it is reflecting and which api should I use to see all healthId associated with my abha Id
@IntegrationSupport
Please find SS where I am making a call and after which I am getting succesfull response but healthId as null (Here due to server err its throwing some diff error but otherwise I am getting abhaID succesfull resp)

@kaustubh You can create multiple ABHA address linked to one ABHA ID. The chronology remains same for ABHA creation with the ABHA creation API’s which can be used to create ABHA. For this concerned issue : pls enter complete health ID with @sbx
