@Shubham_Kumar Please use only this to complete M1 milestone. These API’s are mandate. For ABHA creation by using Aadhaar number , follow this sequence:

This API : /v0.5/users/auth/on-notify is for Direct Auth. Request you not to use this as this not mandate for private entities. You can follow only above shared sequence and complete M1 milestone.

Hi @IntegrationSupport only theses two use cases are part of M1 milestone ?

because few days back i received a excel with some use cases which had a different use cases scenario please refer to the below screen shots

please help to guide since this is confusing with what is said above and what is present in the excel provided

First two related to QR scan, if you are a hospital or lab you can implement OR scan. and rest from number 3 are ABHA verification test cases related to what we have shared API screenshot above in this thread.

ok so based on different segments of integerators the mandatory part of the milestone changes ?
