While Implement M2

For Hip initiated flow
i)I hit these api on in mobile app
https://dev.abdm.gov.in/gateway/v0.5/users/auth/fetch-modes
Receive response on HIP_HOST side
​{{HIP_HOST}}/v0.5/users/auth/on-fetch-modes

ii)https://dev.abdm.gov.in/gateway/v0.5/users/auth/init
Receive response on HIP_HOST side
​{{HIP_HOST}}/v0.5​/users​/auth​/on-init

iii)
https://dev.abdm.gov.in/gateway/v0.5/users/auth/confirm
​{{HIP_HOST}}/v0.5​/users​/auth​/on-init received transaction id

for my app side it would ask transactionId how i get this from App because whenever i call app side it will show 202-Accepted should i maintain database or there is another method for that please let me know in postman manually copy transaction id from HIP_Host side while implementaing on project how i get transaction id

Hi
The HIP/HRP should implement the on-fetch-modes API.
The gateway will call this API as a call back for fetch-modes on gateway.
