}Initiate SIM Binding POST
Initiates the SIM binding process to link a users mobile SIM with their device for UPI authentication. This is Step 1 of the sequential SIM binding flow. After receiving a successful response, the client app must send an SMS with the returned data payload to the VMN number specified in result.to. SIM binding is required on first-time registration, device change, or app reinstallation. VMN (Virtual Mobile Number) must be pre-configured by M2P based on VMNs provided by the client during onboarding.
Check Transaction Status Response POST
Fetches the result of a previously initiated transaction status check. Pass the callbackRef from checkTxnReq. Returns the definitive transaction status from NPCI including RRN, response code, amount, and timestamps.
