Sign In with OTP

This API signs-in a registered user. Once signed in, the user will have access to the custom functionality developed within your portal (for example, loan/education application forms, progress tracking, contact information, etc.).

Before calling this API you must get the OTP data using the Get Sign In OTP API.

In the JSON body –

  • Pass “OTPSigninRequest” as true.
  • In the “OTPSigninData” property, pass the “Code” and “FieldContent” together with the “Otp” (received on the user’s phone) from the response of the Get Sign In OTP API.

The response will return the “LeadId” and an “AuthKey”. The “AuthKey” is a Private Authentication Key used to authenticate the session after a user has signed in to the portal. It is valid for 4 hours.

Note: You must pass the public authentication key you receive from the Get Public Auth Key API response. It must be passed in the API header as Authorization = <Your Auth Key>
