Awesome! You’ve completed the client-side integration. Now, after the OTP is verified, you’ll get a callback with the ONETAP response containing the token. You’ll need to parse the token from the response JSON.

Sample Callback JSON

  "responseType": "ONETAP",
  "statusCode": 200,
  "response": {
    "status": "SUCCESS",
    "token": "unique_token_here",
    "userId": "unique_user_id_here",
    "timestamp": "ISO_timestamp_here",

        "channel": "OTP",
        "methods": [
          "SMS"
        ],
        "verified": true,
        "verifiedAt": "2024-08-05T13:57:56Z"
      }
    ],
    "idToken": "jwt_token",
    "network": {
      "ip": "127.0.0.1",
      "timezone": "Asia/Kolkata",
