Response

{
  "statusCode": 200,
  "success": true,
  "response": {
    "channel": "OAuth",
    "channelType": "WHATSAPP",
    "requestId": "xxxxxxxxxxxxxxxx"
  }
}

Step 2: Get Auth Token

Awesome! You’ve completed the client-side integration. Now, after the User identity is verified with social platform, 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",
    "identities": [
      {
        "identityType": "MOBILE",
        "identityValue": "919899038845",
        "channel": "WHATSAPP",
        "methods": [
          "WHATSAPP"
        ],
        "name": "Satyam Nathani",
        "verified": true,
        "verifiedAt": "2024-08-05T14:02:57Z"
      }
    ],
    "idToken": "jwt_token",
    "network": {
      "ip": "127.0.0.1",
      "timezone": "Asia/Kolkata",
      "ipLocation": {}
    },
    "deviceInfo":{},
    "sessionInfo":{},
    "firebaseInfo":{}
  }
}

How to parse the token from response?

private void onHeadlessCallback(HeadlessResponse response) {
    if (response.getStatusCode() == 200) {
        switch (response.getResponseType()) {
            case "ONETAP":
                // final response with token
                JSONObject responseWithToken = response.getResponse();
                // Your API to send the token to your backend and then follow the next step.
                break;
            // other response types
        }
        JSONObject successResponse = response.getResponse();
    } else {
        // handle error
        String error = response.getResponse().optString("errorMessage");
    }
}

🏁 Check Point : Verify Auth Token

Once you have retrieved the token, send it to your backend and call the verify token API.
