Every request sent via a Truecaller app that supports Truecaller SDK has a unique identifier. This identifier is bundled into the response for assuring a correlation between a request and a response. If you want you can check this correlation yourself by:
1. You can use your own custom request identifier via the TrueClient with
Note : The customHash must be a base64 URL safe string with a minimum character length of 8 and maximum of 64 characters
ITrueCallback.onSuccesProfileShared(TrueProfile) verify that the previously generated identifier matches the one in TrueProfile.requestNonce.
IMPORTANT: Truecaller SDK already verifies the request-response correlation before forwarding it to the your app.
