Truecaller has launched an SDK called TrueSDK, that will let app developers verify users via their phone numbers and login using their Truecaller profiles. The SDK, which will also enable developers to update a user’s information, has launched with 12 partners including CarDekho, Quikr, OYO Rooms and ixigo. As of now the SDK is Android only and is available to registered third party apps. Truecaller mentions that the SDK will require user permission before verifying their identities. The SDK is free for developers to use.
