Generating Client ID

PreviousIntegration StepsNextSetup

Last updated 11 months ago

To ensure the authenticity of interactions between your app and Truecaller, you need to generate a client ID from the Truecaller developer portal by following the steps below:

  • Go to and register your account.

  • Once registered, log in to your account and click on the "create project” button.

  • Enter the project name and select the business category from the dropdown menu. This will create a new project.

  • On the project screen, click the “add credential” button and select the platform as Android from the dropdown menu.

  • On the credential section, enter the package name and the SHA1.

  • Your package name corresponds to the applicationId in your app level build.gradle file.

You can get to know the SHA1 for your different app builds by following these steps :

  • Open your project in android studio

  • Open terminal

  • Type command ./gradlew signingReport

Once done you should be able to see the SHA1 fingerprint of your different build configurations [ debug /release ] in the terminal window within the android studio.

Once you input your app details and create the app, you will be able to see a unique "ClientID" for your app which you need to include in your project to authorise all verification requests.
