To retrieve data for mobile apps via API, you need to provide the app ID. There are a few ways to do this.

  1. Using the App ID endpoint in the API. This endpoint returns the app IDs related to a requested app.

  2. Via the Apple/Google Play stores. To find them, visit the apps’ page in the app store and extract the ID from the URL. For example,

    • For Android, extract ‘com.whatsapp’ from the URL:

    • For Apple, extract ‘310633997’ from the URL:

  3. Via the URL of the apps’ page on the Similarweb platform. Please omit the 0_/1_ prefix.

    For example, extract ‘com.whatsapp’ from the URL:


Some Android app IDs contain capital letters. Please ensure the correct case is inputted, as they are case-sensitive.

If you have a list of websites and would like to retrieve the app IDs related to them you can use the Site Related Apps API endpoint.
