APIs using app authentication can only be called by apps that have been authorized to call them.
To authorize an app to access multiple APIs, select the APIs, and click Authorize App. Click Select App, select the app you wish to authorize, and click OK. You can grant access to a maximum of 1000 APIs at a time.
If an app does not need to call the API, click Cancel Authorization in the row containing the app to unbind it.
After you authorize an app to call an API, the API can be called using SDKs of different programming languages.
