Overriding API addresses of push services for testing

The configuration is done in the main.json configuration file.

The platform can send push messages to the following services:

• APNs (Safari)
• APNs (iOS)
• Firebase
• Mozilla Firefox
• Appmetrica
• HMS

You can override the API address for each of them using the ACCOUNT_OVERRIDES field. For the Firebase service, it is possible to specify a test address both for the legacy API (FIREBASE_LEGACY_CUSTOM_SENDING_URL) and for API v1 (FIREBASE_APIv1_CUSTOM_SENDING_URL).
