To update the default endpoint in your integration of the Braze SDKs please add the following code to your appboy.xml, where sdk.fra-01.braze.eu is your endpoint:

<string translatable="false" name="com_appboy_custom_endpoint">sdk.fra-01.braze.eu</string>

SDK Endpoint configuration via appboy.xml is available starting with Braze Android SDK v2.1.1.
