FCMAdapter initialization

Parameters

• key: dict - Google key. You can get it from the Firebase Console. Documentation here.
• client: Union[httpx.AsyncClient, None] = None - httpx.AsyncClient instance. If not provided, a new instance will be created.
• send_message_url: Union[str, None] = None - FCM send message url. If not provided, the default value will be used.
• validate_only: bool = False - Flag for testing the request without actually delivering the message. Works only with the send_message method.

send

Send a message to a device. See FCM documentation for more details.

Parameters

• data: dict - Data to send to FCM service.

Returns

• Response from FCM service. See FCM documentation for more details.

Example

from fcm_adapter import FCMAdapter


async def main(fcm_adapter: FCMAdapter, token: str):
    response = await fcm_adapter.send(
        {
            "validate_only": False,
            "message": {
                "token": token,
                "notification": {"title": "Hello World"},
            },
        }
    )

send_message

Send a message to a device. The function is a wrapper around the send method, but it expects to receive only inner message data.

If fcm_adapter.validate_only is set to True, the request to FCM will be sent with "validate_only": true.

Parameters

• message: dict - Message data to send to FCM service.

Returns

• Response from FCM service. See FCM documentation for more details.

Example

from fcm_adapter import FCMAdapter


async def main(fcm_adapter: FCMAdapter, token: str):
    response = await fcm_adapter.send_message(
        {
            "token": token,
            "notification": {"title": "Hello World"},
        }
