Declare Firebase Notification TTL on python PyFCM

Question

This code is working as expected, but all the notifications sent are set default expiry time (28 days).

from pyfcm import FCMNotification
push_service = FCMNotification(api_key="<api-key>")
data_message = {"foo":"bar"}
result = push_service.notify_single_device(registration_id=registration_id, data_message=data_message)

How can I set the expire time to less than default so very old notifications dont make their way to the users devices?

Answer 1

Taking a look at the PyFCM documentation on GitHub I could find the solution:

time_to_live (int, optional): How long (in seconds) the message should be kept in FCM storage if the device is offline. The maximum time to live supported is 4 weeks. Defaults to None which uses the FCM default of 4 weeks.

Example implementation to set notification to expire after 1 hour if not delivered:

push_service.notify_single_device(registration_id=registration_id, data_message=data_message, time_to_live=3600)
