Is it possible to send a large push but each message is personalized, e.g. with a name, and the goal is to make only one request to the API instead of 1 request per user
is it possible? If yes, what should I do? I'm using pure cURL (php) so code using that library won't be helpful.
I'm also using the old FCM API.. (https://fcm.googleapis.com/fcm/send)
Thank you so much!
No. Firebase Cloud Messaging does not have a mail merge-like feature. You must send each message individually.
