I'm trying Firebase-Notification API the service is worked perfect when i send downstream message from console to app, but how to send message to topic registered users ?
i did in android side
This project does not have any topics
First You need to create topic thorugh making POST request on
IID_TOKEN -> WITH REGISTERATION TOKEN TOPIC_NAME -> WITH TOPIC-NAME YOU WANT CREATE
And to check your created Topics make a GET request on this URL
and insert your API_KEY in your Request HEADERS
and your topic will take up to 1 day to show up in firebase console so for testing you can make curl request or use a sofware like Advanced REST client
