Module Used: Firebase Module
I have followed all the steps given in this link
Able to get the access token and registration token in mendix debugger mode, when i send a message to a particular topic.
But the problem is, i receive the error status code ‘INVALIDARGUMENT’ ie. Registration token is not valid FCM registration token when FCM POST method is invoked in microflow.
But it works fine when i try it firebase console but not working via mendix implementation.
How to overcome this issue? To receive the push notifications in android device.
Please find the response i got in postman when i tried to access the FCM API
