Error sending FCM message

[Ori Idan]

Hello,

I am trying to use the new API for FCM (the legacy API works fine now).

I get the following error:

Invalid JSON payload received. Unknown name \"to\": Cannot find field.\nInvalid JSON payload received. Unknown name \"data\": Cannot find field.

The JSON payload is:

{"to":"1234","data":{"message":"This is an FCM notification message!"}}

Where 1234 is replaced with the actual registration id.

Hi, Ori:

The payload format is a little different in the v1 API, check out the new format here:

Thank you for your answer.

I see that the registration number of my client is given in the token field so for simple notifications I don't need to to and data field.

How do I send the same message to several registration numbers (I want to send the message to all devices owned by same user) do I have to send in a loop or is there a better method?

Also my current payload includes the following fields: message, title, type (number used by my app), param (url in case of a notification containing url) how can I sent this data?
