How do I a configuration of a notification with REST, method GET

Configuration
1

I want every 15 minutes the value of a sensor export to an external website.
That external website (like pvouput.org) can be called as follows:
http://192.168.178.31/upload/data.php?object_id=5970&api_key=123456789abcd&var=ehh&moment=1605862431&value=24168.7

where object_id and api_key are identifiers given by the site
var is the code of the variable where the data must go
moment is the time in utc-integer
value is the state
Therefore I have defined a notification:

notify:
  - name: upload_emo
    platform: rest
    resource: "http://192.168.178.31/upload/data.php?object_id=5970&api_key=123456789abcd"
    method: GET

and an automation:

automation:
  - alias: upload_data_to_emo
    initial_state: 'on'
    trigger:
      - platform: time_pattern
        minutes: "/15"
    action:
      - service: notify.upload_emo
        data_template:
          message: "Test upload"
          moment: "{{ now().timestamp() | int }}"
          var: "eh"
          value: "{{ states.sensor.luxtronik_energieverbruik.state }}¨

But when I run the configuration I get a error message in the log:
“voluptuous.error.MultipleInvalid: extra keys not allowed @ data[‘moment’]”

What am I doing wrong?
Thank you in advance.

I’ve never used it but from looking at the docs I think you have to supply a dictionary of the extra parameters you want to send in the notification options: https://www.home-assistant.io/integrations/notify.rest/#data

notify:
  - name: upload_emo
    platform: rest
    resource: "http://192.168.178.31/upload/data.php?object_id=5970&api_key=123456789abcd"
    method: GET
    data:
      message:
      moment:
      var:
      value:

Also if you are running version 0.115 or greater you should use just data: instead of data_template: in your automation.

I changed my configuration as you suggested:

notify:
  - name: upload_emo
    platform: rest
    resource: "http://192.168.178.31/upload/data.php?object_id=5970&api_key=123456789abcd"
    method: GET
    data:
      message:
      moment:
      var:
      value:    

automation:
  - alias: upload_data_to_emo
    initial_state: 'on'
    trigger:
      - platform: time_pattern
        minutes: "/15"   
        
    action:
      - service: notify.upload_emo
        data: 
          message: "Upload test"
          moment: "{{ now().timestamp() | int }}"
          var: "eh"
          value: "{{states.luxtronik_energieverbruik.state}}"

I still get the same error:
voluptuous.error.MultipleInvalid: extra keys not allowed @ data['moment']

As I said:

So not really sure, just gave it my best guess.
