Update my Home Zone from Webhook JSON data

Configuration
1

I am struggling to update my zone location using a webhook; could someone help me figure this out ?

this is for an RV so my HOME is changing all the time

here is an example of webhook:

JSON_DATA='{
  "latitude": redacted,
  "longitude": 2.3522
}'

# Send the JSON data to the GPS API
curl -X POST \
  -k -H "Content-Type: application/json" \
  --data "$JSON_DATA" \
  https://ha.lan:8123/api/webhook/gps

and my automation:

alias: Update Zone from GPS
triggers:
  - webhook_id: gps
    trigger: webhook
    allowed_methods:
      - POST
      - PUT
    local_only: true
actions:
  - data:
      dev_id: router
      gps:
        - "{{ trigger.json.latitude }}"
        - "{{ trigger.json.longitude }}"
    action: homeassistant.set_location
