Webhook Automation

Configuration
1

I have a service posting JSON data to an automation with a webhook trigger.
The automation triggers fine and I can see the JSON data that the service is posting. But how do I parse the JSON data and create sensors from that?

Thanks

With templating. The templating docs cover this in detail, but here’s one of mine, and here’s another.

@Tinkerer - amazing, just what I was looking for!

Now to throw a spanner in the works…

I have an index in the json that determines the type of message. Its either 1, 2 or 3.
How do I add the curly brackets inside an if statement?
Its pulling an error whichever way I try and do it.
This is what I have:

data_template:
  message: >
    {% if ({{ trigger.json.pack_id }}) == 1 %}
      Pack_ID is 1
    {% else %}
      Pack_ID is something else
    {% endif %}
  title: '{{ trigger.json.car_id }}'
service: notify.mobile_app_sm_n970f

data_template:
  message: >
    {% if trigger.json.pack_id == 1 %}
      First message
    {% elif trigger.json.pack_id == 2 %}   
      Second message
    {% elif trigger.json.pack_id == 3 %}   
      Third message
    {% else %}
      Uh-oh! Something's wrong!
    {% endif %}
  title: '{{ trigger.json.car_id }}'
service: notify.mobile_app_sm_n970f

Thats done it! Thanks!

This is my end code for creating a webhook and allowing a service to post json data to it containing sensor information:

event: mf_car_webhook
event_data_template:
  entity_id: |-
    {% if trigger.json.pack_id == 1 %}
      lat: "{{ trigger.json.lat }}"
      lng: "{{ trigger.json.lng }}"
      speed: "{{ trigger.json.speed }}"
      position_gmt: '{{ as_timestamp(strptime(trigger.json.gmt, "%Y-%m-%d %H:%M:%S")) | timestamp_custom("%d/%m/%y %H:%M") }}'
    {% elif trigger.json.pack_id == 3 %}
      ignition: "{{ trigger.json.state }}"
      ignition_gmt: '{{ as_timestamp(strptime(trigger.json.gmt, "%Y-%m-%d %H:%M:%S")) | timestamp_custom("%d/%m/%y %H:%M") }}'
    {% elif trigger.json.pack_id == 22 %}
      behaviour_event: "{{ trigger.json.type }}"
      behaviour_value: "{{ trigger.json.value }}"
      last_update: '{{ as_timestamp(strptime(trigger.json.gmt, "%Y-%m-%d %H:%M:%S")) | timestamp_custom("%d/%m/%y %H:%M") }}'
    {% endif %}
