How do I add a condition on a webhook trigger?

Configuration Frontend
1

I have a webhook, and that webhook gets POSTed using a JSON {"event": "foo"}. How do I set a condition so my automation only runs for certain events? I can’t use the Numeric state or State conditions, since they won’t let me access the trigger, since it isn’t an entity.

If you make an automation with no actions, you can view the trace & the variables that the automation creates under the Traces page, in the Changed Variables tab on the trigger node:

…
trigger:
  platform: webhook
  webhook_id: …
  json:
    event: ABC

You can then use a “Template condition” in the automation editor. For example, {{ trigger.json.event == 'ABC' }} will return true for the above event. In YAML format,

condition: template
value_template: "{{ trigger.json.event == 'ABC' }}"

Hi,

I have a similar problem/question. receiving following data: (webhook post from Unifi Protect)

Shown under Changed Variables

this:
  entity_id: automation.web_hook_test
  state: 'on'
  attributes:
    id: '1726530021578'
    last_triggered: '2024-09-18T18:44:01.393831+00:00'
    mode: single
    current: 0
    friendly_name: web hook test
  last_changed: '2024-09-18T18:53:50.947392+00:00'
  last_reported: '2024-09-18T18:53:50.947392+00:00'
  last_updated: '2024-09-18T18:53:50.947392+00:00'
  context:
    id: 01J837QMF32Y6KDPYKYTKSXQ4A
    parent_id: null
    user_id: null
trigger:
  platform: webhook
  webhook_id: XXXXXXXXXXXXXXXXX'
  json:
    alarm:
      name: Person of interest
      sources: []
      conditions:
        - condition:
            type: is
            source: face_of_interest
      triggers:
        - device: 28704E12AE9F
          value: Boris
          key: face_of_interest
    timestamp: 1726685684188
  query:
    __type: <class 'multidict._multidict.MultiDictProxy'>
    repr: <MultiDictProxy()>
  description: webhook
  id: '0'
  idx: '0'
  alias: null

Trying with the following automation:

alias: web hook test
description: ""
trigger:
  - platform: webhook
    allowed_methods:
      - POST
      - PUT
    local_only: true
    webhook_id: "XXXXXXXXXXXXX"
condition:
  - condition: template
    value_template: "{{ trigger.json.alarm.triggers.value == 'Boris' }}"
action:
  - action: tts.speak
    metadata: {}
    data:
      cache: true
      media_player_entity_id: media_player.googlehome8818
      message: Hallo
    target:
      entity_id: tts.home_assistant_cloud
mode: single

But just can’t get the condition to pass. Tried all different variations of path to the value. But I am starting to think I took a wrong approach.

Would be great if some could take a look.

Thanks

Boris
