Can't trigger HA from IFTTT

I have a Blurams doorbell that is IFTTT compatible so I am trying to get IFTTT to trigger an action in HomeAssistant, but for some reason it just isn’t working.

The thing that IFTTT is configured to trigger is a Webhook, with the following entries :-

The corresponding automation yaml is as follows :-

- id: '1616344541032'
  alias: IFTTT Doorbell Ring
  description: ''
  trigger:
  - event_data:
      action: call_service
    event_type: ifttt_webhook_received
    platform: event
  condition: []
  action:
  - target:
      entity_id: '{{ trigger.event.data.entity_id }}'
    service: '{{ trigger.event.data.service }}'
  mode: single

I can see from IFTTT that it is being triggered each time I press the doorbell but the automation in HA is not being triggered.

Any suggestions as to where I might be going wrong?

I have a similar automation:

- id: '0000000000001'
  alias: IFTTT webhook received
  description: ''
  trigger:
  - event_data:
      action: call_service
    event_type: ifttt_webhook_received
    platform: event
  condition: []
  action:
  - data:
      entity_id: '{{ trigger.event.data.entity_id }}'
    service: '{{ trigger.event.data.service }}'
  mode: parallel
  max: 10

The only difference seems to be in the action section.

Edit An afterthought… my URL in IFTTT is https://hooks.nabu.casa/etcetc

Great, I might try changing that later to see if it works.
I use DuckDNS rather than Nabu Casa, but I don’t expect that to be an issue.

Yeah, that seems to be working now - thanks!
