SENDING webhooks

21

erm… not clear if you want to send a webhook from HA or to HA…

anyway,
When sending a webhook to HA, you can pass data in json format…

f.e:

trigger:
  - platform: webhook
    webhook_id: Fullfilment_Order_Shopify
  condition:
    - condition: template
      value_template: "{{ trigger.json.tracking_company == 'UPS' }}"

Hi, I am trying to send a webhook from Home Assistant to another system.
I have added this code to my configuration.yaml:
rest_command: example_request: url: "https://mywebhookurl"
Now when I want to create an automation, I can’t enter rest_command.example_request in the call service function. Also, I get an error message when I check configuration.yaml for errors:
Integration error: example_request - Integration ‘example_request’ not found.
Integration error: url - Integration ‘url’ not found.
Did I do something wrong?

I usually use the automations to do that where you use the restful command. The yaml looks like this

service: rest_command.example_request

Then in your config.yaml you would have that “example request” look like this.

rest_command:
  example_request:
    url: "https://whateverthewebhookurlis"

One more thing!!! You need to reboot HA before it’ll show up in the options.

Hi there, I am completely new in HA and want to send webhooks FROM HA TO e.g. Synology Surveillance station, from which I got the webhook token.

So I edited following to configuration.yaml:

rest_command:
  bewegung_erkannt:
    url: 'http://nas:5000/webapi/entry.cgi?api=SYNO.SurveillanceStation.Webhook&method="Incoming"&version=1&token="npgoOaGaH1cDbrQKWEptdKqrjioeHIJbtnZl1yg5YCHjcp37MeaCgMpAokCiy31X"'

And my automation is:

alias: XXX
description: ""
trigger:
  - type: powered
    platform: device
    device_id: 3d6d0d7a94cb183dfa3......(shortened)
    entity_id: 506d2c334bb2f6a28bb3.....(shortened)
    domain: binary_sensor
condition: []
action:
  - service: rest_command.bewegung_erkannt
    data: {}
mode: single

Problem: The webhook either isn’t triggered or doesn’t reach the Synology. But when I manually copy the webhook link to a browser it works. Also, when I put the link directly to the shelly motion sensor in “actions”. So the webhook link is ok. Has it maybe something to do with the " used inside the link? For that reason I used ’ at the beginning and at the end.

Any ideas how to solve this?

Try setting the url comman in “

Like this


table_blue:
  url: "http://192.168.1.34/win&PL=2&R=0&B=255&G=0"
27

This doesn’t work because HA cuts the URL after the first " inside the link. Additional the editor claims an error with " in the beginning and end

28

Nobody any ideas about this? I use “Studio Code Server” as editor and the link is shown correctly only when I use ’ instead of ", but still the webhook does not arrive on synology. What else I could try?

29

I tried also verify_ssl and method because Synology assumes GET, but also tried Post and put and I changed now to a simplier token “test1234”, but no change. The link is highlighted correctly in the editor (see line below link) and if I follow the link with the mouse, it open the browser and triggers correctly.

It never triggers in automation

UPDATE 26.11.2023:
Nobody here who can help? I tried already for a week, no success!
I tried following rest_commands:

rest_command:
  bewegung_erkannt1:
    url: 'http://nas:5000/webapi/entry.cgi?api=SYNO.SurveillanceStation.Webhook&method="Incoming"&version=1&token="test1234"'
    verify_ssl: false

  bewegung_erkannt2:
    url: http://nas:5000/webapi/entry.cgi?api=SYNO.SurveillanceStation.Webhook&method="Incoming"&version=1&token="test1234"
    verify_ssl: false

  bewegung_erkannt3:
    url: >
      'http://nas:5000/webapi/entry.cgi?api=SYNO.SurveillanceStation.Webhook&method="Incoming"&version=1&token="test1234"'
    verify_ssl: false

  bewegung_erkannt4:
    url: >
      'http://nas:5000/webapi/entry.cgi?api=SYNO.SurveillanceStation.Webhook&method=%22Incoming%22&version=1&token=%22test1234%22'
    verify_ssl: false

  bewegung_erkannt5:
    url: >
      "http://nas:5000/webapi/entry.cgi?api=SYNO.SurveillanceStation.Webhook&method=%22Incoming%22&version=1&token=%22test1234%22"
    verify_ssl: false

But no success. Here is what the LOG says.

Please help

I’m new to this as well. But have you tried to replace nas:5000 with the actual IP of your synology NAS?

31

nas:5000 ist the internal http address and this works with browsers

32

No, it is the machine name, and not the IP address…

So I agree with this :thinking:

33

Oh wow, when I use the IP instead of the name, it works. Great! Thanks!

But is there a way to use names? I have a fix IP anyway for the NAS but it would be easier for network administration, in case I change it in future.

Thanks

PS: but it works when I tried to send webhooks from homeassistant to homeassistant:8123. Here I did not need the IP address.
