Execute rest_command with variable URL etc

Configuration
1

Hi,

I wonder if there is any way to create a generic switch/command based on REST that I can change the URL for from a script or automation?

Example:

I have a restful command setup like:

restful_command:
testcall:
url: ‘http://192.x.x.x/api/urlX’
method: ‘post’

But then in realtime I’d like to change the url to ‘http://192.x.x.x/api/urlY’.

Is anything like that possible? I’ve been trying in a few different ways now but I’m stuck.

Thanks!!

I’ve seen it in other applications but idk how to apply to you, looks like this:

style_template: “return 'background-image: url(”/local/icons/’ + state + ‘_left_1.png");’"

in this url “state” is variable

According to the docs the url parameter of rest_command does support templates. One way I can see using this is to create an input_text entity, and use that as the value for the url. E.g.:

input_text:
  rest_cmd_url:
    name: URL for RESTful Command

rest_command:
  rest_cmd:
    url: "http://192.x.x.x/api/{{ states('input_text.rest_cmd_url') }}"

script:
  test_rest_cmd:
    sequence:
      - service: input_text.set_value
        data:
          entity_id: input_text.rest_cmd_url
          value: "urlY"
      - service: rest_command.rest_cmd

Actually, the doc also says, “Service call support variables for template stuff.” Unfortunately, it’s not very explicit and there’s no examples, but I would guess, if this is the case, then it might be even simpler. Maybe something like:

rest_command:
  rest_cmd:
    url: "http://192.x.x.x/api/{{ url }}"

script:
  test_rest_cmd:
    sequence:
      service: rest_command.rest_cmd
      data:
        url: "urlY"

I haven’t tried it so I might not have the details exactly correct.

Actually both ways worked!! Thanks a bunch, I don’t think I would’ve solved that on my own! :grinning:

Hi

Sorry, could you help. I 've tried the same thing but in my case the REST call returns 400 - bad request.

rest_command:
  mediaruimte_dimmer:
    url: http://192.168.0.13:8081/outputs/bec5-8/state
    method: PUT
    payload: '{"bri": {{ url }}}'
    content_type:  'application/json; charset=utf-8'
    verify_ssl: false

When executing this in a script or elsewhere I get the 400 error:

test_rest_cmd:
  sequence:
  - data:
      url: '30'
    service: rest_command.mediaruimte_dimmer

What could be wrong?

thx
Koen
