Requesting a third-party API and writing the result to a variable

Installation Home Assistant OS

Good day!

I want to make a request to a specific API when a trigger fires, I understand how to do this kind of automation.
But in order to request this API, I first need to login and get the token in JSON format:

https://192.168.1.10:8080/login?password=12345

{
    "success": 1,
    "sid": "Dui79RfO"
}

I need to use the resulting “sid” value for subsequent requests:

https://192.168.1.10:8080/settings/channels/name?sid=Dui79RfO

Please tell me how can I save the value received in the request for future use?
I am making requests using “RESTful Command”, it might be better to use templates for this.

Use two restful sensors one for logging in an storing the token and one for requesting the data :blush:

Thank you very much for the advice, I didn’t know about the possibility of creating “rest” sensors.
I was able to get the token and write it:

- platform: rest
  resource: https://192.168.1.10:8080/login?password=12345
  verify_ssl: false
  name: get token
  value_template: "{{ value_json.sid }}"

But I can’t imagine how to substitute it in the request.
Tried specifying directly in the query string:

- platform: rest
  resource: https://192.168.1.10:8080/settings/channels/name?sid=sensor.get_token
  verify_ssl: false
  name: device name
  value_template: "{{ value_json.value }}"

Also tried to specify in headers:

- platform: rest
  resource: https://192.168.1.10:8080/settings/channels/name
  verify_ssl: false
  name: device name
  value_template: "{{ value_json.value }}"
  headers:
    sid: "{{ states('sensor.get_token') }}"

But in return I get the state “unknown”.
Please tell me what am I doing wrong?

Sorry for the late reply:

You would need to use resource_template instead of resource. See below:

- platform: rest
  resource_template: "https://192.168.1.10:8080/settings/channels/name?sid={{states('sensor.get_token')}}"
  verify_ssl: false
  name: device name
  value_template: "{{ value_json.value }}"
