More then 1 value in RESTful command

Hi, i am trying to put 2 values in a rest command to control my ‘hue’ like lights. When i put in one value it works fine, but when i am putting 2 vallues in the command only the last one works.

Can anyone help?
Thanks in advance.

light:
  - platform: template
    lights:
      home_lights:
        friendly_name: "Home Lights"
        min_mireds_template: 1
        max_mireds_template: 200
        turn_on:
          service: rest_command.lamp_schouw_aan
        turn_off:
          service: rest_command.lamp_schouw_uit
        set_level:
          service: rest_command.lamp_schouw_temperature
          data:
            brightness: "{{ brightness }}"
            color_temp: "{{ color_temp }}"
        set_temperature:
          service: rest_command.lamp_schouw_temperature
          data:
            brightness: "{{ brightness }}"
            color_temp: "{{ color_temp }}"

rest_command:
  lamp_schouw_temperature:
    url: "http://192.168.0.80/Password/sw/7/on/{{ color_temp }}/0/{{ brightness }}" 

I still have no solution for this problem. Is it not posible to add 2 values in a command?

I know you can with a shell command, I presume you can with a rest command (but none of mine use variables). You could always shell out to a curl command if needed.

For example, this shell command works with multiple variables:

speak: ssh -i /config/ssh/id_rsa -o 'StrictHostKeyChecking=no' [email protected] '~/Scripts/tts_v2.sh -t "{{text}}" -s "{{speaker}}" -l {{volume}} -v "{{voice}}" -s "{{source}}"'
