Restfull command to LINE Messaging API

Configuration
1

Hi,

I would like to set up a rest_command to use Line Messaging API chat bot (LINE is a messaging app i use) as a notification platform.

LINE Messaging API

According to LINE Messaging API documentation, the webhook should be as below :

curl -v -X POST https://api.line.me/v2/bot/message/push \
-H 'Content-Type:application/json' \
-H 'Authorization: Bearer {channel access token}' \
-d '{
    "to": "U4af4980629...",
    "messages":[
        {
            "type":"text",
            "text":"Hello, world1"
        },
        {
            "type":"text",
            "text":"Hello, world2"
        }
    ]
}'

I’ve created a rest_command in my configuration.yaml but i can’t get it work and always get an error 400. My access token and ID are correct as i can POST using Postman.

rest_command:
  line_test:
    url: 'https://api.line.me/v2/bot/message/push'
    method: POST
    headers:
      Authorization: Bearer {xxxxxxx}
      Content-Type: application/json
    payload: '{"to": "lineidxxxx", "messages": [{"type": "text","text": "Hello, world1"}]}'
    content_type:  'application/json; charset=utf-8'

Any idea what might be wrong in my formatting ?

Edit : sorry i find the solution = Hass reboot was needed …
