Clickatell API to send SMS

Hi, I have the following API to send SMS:

curl -i
-X POST
-H “Content-Type: application/json”
-H “Accept: application/json”
-H “Authorization: XXXXXXXXX”
-d ‘{“content”: “87684454”, “to”: [“000000000”]}’
-s https://platform.clickatell.com/messages

I set up the API Action as following:

But doesn’t work.

It is well done the set up of the api or is it wrong?

Thank You
