How to Declare Authorizations HTTP POST msteam? - http-post

Question

I have try completed input text then post to webhook.
below code :
{
"#type": "MessageCard",
"#context": "",
"themeColor": "0076D7",
"summary": "Larry Bryant created a new task",
"sections": [{
"activityTitle": "![TestImage]()Larry Bryant created a new task",
"activitySubtitle": "On Project Tango",
"activityImage": "image5.png",
"facts": [{
"name": "Assigned to",
"value": "Unassigned"
}, {
"name": "Due date",
"value": "Mon May 01 2017 17:07:18 GMT-0700 (Pacific Daylight Time)"
}, {
"name": "Status",
"value": "Not started"
}],
"markdown": true
}],
"potentialAction": [{
"#type": "ActionCard",
"name": "Add a comment",
"inputs": [{
"#type": "TextInput",
"id": "comment",
"isMultiline": false,
"title": "Add a comment here for this task"
}],
"actions": [{
"#type": "HttpPOST",
"name": "Send mail",
"target": "webhook/######",
"body": "{'text':''}"
}]
}]
}
but i tried with my api then send mail with authorizations in headers.
below code :
POST webhook/######
Content-Type: application/json
{
"#type": "MessageCard",
"#context": "/extensions",
"themeColor": "0076D7",
"summary": "Larry Bryant created a new task",

}, {
"name": "Due date",
"value": "Mon May 01 2017 17:07:18 GMT-0700 (Pacific Daylight Time)"
}, {
"name": "Status",
"value": "Not started"
}],
"markdown": true
}],
"potentialAction": [{
"#type": "ActionCard",
"name": "Add a comment",
"inputs": [{
"#type": "TextInput",
"id": "comment",
"isMultiline": false,
"title": "Add a comment here for this task"
}],
"actions": [{
"#type": "HttpPOST",
"name": "Send mail",
"target": "domain.com/api/sendmail",
"headers": [
