posting Incoming webhook to MS Teams using curl command

we are using azure devops pipeline and web hook notifications to slack.
For below notification I changed the webhook url to outlook. But not working it says `Bad payload received by generic incoming webhook`. How to customize payload for teams. 

curl -H 'Content-Type: application/json' --data-urlencode 'payload={"username": "Application","text": "Application_IOS_EnterpriseBuild","attachments": [
{
"color": "#F35A00",
"fields": [
{
    "title": "Pipeline",
    "value": "'"$(Agent.JobName)"'",
    "short": true
}
]
},
{
"color": "#F35A00",
"fields": [
{
    "title": "commit_sha",
    "value": "'"$GIT_RELEASE_NOTES "'",
    "short": true
}
]
},
{
"color": "#F35A00",
"fields": [
{
    "title": "Status",
    "value": "'"Started"'",
    "short": true
}
]
}
]}' https://outlook.office.com/webhook/6ab53-e6a3-4b3e-ae06-a65cdaf3b31e/IncomingWebhook/ae2d458317eb4b20a3581fdd01aeecd3/e966e859-4ec9-497a-b1b8-5e6fadb19404(sample)
