Testing Incoming Webhooks using cURL
Last updated: 2020-10-09 Contributors 
Edit this pageA simple way to test an Incoming Webhook and to make formatting messages easier is to use a simple command-line tool called cURL. Using this simple technique, you can place your message contents in a stand alone file, and then post that file to the URL of an Incoming Webhook.
Let's begin by creating the file test.json using the following contents:
{
"attachments": [
{
"type": "Card",
"fallback": "Something bad happened",
"color": "#00ff2a",
"intro": "There was a disturbance in the force.",
"author": {
"name": "Ben Kenobi",
"uri": "https://en.wikipedia.org/wiki/Obi-Wan_Kenobi",
"iconUri": "https://imgur.com/eaL6deH"
},
"title": "I felt something...",
"text": "...as if millions of voices suddenly cried out in terror and were suddenly silenced.",
"fields": [
{
"title": "Where",
"value": "Alderaan",
"style": "Short"
},
{
"title": "What",
"value": "Giant explosion",
"style": "Short"
}
]
}
]
}
Then from the same directory in which you created the above file, run the following command -- being sure to use the Webhook URL you created on your own.
% curl -d @test.json -H 'Content-Type: application/json' \
