Security note: Keep this URL safe. Anyone that has access to the URL will be able to create tasks in your Space.

Creating your first task

The Webhook URL accepts the HTTP POST method with the header Content-Type: application/json with the task details as JSON body. If you are familiar with curl, you can try to create a task right away curl -XPOST -H "Content-type: application/json" -d '{"text": "A task from the new webhook URL"}' '' 

More than just text

You can add a description, assign the task, set a start date and a due date. Here is the full payload that is accepted by the Webhook URL.

{ "text": "string", "description": "string", "assignedTo": [ "USERID" ], "assignedToEmail": [ "user@email" ], "startDate": "2019-03-20", "dueDate": "2019-03-20", "subListId": "5a9cf7219285..." // The list ID within the space }

Please note: dates should be in UTC
