Request body

delayinteger

The number of minutes between a trigger_event being met and the workflow sending a message.

is_enabledboolean

When true, indicates that the workflow is enabled.

namestring required

The name of the workflow.

template_idstring required

The ID of the email template the workflow uses.

The event which triggers the workflow.

grant.expired and grant.deleted require a from sender address, because the grant that triggered them can no longer send email. Every other trigger accepts a workflow without one.

Workflows have no condition or filter field, so an enabled workflow sends for every matching event in its scope. High-volume triggers such as message.opened fire for every open of every tracked message the workflow covers.

Example request

{
  "delay": 5,
  "is_enabled": true,
  "name": "New booking confirmation workflow",
  "template_id": "14c00cc8-648c-4381-ad10-52641d9bac8e",
  "trigger_event": "booking.created",
  "from": {
    "email": "support@example.com",
    "name": "Support"
  }
}

Response

Success. Returns workflow.

request_idstring required

The ID of the request.
