To fire the entry event, send a POST request to the /interaction/v1/events endpoint. Include the contact key, the event definition key, and any additional data that’s required for the event. If the payload includes UTF-8 characters, include the Content-Type: application/json; charset=UTF-8 header.

If there are no errors, the API returns an HTTP 201 response that includes the eventInstanceId.

If the event definition key isn’t found, the API returns an HTTP 400 response.

The API also returns an HTTP 400 response if the contact isn’t active.
