I'm creating a ticket over API and set a custom due date via due_by (this is listed in the API documentation). But the ticket I created doesn't has the custom due date, but rather the default, set by the SLA.
Updating the due date afterwards also doesn't work.
Here is the JSON: '{"helpdesk_ticket": {"due_by":"2017-07-11T18:00:00+02:00"}}
What do I need to do, when I want to set a custom due date over API?
Best regards,
Lennart
