I tried to do this. When we omitted the CompletionDate the API accepted the request but no appointment was displayed in the contact’s profile page. When we set a value for CompletionDate a note was created instead.
Can you send an example of an XML request that would correctly create an appointment.
Please find below the request we sent.
