+- The endpoint operates asynchronously. The data is first stored and internally verified before being submitted to BO4. To track the processing in the API, a ticketId is returned. The ticket ID must be used to check the status of the API call. Within the API, various checks are performed. For example, it checks that the email address matches the format aaaa@bbbb.xxx. It also checks that the phone number does not contain alphanumeric values. However, it does support phone numbers like "035-1234567".
