API release news 03/26

MARCH 2026

1.) Breaking Change: Update to “Get Search criteria fields” endpoint.

Get Search criteria fields

We resolved an inconsistency regarding how possible options are returned for select fields. Previously, multiselect fields returned all options (both active and inactive), while single-select fields returned only active ones.

Update: Multiselect fields now behave the same as single-select fields and will only return active options. Inactive options are no longer included in the response payload.

2.) Link Email Attachments to Appointments

Create Appointments

A new optional parameter, mailMessageId, has been added to the calendar creation action. This feature allows attachments from a specified email to be automatically linked and saved to the ‘Files’ tab of the newly created appointment in the onOffice App, mirroring the functionality available in onOffice enterprise.
