Book an appointment

POST/api/v1/booking/appointments

Since: 1.2.0
Auth: Bearer key
SDK: client.createAppointment()
operationId: createAppointment

Books a visit at a free slot from GET /booking/slots, in the same calendar as the clinic's site. The patient's lead is found by phone number (however it is written) or created; the booking moves the lead to the booked stage unless it is already at a visited, not interested or unreachable stage (the stage stays, the visit is stored). Reception gets a "Nowa wizyta" e-mail with an .ics file. Sending the same data again within 5 minutes returns the existing appointment instead of a second one. If the slot was taken in the meantime you get 409 with that day's free slots.

Request

Send the clinic's key in Authorization: Bearer (see API keys).

Body application/json

The appointment as JSON.

serviceIdstringrequired
The booking service, an id from the catalog's services.
resourceIdstringrequired
The specialist, the resourceId of the slot.
startAtintegerrequired
Start, epoch seconds (UTC): the startAt of a free slot.
patientobjectrequired
The patient.
Fields (3)
- namestringrequired
  Full name.
- phonestringrequired
  Phone number; the lead is matched by it, however it is written.
- emailstring
  E-mail address, optional.
notestring
Note for reception, e.g. the reason for the visit.
privacyNoticeVersionstringsince 1.7.0
The version of the information clause your form showed (from GET /privacy). Stored with the submission and its time; without it the submission is stored without a clause version.
marketingConsentbooleansince 1.7.0
true when the patient ticked the optional marketing box (label marketingText from GET /privacy). Recorded for SMS (when there is a phone) and e-mail (when there is an address) together with the clause version. It counts only with a valid privacyNoticeVersion: without it no consent is recorded and an earlier opt-out stays. For a returning patient booking an appointment, the e-mail consent covers only the address stored with their lead (or the given address when the lead had none). Omit it, or send false, when the box was not ticked.
