Create a new medication request (prescription or OTC). This is the compound walk-up operation: capture, approve, and dispense are applied in one call, each step gated by the caller's permissions (design §4). A front-desk caller with only the Inventory permission stops at Requested; a provider's submit collapses to today's one-step flow.

When supplied, the created dispense transaction is also attached to this estimate as an InvoiceLineItem in the same request. Used by the inline payments flow so dispense + bill land together.

Billing target for a clinic-dispensed (in-house / same-day) request. When set, the request's billable line is added to this existing estimate. Mutually exclusive with bool CreateMedicationRequestDto.CreateNewEstimate. Ignored for external (online-pharmacy / print-retail) requests, which are non-billable.

When true (and no string? CreateMedicationRequestDto.EstimateId), the request's billable line goes onto a new standalone draft estimate for the patient instead of the patient's current open draft.

"Therapeutic" | "Prophylactic" | "Metaphylactic". Required when the medication is antimicrobial.

Required for food-producing species. Free-form label text (e.g., "Meat: 28 days; Milk: 7 days").

UK CDR collector name (Schedule 2–5 controlled drugs).

UK CDR: was the collector's photo ID verified?

Populated when the request supplied string? CreateMedicationRequestDto.InvoiceId and an estimate line item was created in the same call.

The estimate the dispense was attached to — either the one the caller supplied or one auto-created/resolved server-side. Lets a client that had no estimate of its own adopt the server's estimate instead of failing to reconcile the line.

The estimate the request's billable line was placed on at creation (in-house / same-day requests). Null for external (non-billable) requests.

The Pending estimate line created for this request at creation, if any.

The lifecycle MedicationRequest recorded for this operation. The compound endpoint applies capture → approve → dispense as far as the caller's permissions allow; string? MedicationRequestResultDto.RequestStatus says where it stopped.

Lifecycle status after this call: requested | approved | dispensed.
