• Production API

The desk reached the guest about a room that has freed up — OPERA’s Can Move followed by the phone call — and keeps it for them: one room-night of the asked type on every ledger night of the stay goes into the ledger’s blocked count until offer_deadline (the desk’s own, or the property’s waitlist_offer_hold_minutes, 30 unset). Refuses when a night of the stay has nothing left to keep. Re-offering re-stamps offered_at and restarts the clock but keeps the hold it has rather than taking a second room. Accept books the kept room; cancel gives it back; an offer left past its deadline lapses (lapse_waitlist_offer) and the room goes to the next entry. Refuses an entry that is already accepted, cancelled, or expired. At a house with waitlist_offer_messaging on, the offer is also sent to the guest — by SMS, or email when there is no mobile number — with a claim link, unless notify_guest is false.

Effects: modify hospitality.waitlist_entry; modify hospitality.availability_day; create hospitality.guest_message; create hospitality.guest_conversation; modify hospitality.guest_conversation; link hospitality.link.guest_conversation_for_person; link hospitality.link.guest_conversation_at_property; link hospitality.link.guest_conversation_anchored_to_reservation; link hospitality.link.guest_message_in_conversation.

Request Body^required

Media typeapplication/json

object

branch

Apply against an open branch’s overlay view instead of the canonical (main) plane. The action’s writes land in the branch’s copy-on-first-write overlay, its events in the branch’s own stream, and the invocation is journaled for merge-by-replay. Branch writes are action-only, so this is the write-side entry point to a branch (POST /v1/branches forks one).

string format: uuid

params

required

object

notes

What was offered, and what the guest said (recorded as offer_notes)

string

notify_guest

Send the offer to the guest when the house sends waitlist offers (default true)

boolean

offer_deadline

Keep the room until (defaults to now + the property's offer clock)

string format: date-time

return_modified

When true, the response carries modified_objects and modified_links projections — the engine reads the event log inside the same transaction so the projection observes the handler’s own writes.

boolean

target

required

object

id

required

string format: uuid

object_type

required

Allowed value: hospitality.waitlist_entry

Responses

200

Action applied. modified_objects and modified_links populated when return_modified: true was supplied.

Media typeapplication/json

ApplyActionResponse

Envelope returned by the Aerandil action engine. correlation_id ties every event emitted by this invocation; modified_objects and modified_links project the events the handler emitted (per the action’s declared effects); warnings carries any non-blocking soft-validator observations.

object

correlation_id

required

Per-invocation correlation id; matches events.correlation_id for every event this action appended.

string format: uuid

modified_links

required

Links established or removed by this invocation. Empty when the caller did not request return_modified.

Array<object>

object

from_id

required

string format: uuid

from_type

required

string

kind

required

Allowed values: linked

link_type

required

Allowed values: hospitality.link.guest_conversation_for_person hospitality.link.guest_conversation_at_property hospitality.link.guest_conversation_anchored_to_reservation hospitality.link.guest_message_in_conversation

to_id

required

string format: uuid

to_type

required

string

modified_objects

required

Objects created, modified, or soft-deleted by this invocation. Empty when the caller did not request return_modified.

Allowed values: modified created

object_type

required

Allowed values: hospitality.waitlist_entry hospitality.availability_day hospitality.guest_message hospitality.guest_conversation

warnings

Non-blocking soft-validator observations emitted during this invocation (e.g. comp-authority over-limit, recipe pour-cost over sell-price). Absent when no warnings were emitted.

Array<object>

object

message

required

Human-readable summary, suitable for logging or operator-UI surfacing.

string

object_type

required

Object type the warning was raised against.

string

property

Property the warning anchors to, when a single field is the locus. Absent for multi-field rules.

string

rule

required

Stable kebab-case rule identifier (e.g. comp-authority-over-limit).

string

Example

{
  "modified_links": [
    {
      "kind": "linked",
      "link_type": "hospitality.link.guest_conversation_for_person"
    }
  ],
  "modified_objects": [
    {
      "kind": "modified",
      "object_type": "hospitality.waitlist_entry"
    }
  ]
}

Conflict — concurrent modification or unique constraint violation.

422

Validation error — parameter validation or business-rule violation.
