Get Collections With Property
GET/api/collections/GetCollectionsWithProperty
Tier: Internal — subject to change without notice.
Single-property Collection lookup, used by file-import tooling to resolve a collection reference from a human-readable value rather than its id.
All three query parameters must be present in the query string for the request to route — values may be empty (e.g. &mappedPropertyName=), but omitting a parameter entirely returns 405 Method Not Allowed, because action selection then falls through to the POST-only overload on the same route (verified live 2026-07-03). When resolving via {mappedPropertyName}, the search is additionally restricted to active collections.

Returns a 0- or 1-element Collections.CollectionDetailDto list. When
{propertyName} is "Name", a no-match result is 200 with an
empty list rather than a 400.
Extended-property path only: an unknown extended property name (NotFound "Extended Property: {name}"), an unparseable value for the property's data type (NotFound "Invalid data type"), or zero matches (NotFound).
