Query Params

expand

array of strings, unique

Inline full canonical related resources on a single Invoice read. Supported values are payer, payee, attachments, and splits.payee. Payer/Payee expansion is caller-relative: the relationship resource that the caller can retrieve directly is returned byte-for-byte; the opposite, inaccessible relationship perspective is omitted. Unsupported values return 422 instead of being silently ignored. Expansions are not available on list/search rows.

Headers

X-Wingspan-Account

string

^(?:[A-Za-z0-9_.]{22}|[a-f0-9]{24})$

Select the Account for an Account-scoped operation. A direct ServiceAccount API key MUST supply this header, and the target must be within the ServiceAccount owner's or Authorization grant's Account boundary. A Person bearer may select an Account on which it has an active Stakeholder, and an Account session may select its bound Account (or a descendant only when the session explicitly includes descendants).
