One receipt
API key required. Returns a single receipt by ID. Returns 404 unless the receipt belongs to the caller’s tenant — deliberately, so one tenant cannot probe another tenant’s receipt IDs (a foreign ID looks exactly like a missing one).
Authentication
AuthorizationBearer
Your Writ API key (writ_...) as an Authorization Bearer header. The sponsor token (writ_sp_...) is a separate credential used only for grants, revokes, and reinstate — it goes in the same Authorization header on those endpoints. In the Fern docs playground, paste the key here; it is stored in this browser only.
