POST /exemptions

Create an exemption

Create an exemption in the resolved organization. `customerId` is required and must belong to that organization; so must `transactionId` when you send one. `source` is not accepted on the body: an exemption created through this API is always recorded with source API. ARCHIVED is not an accepted `status` here; an archived exemption is absent from every read on this API.
