An `account` source codes the fixed, cash-side line of its transactions; every other source codes the editable lines, and `accounts_payable` sets the account bills are posted to when they sync. Sources are things you can already list through the API (accounts, cards, merchants, contacts, ...); the value is a dimension value id, or for custom-field dimensions the raw field value. One source maps each dimension at most once, so writing the same source and dimension again replaces the earlier mapping. type: object properties: id: type: string description: Mapping id with the `accounting_mapping_` prefix. example: accounting_mapping_2rj4l7hmrrrcv connectionId: type: string description: The connection the mapping belongs to. example: accounting_connection_2rj4l7hmrrrcv source: $ref: '#/components/schemas/accounting-mapping-source' dimensionKey: type: string description: >- The dimension this mapping codes, a `key` from `GET /v2/accounting/dimensions`. example: account valueId: type: string description: >- The dimension value applied, from `GET /v2/accounting/dimensions/{dimensionKey}/values`.
