  description: 'This group of endpoints allows you to manage GL codes (accounting codes) for your business.


    GL codes are used to classify expenses for bookkeeping export. Businesses with a connected accounting integration (Xero, MYOB, NetSuite, QuickBooks, Business Central) cannot create or delete GL codes via the API — those are managed by the integration sync. Businesses with a manual integration or no integration can freely create, update, and delete GL codes. A manual integration is automatically created on the first POST if none exists.

      description: 'Creates or updates a GL code for the business (upsert by `code`).


        - If a GL code with the given `code` already exists, its `name` is updated.

        - If a previously soft-deleted GL code with that `code` exists, it is restored.

        - Otherwise a new record is created.


        Only available for businesses with a manual integration or no integration. If no integration exists, a manual integration is automatically created. Returns `400` if the business has a connected accounting provider (Xero, MYOB, NetSuite, QuickBooks, Business Central).
