# Create or update an accounting code

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).
