Mark a transaction paid

Settles an open invoice or bill: an INVOICE becomes INCOME, a PENDING expense or deduction becomes CONFIRMED. This is the moment money actually moves, which is why it is what posts the journal entry and moves the tax liability — raising the record did neither. Only a PENDING invoice or bill can be settled.

Required scope

The access token must carry this scope. A token missing it gets 403 Forbidden. Grant them to an API client under Settings → Company → API, and to a teammate under Employee → Permissions.
