Permanently remove one recorded payment from an invoice.
AI agents call delete_invoice_payment to permanently remove resources in Clockify Time Tracking — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes financial transaction records (invoice payments). Even though the primary category is Destructive (deletion that cannot be undone), it also involves financial data manipulation. Under the prioritization rule, Destructive ranks above Financial when both apply, though this clearly overlaps both categories.
From the tool's definition Tool description states 'Permanently remove one recorded payment from an invoice.' The word 'Permanently' combined with 'remove' indicates irreversible deletion of financial data.
