# Approve Pennylane supplier invoices

Approve one or more Pennylane supplier invoices that are waiting for approval, by id. With dryRun (default true) each invoice is found and selected in the list, but not approved. With dryRun false it is approved, then read back. Approving an invoice already matched to a bank transaction marks it paid. Returns, per invoice, whether it was found, its label and amount, its status after the run, whether it was approved, and a warning when it is not waiting for approval or has no invoice number to single it out. Fails with a sign-in error when the browser is not signed in to Pennylane.
