Approve purchase invoice
Approve a purchase invoice in circulation so it can be paid.
POST https://cotlet.dev/api/v1/procountor/invoices/{invoice_id}/purchase-invoice/approve
write Confirm
Does what Approve does in the Verification view: adds an approval stamp. If verifiers are specified, the invoice must be verified first. Once all approvers have approved, the status becomes Approved, the invoice counts as a business transaction and can be paid in the Payment view. This tool does not pay it. By default you confirm each call; you can switch that off for this tool.
Parameters
| Name | Type | Description |
|---|---|---|
| invoice_id string required | string | Purchase invoice ID from list_purchase_invoices. |
| comment string | string | Optional comment stored with the stamp. |
