Invoices that are sent to your customers can contain links to the invoice pdf, credit notes, and the hosted invoice page. These links expire 30 days after the invoice due date up to a maximum of 60 days from the due date or the finalization date if there’s no due date.
If you send your customer an invoice using the dashboard or API, they will be able to enter their email address in the recovery flow when they open an expired link. This will resend them the invoice with a fresh link.
If you did not send your customer the invoice, they will see a message to contact you with your support information.
You can also always follow the below two methods to generate a fresh link to send your customers. These links will always be active for 10 days or more depending on when the invoice is due.
Dashboard: Open the invoice in the dashboard and resend the invoice or copy the hosted invoice page link.
API: Retrieve the invoice via our API and any of the links returned in the object response like invoice_pdf or hosted_invoice_url will be active links.
