Schedule invoice

Deprecation notice: The /v1/invoices endpoint is deprecated. Use the /v2/invoices endpoint instead. For details, see PayPal Invoicing Basic Integration.

Schedules an invoice, by ID, to send on a future date. At 07:00 on that date in the preferred time zone of the merchant's PayPal account profile, PayPal emails an invoice notification to the merchant and the customer, adds an online payment button to the customer’s view of the invoice, and updates the invoice status to SENT.

Note: To change the scheduled date, adjust the invoice date and update invoice. To send the invoice immediately, update the invoice date to today or to a date in the past.
