Only while it can still be paid, and one invoice email a store in five minutes. A payment link has no address on it until it is sent or paid, so the first send names one in `email`. The link is that buyer's from then on: the page it is paid on stops asking who is paying, and a later send with no `email` goes to the same address. It cannot be sent to another address once somebody has started paying it (`link_in_use`). A link that can be paid more than once stays nobody's: every send names an `email`, which is only where that one email goes, and it may be sent to as many people as you like at the same pace. Needs the `invoices.write` permission (Raise Invoices). It sends an email, and is counted against a budget of its own: 60 in ten minutes for each key. ## OpenAPI ````yaml /api-reference/openapi.json post /stores/{storeId}/invoices/{orderId}/send openapi: 3.1.0 info: title: Shoply API version: '1' description: >- Everything a store's own server can do with a secret API key: its catalogue, orders, customers, marketing, finance and the rest of what the dashboard does.
