Billing and invoices

GET/v1/invoices returns the invoices of the account the key belongs to, most recent first: the ones of the billing page.

Field	Meaning
`type`	`subscription`, `credit_purchase`, `auto_recharge` or `other`
`status`	`draft`, `open`, `paid`, `uncollectible`, `void`
`totalCents`, `amountPaidCents`	Tax included, in euro cents
`number`	The number printed on the invoice; `null` while it is a draft
`invoiceUrl`	The invoice's page, with its PDF

Filter on status=paid for the payment history. Invoices page with a cursor: pass nextCursor as cursor for the next, older page. Each response carries tenantName, so invoices fetched with the keys of several accounts can be told apart.
