Payment Requests

Payment Requests represent the intention for a merchant to receive payment for goods and services. Payment Requests define the amount to be paid and the Asset Types that are acceptable for payment.

A Payment Request is shared with, and paid by, a patron. The Payment Flows Guide has more details regarding negotiation of Payment Requests.

Payment Requests have the following statuses:

new: after being created.
paid: after being paid with one or more transactions.
cancelled: after being cancelled or voided by the merchant.
expired: after expiry time is reached without being paid or cancelled.

Payment requests can also be refunded for a short period of time after being paid.

Payment request state transitions can be notified to webhooks.

Centrapay Payment Requests are serviced via two sets of endpoints; the “next” version (documented on this page) and the “legacy” version (documented at Legacy Payment Requests ).
