Payment Coordinator

Customer check-in at a payment location, and payment creation, capture, refund and cancel.

Payment locations, customer check-in, and the payment lifecycle: create a payment, then capture, cancel or refund it.

The V1 check-in and payment-creation endpoints (POST /v1/checkin/{paymentLocation}, POST /v1/checkin/{paymentLocation}/register-member, POST /v1/payments, POST /v1/payments/init) are marked deprecated in the spec — prefer the V2 equivalents.
