Create a refund (reversal)

Create a reversal (refund) for a succeeded payment.

POST
/v1/api/payment/{id}/reversals

Authorization

apiKey
x-easy-api-key<token>

Merchant API key. Publishable keys (pk_test_* / pk_live_) are safe for browser/frontend use and carry a limited scope set (sessions, payment_instruments, customers, orders writes; products, product_prices, payment_links reads). Secret keys (sk_test_ / sk_live_*) grant full admin access and must only be used server-side.

Create a payment (customer charge)

Charge a customer's payment instrument. Body mirrors Finix's POST /transfers payload. The merchant defaults to the API-key/JWT context but can be overridden for sub-merchant routing.

Get a payment by ID

Retrieve a payment by its ID. `expand` accepts comma-separated keys: merchant, merchant_identity, instrument, parent. `scope=company` widens scoping from the auth context's primary merchant to all the company's merchants.
