Get a transfer by ID (deprecated alias)
**Deprecated** — use `/v1/api/payment` instead. This path is kept for SDK back-compat and will be removed in a future major release. Both paths share the same handlers; only the URL differs. 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.
Authorization
apiKey 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.

**Deprecated** — use `/v1/api/payment` instead. This path is kept for SDK back-compat and will be removed in a future major release. Both paths share the same handlers; only the URL differs. 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 transfers (deprecated alias)
**Deprecated** — use `/v1/api/payment` instead. This path is kept for SDK back-compat and will be removed in a future major release. Both paths share the same handlers; only the URL differs. Retrieve a list of payments. Filters: `type` (DEBIT/CREDIT/REVERSAL/FEE/ADJUSTMENT/DISPUTE/RESERVE/SETTLEMENT/UNKNOWN), `subtype`, `parent_transfer`, `source`, `merchant` (override scoping; must be company-owned). `scope=company` widens scoping from the auth context's primary merchant to all the company's merchants. `expand` accepts comma-separated keys: merchant, merchant_identity, instrument, parent.
