# Process a register

POST https://gateway.ixopay.com/api/v3/transaction/{apiKey}/register
Content-Type: application/json

Registers a customer's payment instrument for future use (Debit or Preauthorize).

Reference: https://ixopay.ferndocs.com/developer-hub/api-reference/transaction-api/transaction/process-register

## Authentication

- `Authorization` header (basic auth, required) — Basic authentication of the form `Basic <base64(username:password)>`.

## Request

### Path parameters

- `apiKey` (string, required) — API Key of Connector

### Body (application/json)

This endpoint expects a Register.

- `merchantTransactionId` (string, required) — Your own unique identifier for this registration. Must be unique per merchant.
- `additionalId1` (string, optional) — Optional free-form identifier for your own reconciliation (e.g. order or invoice number).
- `additionalId2` (string, optional) — A second optional free-form identifier for your own reconciliation.
- `extraData` (map from string to string, optional)
- `pspPassthroughData` (map from string to string, optional)
- `merchantMetaData` (string, optional) — Opaque metadata echoed back unchanged in callbacks and the transaction status response.
- `successUrl` (string, optional) — URL the customer's browser is redirected to after successfully registering their payment instrument.
- `cancelUrl` (string, optional) — URL the customer's browser is redirected to if they cancel a redirect-based registration flow.
- `errorUrl` (string, optional) — URL the customer's browser is redirected to if a redirect-based registration flow fails.
- `callbackUrl` (string, optional) — Server-to-server URL IXOPAY calls with the final registration result; overrides the connector's configured default callback URL.
- `transactionToken` (string, optional) — Token identifying a previously tokenized/stored payment instrument, instead of raw card data.
- `description` (string, optional) — Free-text description of the registration, shown to the customer or PSP where supported.
- `transactionIndicator` (enum, optional) — Classifies the transaction for card-scheme compliance (e.g. recurring, card-on-file, MOTO) — required by some acquirers/schemes for off-session charges.
  - Allowed values: `SINGLE`, `INITIAL`, `RECURRING`, `FIRST-CARDONFILE`, `CARDONFILE`, `CARDONFILE-MERCHANT-INITIATED`, `MOTO`
- `customer` (Customer, optional)

- `referenceUuid` (string, optional) — UUID of a previous register transaction on the same merchant. Used by the register-with-expiry-update flow to point at the existing token whose expiry date should be patched. When set together with extraData.expiryMonthUpdate / expiryYearUpdate, the request becomes a card-data-less expiry refresh — no PAN/CVV is required.
