# List Payments (Transactions)

GET https://api.crisscross.money/v1/payment

Lists transactions for one or more merchants using cursor-based pagination.
If no cursor is provided, the API returns the first 50 transactions by default.


Reference: https://docs.crisscross.money/api-reference/collect/payments/manage-payments/list-transactions

## Request

### Query parameters

- `merchantIds` (string, required) — Comma-separated list of merchant IDs.
- `cursor` (string, optional) — Cursor for the next page of results.
- `backCursor` (string, optional) — Cursor for the previous page of results.

## Response

### 200

Transactions retrieved successfully.

- `transactions` (list of TransactionFullStateResponse, optional)
- `nextCursor` (string, optional) — Cursor for the next page of results (if available).
- `backCursor` (string, optional) — Cursor for the previous page of results (if available).

## Errors

### 400 Bad Request Error

Invalid request parameters.

- `message` (string, required) — Human-readable description of what went wrong.
- `error` (string, required) — Error category. Most endpoints return the HTTP reason phrase (e.g. "Bad Request", "Unauthorized", "Conflict", "Unprocessable Entity", "Internal Server Error"). Some return a machine-readable snake_case code instead — notably the FX and rate-lock rejections on checkout session creation and payment initiation, where several distinct codes share a single HTTP status. Where a code is present it is the finer discriminator and is safe to branch on.
- `statusCode` (integer, required) — HTTP status code, mirroring the response header. The response header is the source of truth.

### 401 Unauthorized Error

Unauthorized.

- `message` (string, required) — Human-readable description of what went wrong.
- `error` (string, required) — Error category. Most endpoints return the HTTP reason phrase (e.g. "Bad Request", "Unauthorized", "Conflict", "Unprocessable Entity", "Internal Server Error"). Some return a machine-readable snake_case code instead — notably the FX and rate-lock rejections on checkout session creation and payment initiation, where several distinct codes share a single HTTP status. Where a code is present it is the finer discriminator and is safe to branch on.
- `statusCode` (integer, required) — HTTP status code, mirroring the response header. The response header is the source of truth.

## Types

### TransactionFullStateResponse

Complete transaction state response with full details and history.

- `currentState` (string, required) — Current transaction state
- `previousStates` (list of string, required) — Array of previous transaction states
- `processor` (string, required) — Payment processor used for the transaction
- `merchantName` (string, required) — Merchant name
- `transactionId` (string, required) — Unique transaction identifier
- `amount` (double, required) — Transaction amount as a decimal in **major** units (e.g. `10` = 10.00 KES) — unlike session creation, which takes minor units.
- `transactionType` (string, required) — Transaction type
- `paymentMethodId` (string, required) — Payment method identifier
- `currency` (string, required) — Transaction currency
- `merchantReference` (string, required) — Merchant reference
- `transactionStates` (list of map from string to any, required) — Detailed transaction state history
- `paymentAttributes` (map from string to string, optional) — Payment-specific attributes and metadata
- `identifiers` (map from string to string, optional) — Additional transaction identifiers. For collections this includes `sessionId` — the checkout session the transaction belongs to — and `payerId`, the persistent [payer identifier](/payer-id).
- `paymentInstrument` (map from string to any, optional) — Payment instrument details when applicable.
- `processorReference` (string, optional) — Payment processor reference
- `financialTransactionReference` (string, optional) — Financial transaction reference from the processor
- `currentAttemptId` (string, optional) — Current attempt identifier
- `batchPayoutId` (string, optional) — Batch payout identifier, if the transaction is part of a batch payout
- `refundTransactionIds` (list of string, optional) — Transaction identifiers of all refunds processed against this transaction. Each entry can be passed to `GET /payment/{transactionId}` to retrieve full refund state. UUID v7.
