Unlike v1 (scoped under `/{account_id}/{payment_link_id}`), v2 only takes the link id — the owning account is resolved and access-checked from the link itself. ## OpenAPI ````yaml https://payment-b2b.singapay.id/api/docs/merchant-api.json get /api/v2.0/payment-link/{link_id} openapi: 3.1.0 info: title: Singa Merchant API description: >- OpenAPI specification for the merchant/partner HTTP API. All routes below are additionally protected by `ip.whitelisted.merchant` — the caller IP must be registered for the credential or merchant. Obtain a JWT using `POST /api/v1.0/access-token/b2b` (Basic auth) or `POST /api/v1.1/access-token/b2b` (X-Signature) before calling secured endpoints. version: 1.0.0 servers: - url: https://sandbox-payment-b2b.singapay.id description: >- API host. Paths include `/api` prefix (see `RouteServiceProvider`). Replace scheme/host with your environment. security: [] tags: - name: Security description: >- Merchant authentication (`OauthMerchantTokenController`). **v1.1** B2B token uses `X-CLIENT-ID`, `X-PARTNER-ID`, and `X-Signature` (no Basic auth). Secured routes also require the issued Bearer JWT plus `X-PARTNER-ID`. - name: Accounts description: >- Account management (`routes/merchantApiRoute.php`, `v1.0`). Path parameter `{id}` is always the account ULID. - name: Balance Inquiry description: >- Merchant and per-account balance inquiry (`BalanceController`, `v1.0`). Path `account_id` is the account ULID. - name: Statements description: >- Per-account statement list and detail (`AccountController::accountStatements`, `accountStatementDetail`, prefix `v1.0/statements`). Flugger responses; detail path param `{statement_id}` maps to `statements.transaction_id`. - name: Payment Link description: >- Payment link CRUD and payment-method catalog (`PaymentLinkApiController`, prefix `v1.0/payment-link-manage`). `account_id` is ULID; `payment_link_id` is numeric `payment_links.id`. - name: Payment Link History description: >- Payment link transaction/history listing and detail (`PaymentLinkApiController`, prefix `v1.0/payment-link-histories`). `history_id` is numeric `payment_link_histories.id`. - name: Virtual Account description: >- Native VA CRUD (`VirtualAccountController`, prefix `v1.0/virtual-accounts`). `account_id` and `virtual_account_id` are ULIDs. - name: VA Transaction description: >- VA money-in transaction listing and detail (`VirtualAccountController`, prefix `v1.0/va-transactions`). - name: QRIS (Money In) description: >- MPM dynamic QRIS list, show, and generate (`QrisMpmDynamicApiController`, prefix `v1.0/qris-dynamic`). - name: QRIS (Money Out) description: >- Issuer MPM decode/inquiry, payment credit (money out), and transaction status (`QrisIssuerMpmController`, `QrisApiV2Controller::checkStatus`, prefix `v2.0/qris`). Related list/detail: `GET /api/v2.0/qris/transaction/...`. - name: E-Wallet (Money In) description: >- E-Wallet Native checkout and transactions (`EwalletNativeApiController`, `EwalletNativeTransactionApiController`, `EwalletNativeV2ApiController`). Paths include `v1.0/ewallet-native`, `v1.0/ewallet-native-transactions`, and `v2.0/ewallet-native`. - name: E-Wallet (Money Out) description: >- E-wallet disbursement / top-up to beneficiary wallets (`EWalletTopUpController`, prefix `v2.0/ewallet`). Responses use the custom **`MerchantV2ApiEnvelope`** with **`MerchantV2ResponseCode`** (SP000–SP020). - name: Card (Money In) description: >- One-time card payment, cancel, and inquiry (`CardPaymentMerchantApiController`, prefix `v2.0/card`). - name: Subscription (Recurring) description: >- Credit-card recurring subscription plans (`SubscriptionPlanApiController`, prefix `v2.0/recurring`). Plan `{id}` is UUID (`sub_plans.id`). - name: Direct Debit description: >- Direct Debit — bind a customer bank account once via hosted webview, then charge it host-to-host (`DirectDebitMerchantController`, prefix `v2.0/direct-debit`). Binding `{binding_id}` and transaction `{transaction_id}` are UUIDs. Responses use the **`MerchantV2ApiEnvelope`** with standard Singapay SP000–SP020 dictionary codes and messages. Field-level validation detail is returned in `data.errors` for **SP018**. The `/charge` endpoint is additionally protected by **`X-Signature`** + **`X-Timestamp`** (`verify.signature-internal`); see operation parameters for the signing scheme. Asynchronous outcomes (bind / unbind / charge) are HTTP POST callbacks to `callback_urls.direct_debit_notif_url` — see the Direct Debit **webhooks** (`directDebitBindingNotification`, `directDebitUnbindingNotification`, `directDebitTransactionNotification`). All three share that single URL; discriminate on `event`. - name: Account Transfer description: >- Move funds between sub-accounts within the same merchant (`AnotherAccountApiController`, prefix `v1.0/account-transfer`). The transfer endpoint requires request signature headers (`verify.signature-internal`). Both accounts must belong to the authenticated merchant and be accessible to the credential. - name: Disbursement (Money Out) description: >- Bank disbursement (`DisbursementController` **v1.0**, `DisbursementV2Controller` **v2.0**). **v1.0** list/show/fee/beneficiary/transfer use Flugg envelopes; v1 inquiry-status uses the **custom v2 envelope** (`MerchantV2ApiEnvelope`, codes **SP000–SP020**). **v2.0** check-beneficiary, transfer, and inquiry-status use the same custom envelope — see component schema **`MerchantV2ResponseCode`** for the full response code table. - name: Cardless Withdrawal description: >- Cardless withdrawal API for initiating ATM cash withdrawals without a physical card. Supports creating withdrawals with OTP generation, listing transaction history, viewing transaction details, canceling pending withdrawals, and deleting canceled records. All endpoints use the `v1.0/cardless-withdrawals` route prefix and the standard success/error response envelope. Path parameter `{id}` refers to the `transaction_id` (platform-assigned business identifier). - name: Retail Store description: >- Native Retail Store money-in — generate an Alfamart / Indomaret payment code the customer pays at the cashier, then read its status (`RetailTransactionController`, prefix `v1.0/retail-transactions`). Only two endpoints: create and show. `account_id` is the account ULID; `transaction_id` is the platform-assigned `retail_transactions.transaction_id` string returned by create. Payment confirmation arrives as a POST callback to `callback_urls.transaction_notif_url` with `event = retail-transaction`. - name: Settlement Transaction description: >- Read-only listing of the transactions inside a settlement (`SettlementMerchantApiController`, `GET v1.0/settlement-transactions/{identifier}`). A sub-menu of the merchant Transaction Record APIs. Merchant-scoped — only settlements with status `completed` are exposed. `{identifier}` is the numeric `settlements.id` or the `settlements.reference_no`. Each item mirrors the money-in transaction shape (`account`, `fees`, `amount`, `post_timestamp`, `processed_timestamp`, `has_settle`, `settle_at`). Merchants cannot create, approve, or refund settlements; those actions are BOSS-only. paths: /api/v2.0/payment-link/{link_id}: get: tags: - Payment Link summary: Show v2 description: >- Retrieves the details of a single payment link. Unlike v1 (scoped under `/{account_id}/{payment_link_id}`), v2 only takes the link id — the owning account is resolved and access-checked from the link itself. operationId: paymentLinkV2Show parameters: - name: link_id in: path required: true schema: description: Payment link identifier (`payment_links.id`). type: integer responses: '200': description: Success content: application/json: schema: $ref: '#/components/schemas/ResponderSuccessPaymentLinkV2' '401': description: Unauthorized content: application/json: schema: $ref: '#/components/schemas/ResponderErrorEnvelope401' '403': description: Access denied to this account content: application/json: schema: $ref: '#/components/schemas/ResponderErrorEnvelope403' '404': description: Payment link not found content: application/json: schema: $ref: '#/components/schemas/ResponderErrorEnvelope404' '405': description: Method not allowed content: application/json: schema: $ref: '#/components/schemas/ResponderErrorEnvelope405' security: - BearerAuth: [] PartnerId: [] components: schemas: ResponderSuccessPaymentLinkV2: required: - status - success properties: status: description: HTTP status code. type: integer example: 200 success: description: Indicates whether the request was successful. type: boolean example: true data: $ref: '#/components/schemas/PaymentLinkV2Resource' description: Payment link resource payload. type: object ResponderErrorEnvelope401: required: - status - success - error properties: status: type: integer example: 401 success: type: boolean example: false error: $ref: '#/components/schemas/ResponderErrorBody401' type: object ResponderErrorEnvelope403: required: - status - success - error properties: status: type: integer example: 403 success: type: boolean example: false error: $ref: '#/components/schemas/ResponderErrorBody403' type: object ResponderErrorEnvelope404: required: - status - success - error properties: status: type: integer example: 404 success: type: boolean example: false error: $ref: '#/components/schemas/ResponderErrorBody404' type: object ResponderErrorEnvelope405: required: - status - success - error properties: status: type: integer example: 405 success: type: boolean example: false error: $ref: '#/components/schemas/ResponderErrorBody405' type: object PaymentLinkV2Resource: description: >- Payment link resource returned by the v2 create/get/update endpoints.
