# GET /api/merchants/{id}/payment-encryption-bindings Payment encryption: lists the merchant's provider bindings. Example: `GET /api/merchants/3fa85f64-5717-4562-b3fc-2c963f66afa6/payment-encryption-bindings`. **Operation ID:** `merchantPaymentEncryptionBindingGetPaymentEncryptionBindingList` ## Authorization Requires: Merchants.Merchants, merchant scope. Requires API key scope: `admin` Required permissions: - `Merchants.Merchants` ## Parameters | Name | In | Required | Type | Description | | --- | --- | --- | --- | --- | | id | path | yes | string(uuid) | The merchant id. | | suppressNulls | query | no | boolean | If true, omit properties with null values. | ## Responses ### 200 OK **Content type:** `application/json` Schema type: `array<[MerchantPaymentEncryptionBinding](https://devportal.signapay-sbx.winkpg.io/docs/api/models/MerchantPaymentEncryptionBinding.md)>` Item properties: - `providerName` (string): Which payment encryption provider this entry binds the merchant to, by the provider's registered name. Compared case-insensitively. A null or blank provider is treated as no binding at all, so an incompletely boarded row cannot silently become a live selection. Required: When IsEnabled is true. (nullable, max length 64) - `isEnabled` (boolean): Master enable flag for this provider on this merchant. When `false` or null, the selector must not return this binding even though the row exists. (nullable) - `credentialSource` ([PaymentEncryptionCredentialSource](https://devportal.signapay-sbx.winkpg.io/docs/api/models/PaymentEncryptionCredentialSource.md)): Whose provider account the decryption calls are billed to. Null reads as `Gateway`. (nullable) Values: - `Gateway`: The gateway's own provider account. The binding stores no credential of its own: the values are filled in at read time from the host-scoped provider settings, and the merchant surfaces never carry them. This is what a null credentialSource reads as, which is the safe default: a half-completed row cannot accidentally claim to hold the merchant's own contract. - `Merchant`: The merchant's own provider account. The binding carries the credentials, with every secret value held as ciphertext and stripped on any read that leaves the server. - `fieldValues` (array<[PaymentEncryptionBindingFieldValue](https://devportal.signapay-sbx.winkpg.io/docs/api/models/PaymentEncryptionBindingFieldValue.md)>): The provider-declared configuration values for this merchant, keyed by the setting names the provider declares. Secret values are stored encrypted and are stripped, not decrypted, on every read that leaves the server. Only the server-side call to the provider ever uses the plaintext. Empty for a `Gateway` binding, whose values are filled in at read time from the host-scoped provider settings instead. A gateway-sourced row that carried values would be a copy of the gateway's credentials living on a merchant document. Conditional: When FieldValues is not null. (nullable) Fields of each item: - `key` (string): The provider setting name this value belongs to, matching a `PaymentEncryptionSettingFieldDefinition.SettingName` the provider's contributor declares. Compared case-insensitively. (nullable) - `value` (string): The configured value. Ciphertext at rest whenever `isSecret` is `true`, and `null` on every read that leaves the server. (nullable) - `isSecret` (boolean): Whether `value` is credential material, and so held encrypted and stripped on read. (nullable) - `isConfigured` (boolean): Whether a secret value is stored, set on reads so an operator can tell a configured secret from an empty one without the value ever being sent. (nullable) - `keyEntries` (array<[PaymentEncryptionKeyEntry](https://devportal.signapay-sbx.winkpg.io/docs/api/models/PaymentEncryptionKeyEntry.md)>): The key serial identifier entries that map an inbound key serial number to an HSM key. Conditional: When KeyEntries is not null. (nullable) Fields of each item: - `ksi` (string) required: The key serial identifier: six to ten significant hex characters, stored upper-case with leading `F` padding stripped. Unique within a binding. Conditional: When Ksi is not empty. (nullable) - `label` (string): An operator-facing label for this key, such as the device family it was injected into. Shown wherever the key reference itself must not be. (nullable, max length 100) - `scheme` ([PaymentEncryptionScheme](https://devportal.signapay-sbx.winkpg.io/docs/api/models/PaymentEncryptionScheme.md)): Which encryption scheme the terminals under this key produce. Required: When Status != Deactivated. (nullable) Values: - `Dukpt`: Generic DUKPT (ANSI X9.24 data variant), TDES or AES. - `OnGuard`: The Ingenico On-Guard protocol. - `dukptMode` ([PaymentEncryptionDukptMode](https://devportal.signapay-sbx.winkpg.io/docs/api/models/PaymentEncryptionDukptMode.md)): The DUKPT key derivation algorithm this key uses. (nullable) Values: - `Tdes`: Triple DES DUKPT (ANSI X9.24 Part 1). - `Aes`: AES DUKPT (ANSI X9.24 Part 3). Carries a working-key type alongside it. - `aesWorkingKeyType` (string): The AES working-key type, required when `dukptMode` is `Aes` and meaningless otherwise. A provider token value rather than an enum, because the vocabulary belongs to the vendor's command set. Required: When DukptMode == Aes. Conditional: When DukptMode is not null and DukptMode != Aes. (nullable, max length 16) - `keyReference` (string): The HSM key reference: a storage-table slot or a wrapped key block. Always stored encrypted, and never returned on a read that leaves the server. (nullable, max length 1024) - `isKeyReferenceConfigured` (boolean): Whether a key reference is stored, set on reads so an operator can tell a configured key from an empty one without the reference ever being sent. Server-owned: the save paths ignore whatever arrives here. (nullable) - `majorKey` (string): The major key the reference is stored under, in the provider's own token vocabulary. Null leaves the provider's default in force. (nullable, max length 16) - `onGuardExtendedEncryption` (boolean): On-Guard extended encryption, when the device family uses it. Meaningful only when `scheme` is `OnGuard`. Conditional: When Scheme is not null and Scheme != OnGuard. (nullable) - `onGuardEndingPanDigitsEncrypted` (boolean): Whether the device family encrypts the ending PAN digits. Meaningful only for `OnGuard`. Conditional: When Scheme is not null and Scheme != OnGuard. (nullable) - `onGuardClearPanDigits` (integer(int32)): How many leading PAN digits the device family leaves in the clear. Meaningful only for `OnGuard`. Conditional: When Scheme is not null and Scheme != OnGuard. Conditional: When OnGuardClearPanDigits is not null. Range: 0 to 6. (nullable) - `status` ([PaymentEncryptionKeyEntryStatus](https://devportal.signapay-sbx.winkpg.io/docs/api/models/PaymentEncryptionKeyEntryStatus.md)): Whether the entry may be matched. Null reads as `Deactivated`: an entry whose status nobody set has not been through the boarding step that activates it, and matching it would use a key the platform cannot confirm is live. (nullable) Values: - `Active`: The entry may be matched against an inbound key serial number. - `Deactivated`: The entry is retired. It stays readable for explaining past transactions, and is never matched. - `requireMac` (boolean): Reserved: whether the device family attaches a MAC that should be verified during decryption. (nullable) - `createdAtUtc` (string(date-time)): When the entry was created, in UTC. (nullable) - `statusChangedAtUtc` (string(date-time)): When `status` last changed, in UTC. Separate from the audit log because it is shown on the key table itself, where an operator decides whether a key is still in rotation. (nullable) - `primaryEndpoint` (string): The primary provider endpoint for this merchant, or null to use the provider's own configured endpoint. HTTPS-only, enforced by the binding validator. Conditional: When PrimaryEndpoint is not empty. (nullable, max length 512) - `secondaryEndpoint` (string): The secondary provider endpoint, used when the primary does not answer. HTTPS-only. Null when the merchant is bound to one region only. Conditional: When SecondaryEndpoint is not empty. Conditional: When SecondaryEndpoint is not empty and PrimaryEndpoint is empty. (nullable, max length 512) - `decryptTimeoutMillisecondsOverride` (integer(int32)): A per-merchant override of the gateway-wide decryption budget, in milliseconds, or null to use the gateway setting. Conditional: When DecryptTimeoutMillisecondsOverride is not null. Range: 250 to 30000. (nullable) ### 429 The request was refused because a rate limit was exceeded, or because something a later retry can clear stopped it. A rate limit refusal carries an `application/problem+json` body: wait at least the interval `Retry-After` names before retrying, then back off. Limits are tuned per deployment, so read the allowance from the response headers rather than assuming a fixed ceiling. Any other refusal carries the standard error envelope as `application/json`, and its `error.code` names the cause. **Content type:** `application/problem+json` Schema: [`RateLimitProblemDetails`](https://devportal.signapay-sbx.winkpg.io/docs/api/models/RateLimitProblemDetails.md) Properties: - `type` (string) required: The problem type identifier. Always the same value: the failure is the status code itself, so there is no sub-type for a caller to branch on. (nullable) - `title` (string) required: A short, human-readable summary of the problem type. (nullable) - `status` (integer(int32)) required: The HTTP status code, repeated in the body as the problem-details format defines. - `detail` (string) required: A human-readable explanation of this occurrence of the problem. (nullable) - `retryAfterSeconds` (integer(int32)) required: How long to wait before retrying, in whole seconds, carrying the same figure as the `Retry-After` header. Always at least one: a value of zero would invite an immediate retry that is certain to be rejected again. **Content type:** `application/json` Schema: [`RemoteServiceErrorResponse`](https://devportal.signapay-sbx.winkpg.io/docs/api/models/RemoteServiceErrorResponse.md) Properties: - `error` ([RemoteServiceErrorInfo](https://devportal.signapay-sbx.winkpg.io/docs/api/models/RemoteServiceErrorInfo.md)) ### 400 Bad request. The request was malformed or failed validation. When validation rejected it, `error.validationErrors` names each member at fault and why. **Content type:** `application/json` Schema: [`RemoteServiceErrorResponse`](https://devportal.signapay-sbx.winkpg.io/docs/api/models/RemoteServiceErrorResponse.md) Properties: - `error` ([RemoteServiceErrorInfo](https://devportal.signapay-sbx.winkpg.io/docs/api/models/RemoteServiceErrorInfo.md)) _Example: Request failed validation_ One or more fields were rejected before any rule ran. error.code is null on the envelope and the causes are in validationErrors, one entry per failure. An entry carries code when the validator declared a publishable one, and memberPaths when the full path says more than members does (an element inside a collection, for example). Both keys are omitted when they would add nothing. ```json { "error": { "code": null, "message": "Your request is not valid!", "details": "The following errors were detected during validation.", "data": { "correlationId": "0123456789abcdef0123456789abcdef" }, "validationErrors": [ { "message": "'Amount' must be greater than 0.", "members": [ "amount" ] }, { "message": "The card has expired.", "members": [ "expirationDate" ], "code": "CardData:CardExpired" }, { "message": "'Value' must not be empty.", "members": [ "value" ], "memberPaths": [ "customFields[2].value" ] } ] } } ``` ### 401 Unauthorized. The request carried no API key or signed-in session, or the key it carried is invalid, revoked or expired. **Content type:** `application/json` Schema: [`RemoteServiceErrorResponse`](https://devportal.signapay-sbx.winkpg.io/docs/api/models/RemoteServiceErrorResponse.md) Properties: - `error` ([RemoteServiceErrorInfo](https://devportal.signapay-sbx.winkpg.io/docs/api/models/RemoteServiceErrorInfo.md)) ### 403 Forbidden. The API key lacks the scope this operation needs, the signed-in user lacks the permission, or a business rule refused the request. The error code in the body names the reason. **Content type:** `application/json` Schema: [`RemoteServiceErrorResponse`](https://devportal.signapay-sbx.winkpg.io/docs/api/models/RemoteServiceErrorResponse.md) Properties: - `error` ([RemoteServiceErrorInfo](https://devportal.signapay-sbx.winkpg.io/docs/api/models/RemoteServiceErrorInfo.md)) ### 404 Not found. The resource the request names does not exist or is not visible to the caller: a resource that belongs to a merchant or tenant outside the caller's scope is reported as not found. **Content type:** `application/json` Schema: [`RemoteServiceErrorResponse`](https://devportal.signapay-sbx.winkpg.io/docs/api/models/RemoteServiceErrorResponse.md) Properties: - `error` ([RemoteServiceErrorInfo](https://devportal.signapay-sbx.winkpg.io/docs/api/models/RemoteServiceErrorInfo.md)) _Example: Resource not found_ The id in the path names no record the caller can see. Most resources answer with a null error.code and a message naming the resource type and the id; a resource that publishes a not-found code in the catalog above carries it in error.code instead, so check for one before matching on the message. ```json { "error": { "code": null, "message": "There is no entity Transaction with id = 7d1f3a52-0c4e-4b8a-9e21-5a6b7c8d9e00!", "details": null, "data": { "correlationId": "0123456789abcdef0123456789abcdef" }, "validationErrors": null } } ``` ### 500 Internal server error. The platform failed unexpectedly while handling the request. If it keeps failing, contact support and quote the correlation id, which the response carries in the `X-Correlation-Id` header and as `error.data.correlationId`. **Content type:** `application/json` Schema: [`RemoteServiceErrorResponse`](https://devportal.signapay-sbx.winkpg.io/docs/api/models/RemoteServiceErrorResponse.md) Properties: - `error` ([RemoteServiceErrorInfo](https://devportal.signapay-sbx.winkpg.io/docs/api/models/RemoteServiceErrorInfo.md)) ### 501 Not implemented. The operation is declared but has no implementation on this deployment, so no request to it can succeed. Retrying does not help. **Content type:** `application/json` Schema: [`RemoteServiceErrorResponse`](https://devportal.signapay-sbx.winkpg.io/docs/api/models/RemoteServiceErrorResponse.md) Properties: - `error` ([RemoteServiceErrorInfo](https://devportal.signapay-sbx.winkpg.io/docs/api/models/RemoteServiceErrorInfo.md)) ### default The request failed. The body carries the standard error envelope: a machine-readable `error.code`, a human-readable `error.message`, and `error.validationErrors` when the failure was a validation rejection. The [error reference](https://devportal.signapay-sbx.winkpg.io/docs/errors.md) lists the values `error.code` can take. **Content type:** `application/json` Schema: [`RemoteServiceErrorResponse`](https://devportal.signapay-sbx.winkpg.io/docs/api/models/RemoteServiceErrorResponse.md) Properties: - `error` ([RemoteServiceErrorInfo](https://devportal.signapay-sbx.winkpg.io/docs/api/models/RemoteServiceErrorInfo.md)) _Example: Business rule refused the request_ The request was understood and rejected by a platform rule. This is the shape that carries a code from the catalog above, so branch on error.code rather than on the message text. The HTTP status is the one listed against the code. ```json { "error": { "code": "Transactions:OperationNotAllowed", "message": "The operation 'Void' is not allowed on a Sale transaction with result 'Approved' and settlement state 'Settled'.", "details": null, "data": { "correlationId": "0123456789abcdef0123456789abcdef" }, "validationErrors": null } } ``` ### Errors These statuses answer with the error envelope outlined below. - `400`: Bad request. The request was malformed or failed validation. When validation rejected it, `error.validationErrors` names each member at fault and why. - `401`: Unauthorized. The request carried no API key or signed-in session, or the key it carried is invalid, revoked or expired. - `403`: Forbidden. The API key lacks the scope this operation needs, the signed-in user lacks the permission, or a business rule refused the request. The error code in the body names the reason. - `404`: Not found. The resource the request names does not exist or is not visible to the caller: a resource that belongs to a merchant or tenant outside the caller's scope is reported as not found. - `500`: Internal server error. The platform failed unexpectedly while handling the request. If it keeps failing, contact support and quote the correlation id, which the response carries in the `X-Correlation-Id` header and as `error.data.correlationId`. - `501`: Not implemented. The operation is declared but has no implementation on this deployment, so no request to it can succeed. Retrying does not help. - `default`: The request failed. The body carries the standard error envelope: a machine-readable `error.code`, a human-readable `error.message`, and `error.validationErrors` when the failure was a validation rejection. The [error reference](https://devportal.signapay-sbx.winkpg.io/docs/errors.md) lists the values `error.code` can take. **Content type:** `application/json` Schema: [`RemoteServiceErrorResponse`](https://devportal.signapay-sbx.winkpg.io/docs/api/models/RemoteServiceErrorResponse.md) Properties: - `error` ([RemoteServiceErrorInfo](https://devportal.signapay-sbx.winkpg.io/docs/api/models/RemoteServiceErrorInfo.md)) Fields: - `code` (string): (nullable) - `message` (string): (nullable) - `details` (string): (nullable) - `data` (object): (nullable) - `validationErrors` (array<[RemoteServiceValidationErrorInfo](https://devportal.signapay-sbx.winkpg.io/docs/api/models/RemoteServiceValidationErrorInfo.md)>): (nullable) _Example: Request failed validation_ One or more fields were rejected before any rule ran. error.code is null on the envelope and the causes are in validationErrors, one entry per failure. An entry carries code when the validator declared a publishable one, and memberPaths when the full path says more than members does (an element inside a collection, for example).
