Body: array of MerchantPaymentEncryptionBinding array of MerchantPaymentEncryptionBinding Each item has these fields.

Field Type Description
providerName required 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. nullablemax length 64
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
isEnabled required 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
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
credentialSource required PaymentEncryptionCredentialSource PaymentEncryptionCredentialSource Whose provider account the decryption calls are billed to. Null reads as `Gateway`. nullable
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
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 required array of PaymentEncryptionBindingFieldValue array of PaymentEncryptionBindingFieldValue The provider-declared configuration values for this merchant, keyed by the setting names the provider declares. <b>Secret values are stored encrypted</b> 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
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

Fields of each PaymentEncryptionBindingFieldValue:

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
value required string The configured value. Ciphertext at rest whenever `isSecret` is `true`, and `null` on every read that leaves the server. nullable
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
isSecret required boolean Whether `value` is credential material, and so held encrypted and stripped on read. nullable
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
isConfigured required 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
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

This body has no documented fields.

keyEntries required array of PaymentEncryptionKeyEntry array of PaymentEncryptionKeyEntry The key serial identifier entries that map an inbound key serial number to an HSM key. Conditional: When KeyEntries is not null. nullable
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

Fields of each PaymentEncryptionKeyEntry:

Field Type Description
ksi required string 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
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
label required 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. nullablemax length 100
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
scheme required PaymentEncryptionScheme PaymentEncryptionScheme Which encryption scheme the terminals under this key produce. Required: When Status != Deactivated. nullable
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
Dukpt Generic DUKPT (ANSI X9.24 data variant), TDES or AES.
OnGuard The Ingenico On-Guard protocol.
dukptMode required PaymentEncryptionDukptMode PaymentEncryptionDukptMode The DUKPT key derivation algorithm this key uses. nullable
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
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 required 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. nullablemax length 16
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
keyReference required string The HSM key reference: a storage-table slot or a wrapped key block. <b>Always stored encrypted, and never returned on a read that leaves the server.</b> nullablemax length 1024
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
isKeyReferenceConfigured required 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
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
majorKey required string The major key the reference is stored under, in the provider's own token vocabulary. Null leaves the provider's default in force. nullablemax length 16
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
onGuardExtendedEncryption required 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
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
onGuardEndingPanDigitsEncrypted required boolean Whether the device family encrypts the ending PAN digits. Meaningful only for `OnGuard`. Conditional: When Scheme is not null and Scheme != OnGuard. nullable
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
onGuardClearPanDigits required 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
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
status required PaymentEncryptionKeyEntryStatus PaymentEncryptionKeyEntryStatus 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: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
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 required boolean Reserved: whether the device family attaches a MAC that should be verified during decryption. nullable
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
createdAtUtc required string (date-time) When the entry was created, in UTC. nullable
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
statusChangedAtUtc required 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
Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.

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.
