The API reference isn't available right now

This instance couldn't load its API specification. The reference returns as soon as the specification is readable again.

No such operation

This instance documents no operation under that identifier. It may have been renamed, or it may belong to a feature this installation hasn't enabled.

Back to the API reference

This reference may be out of date

This instance couldn't reach its API specification on the last attempt, so this page shows the copy fetched before that. Anything added or changed since then is missing here, and the reference updates itself as soon as the specification is readable again. Last fetched 2026-10-01 06:30 UTC.

API reference MerchantPaymentEncryptionBinding

Payment encryption: retires one key entry.

POST /api/merchants/{id}/payment-encryption-bindings/{providerName}/keys/{ksi}/deactivate deprecated

Requires: Merchants.Merchants.Update, merchant scope.

Deactivates the entry so it is never matched again. The ordinary end of a key's life: the entry stays readable so a transaction decrypted under it can still be explained, and its key reference stays stored so a reactivation does not need it sent again. Only the status and its timestamp change. Idempotent. Optionally send `If-Match: "<concurrencyStamp>"`.

Example request

Every block below sends the same request. Replace {{BASE_URL}} with the address of the API you are calling and {{API_KEY}} with your own key.

Body: PaymentEncryptionKeyEntry Each item has these fields.

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
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
scheme required all of PaymentEncryptionScheme Which encryption scheme the terminals under this key produce. Required: When Status != Deactivated. nullable
dukptMode required all of PaymentEncryptionDukptMode The DUKPT key derivation algorithm this key uses. nullable
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
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
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
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
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
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
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
status required all of 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
requireMac required boolean Reserved: whether the device family attaches a MAC that should be verified during decryption. nullable
createdAtUtc required string (date-time) When the entry was created, in UTC. nullable
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

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. See the error-code reference in this document's description for the values `error.code` can take.

429 The request was refused because a rate limit was exceeded. 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.

Body: RateLimitProblemDetails Each item has these fields.

Field Type Description
type required string 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 required string A short, human-readable summary of the problem type. nullable
status required integer (int32) The HTTP status code, repeated in the body as the problem-details format defines.
detail required string A human-readable explanation of this occurrence of the problem. nullable
retryAfterSeconds required integer (int32) 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.
