## Request Body

**Content type:** `application/json`

Schema: `AddStoredPaymentMethodInput`

Properties:
- `paymentMethodType` (object): Gets or sets the type of payment method (Card or Check). Conditional: When IsReaderTokenBacked is true. Must equal Card.
- `cardData` (object): Gets or sets the card data when `paymentMethodType` is Card. Required: When PaymentMethodType == Card and IsReaderTokenBacked is false. Conditional: When CardData is not null and PaymentMethodType == Card and IsReaderTokenBacked is false.
- `checkData` (object): Gets or sets the check data when `paymentMethodType` is Check. Required: When PaymentMethodType == Check. Conditional: When CheckData is not null and PaymentMethodType == Check.
- `isDefault` (boolean): Gets or sets whether this should be the customer's default payment method.
- `customName` (string): Gets or sets an optional user-defined display name (e.g., "Marriott Chase").
- `initialSchemeTransactionId` (string): Optional initial (first-in-series) network / scheme transaction id captured from the  authorization response of the cardholder-initiated transaction that stored this credential.  Populated only on the transaction-driven save-card path (the manual Customer admin add has no  authorization response); persisted onto the stored payment method so later charges can echo  it without a consent lookup. Non-sensitive card-network protocol metadata.
- `schemeTransactionIdBrand` (string): Optional card brand at capture time (e.g. "Visa") tagged alongside  `initialSchemeTransactionId`. Ignored when the initial id is absent.
- `schemeTransactionIdProcessor` (string): Optional originating processor ("tsys" / "fiserv") tagged alongside  `initialSchemeTransactionId`. Ignored when the initial id is absent.
- `readerToken` (string): The processor reader token to store for a PAN-less card (a decrypt-and-forward processor such  as MagTek DAF, where the gateway never sees the PAN). When set, this input mints a reader-token  stored method: the token is written encrypted onto the backing vault token's  `ProcessorTokens` and there is no card data to vault. Set by the server only: a value  supplied over the API is not accepted. Never logged.
- `readerTokenProcessorName` (string): The processor key ("magtekdaf") the `readerToken` belongs to, used as the  `ProcessorTokens` selection key. Required when `readerToken` is set. Required: When IsReaderTokenBacked is true.
- `readerTokenProcessorProfileId` (string(uuid)): The processor profile the `readerToken` was captured under, used as the second part  of the `ProcessorTokens` selection key. Optional.
- `readerTokenRequestorId` (string): Optional token-requestor id captured alongside the `readerToken`. Stored on the  backing token's `ProcessorTokens` entry for lineage. Non-sensitive.
- `readerTokenMaskedCardNumber` (string): The masked card number of the card the `readerToken` stands in for, in the  platform's masked shape (for example `411111******1111`), read off the approved  authorization. Optional: absent when the processor response carried no card identity.  Display only. It is never a charge credential and never a dedupe input (two distinct reader  tokens can share a last four; `ReaderTokenFingerprint` stays the only matching key).  The consuming services re-mask it before persisting, so a full PAN cannot travel through  this field. Ignored unless `readerToken` is set.
- `readerTokenCardBrand` (string): The card brand ("Visa", "Mastercard", ...) resolved for the card behind the  `readerToken`, or `null` when neither the processor response nor  the BIN lookup produced one. Best-effort display metadata; ignored unless  `readerTokenMaskedCardNumber` is set.
- `isReaderTokenBacked` (boolean): True when this input describes a reader-token (PAN-less) stored method rather than a  PAN- or account-backed one. In that case `cardData` is absent by design.

_Example: Add Card_

Adds a credit/debit card to the customer's stored payment methods. Set IsDefault = true to mark this as the customer's default payment method (any prior default is automatically demoted server-side).

## Responses

### 200

OK

**Content type:** `application/json`

Schema: `CustomerStoredPaymentMethodDto`

Properties:
- `extraProperties` (object)
- `id` (string(uuid))
- `creationTime` (string(date-time)): The date and time when this entity was created.
- `creatorId` (string(uuid)): The ID of the user who created this entity.
- `lastModificationTime` (string(date-time)): The date and time when this entity was last modified.
- `lastModifierId` (string(uuid)): The ID of the user who last modified this entity.
- `isDeleted` (boolean): Indicates whether this entity has been deleted.
- `deleterId` (string(uuid)): The ID of the user who deleted this entity, if it is deleted.
- `deletionTime` (string(date-time)): The date and time when this entity was deleted, if it is deleted.
- `tenantId` (string(uuid)): Id of the related tenant.
- `concurrencyStamp` (string): Gets or sets the concurrency stamp used for optimistic concurrency control.
- `entityVersion` (integer(int32)): A version value that is increased whenever the entity is changed.
- `paymentMethodType` (object): Gets or sets the type of stored payment method (card, check, etc.).
- `cardData` (object): Gets or sets the card data when `paymentMethodType` is `Card`.
- `checkData` (object): Gets or sets the check/ACH data when `paymentMethodType` is `Check`.
- `isDefault` (boolean): Gets or sets a value indicating whether this is the customer's default payment method.
- `displayName` (string): Gets the human-readable display name for this payment method. When `customName`  is set, it takes priority over the computed brand + last-4 fallback.
- `customName` (string): Gets or sets an optional user-defined name for this payment method  (e.g., "Marriott Chase", "Bank of America Checkcard").
- `paymentTokenId` (string(uuid)): Gets or sets the identifier of the `PaymentToken` document that stores  the encrypted card/check data for this stored payment method.
- `publicReference` (string): Gets or sets the chargeable public reference (the opaque `pt_`-prefixed handle) of the  backing `PaymentToken`.
- `origin` (object): Gets or sets the surface / add-channel this stored payment method was captured through  (manual admin, hosted payment page, virtual terminal, or API). Null when the method predates  this field, which callers treat as `Unknown`.  Non-sensitive add-channel metadata.
- `isReaderTokenBacked` (boolean): Gets or sets whether this stored method is backed by a processor card token rather than a  stored card number: the card was captured by a card reader on a decrypt-and-forward processor,  so the platform never held its number and the method carries no expiration date. Such a method  is charged through its `publicReference` exactly like any other, but only on the  processor that issued the token. `false` for every card-number-backed card and  every bank account method.

Internal Server Error

**Content type:** `application/json`

Schema: `RemoteServiceErrorResponse`

Properties:
- `error` (RemoteServiceErrorInfo)

### 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.

**Content type:** `application/json`

Schema: `RemoteServiceErrorResponse`

Properties:
- `error` (RemoteServiceErrorInfo)

### 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`

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.
- `title` (string) required: A short, human-readable summary of the problem type.
- `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.
- `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`

Properties:
- `error` (RemoteServiceErrorInfo)
