Apple Pay: create an Apple Pay merchant session.

POST /api/payment-tokenization/apple-pay/session deprecated

No permission required.

Called by the storefront's `onvalidatemerchant` callback. Proxies the supplied Apple validation URL to Apple over the platform Identity certificate and returns the merchant session payload the browser relays to `ApplePaySession.completeMerchantValidation()`. The validation URL is SSRF-guarded to Apple hosts, and the requested domain must already be verified for the merchant.

Try this in the console

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.

Request body

application/json , required

Field	Type	Description
`providerType` required	WalletProviderType	Defines the supported wallet provider types used for payment tokenization. one of: Unknown, ApplePay, GooglePay, NetworkToken, Paze
`merchantId` required	string (uuid)	Identifier of the merchant the shopper is checking out with. The server reads this merchant's `DigitalWallets[]` to resolve which `WalletProviderRegistration` row to use; the resolution may land on a platform-level row (merchant inherits) or a merchant-level row (merchant brought its own integrator), depending entirely on what the merchant has bound.
`validationUrl` required	string	Provider-supplied validation URL (Apple Pay JS supplies it via `onvalidatemerchant`; the controller MUST NOT substitute it). Conditional: When BeAValidHttpsUrl(ValidationUrl) is true. nullable
`initiativeContext` required	string	Fully-qualified initiating domain. For Apple Pay this is the `initiativeContext`; must be one of the merchant's verified domains. nullablemax length 256

`sessionPayload` required	string	nullable

This response has no documented body fields.

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.

Body: RemoteServiceErrorResponse Each item has these fields.

Field	Type	Description
`error` required	RemoteServiceErrorInfo

This response has no documented body fields.

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.

This response has no documented body fields.
