# Apple Pay Web Merchant Registration API Manage merchant registration through your web platform. ## Overview The Apple Pay Web Merchant Registration API is a REST API that enables platform integrators such as payment-service providers and e-commerce platforms to register web merchants who want to offer Apple Pay on the web. As a platform integrator, you manage Apple Pay configuration on the merchants’ behalf when you call [`Register Merchant`](/documentation/ApplePayWebMerchantRegistrationAPI/Register-Merchant). Merchants aren’t required to set up an Apple Developer account or configure their own keys and certificates — you set up a shared set of keys and certificates for your entire merchant portfolio. Register merchants with their own website domains, or with web pages hosted by your platform. > Note: > This API is available in production and in sandbox environments. To use this API in the sandbox environment, call the endpoints using the domain `apple-pay-gateway-cert.apple.com`. For example, the sandbox endpoint for ``doc://com.apple.applepaywebmerchantregistrationapi/documentation/ApplePayWebMerchantRegistrationAPI/Register-Merchant`` is: `POST https://apple-pay-gateway-cert.apple.com/paymentservices/registerMerchant`. ### API Requirements for Use To use the Apple Pay Web Merchant Registration API, you must meet the following requirements: - Your organization must be enrolled in the Apple Developer program.
