In the scenario described, where an E-commerce site hosts multiple merchants and utilizes a single domain for checkout, there are several factors to consider regarding the registration process for Apple Pay on the Web. Single Domain Checkout Site Registration: Since all merchants utilize the same checkout URL on the single domain E-commerce site, it's feasible to register this domain as an Apple ID merchant and manage the "JS" and backend parts of Apple Pay on the Web. This centralized approach simplifies management by requiring only one set of certificates. Merchant Registration: While technically feasible to have merchants bypass individual registration for Apple Pay on the Web, it's important to consider potential implications. Apple may have specific guidelines or requirements regarding merchant registration, and bypassing this process could lead to issues with compliance or functionality down the line. Compliance and Guidelines: It's advisable to thoroughly review Apple's guidelines and documentation regarding Apple Pay on the Web to ensure compliance with their requirements. While the solution may work technically without requiring individual merchant registration, adherence to Apple's guidelines is essential for a seamless and compliant integration. Payment Gateway Integration: The involvement of a payment gateway for the final authorization step adds another layer to consider. Ensure that the payment gateway supports Apple Pay on the Web and that the merchant profile contains the necessary identifiers for seamless transaction processing. In summary, while the technical feasibility of managing Apple Pay on the Web through a single domain E-commerce Agency https://myteamz.co.uk/ site without requiring individual merchant registration may seem attractive, it's crucial to thoroughly review Apple's guidelines and consider potential compliance implications. Maintaining compliance and adhering to best practices will ultimately contribute to a smooth and successful integration of Apple Pay on the Web for all merchants involved.

It seems you are on the right track but are encountering a specific issue with Xcode's handling of self-signed certificates. Here are some steps to troubleshoot and potentially resolve the problem: Ensure Certificate Trust Settings: Verify that both the root CA "Dev Authority" and the leaf certificate "Testing 123" are trusted for code signing in Keychain Access. Open Keychain Access. Find "Dev Authority", right-click, and select "Get Info". Go to the "Trust" section and set "Code Signing" to "Always Trust". Do the same for the "Testing 123" certificate. Verify Key Usage Extensions: Ensure that the leaf certificate has the appropriate key usage extensions for code signing. Open Keychain Access. Find "Testing 123", right-click, and select "Get Info". Check under the "Details" tab to see if it includes "Digital Signature" under "Key Usage" and "Code Signing" under "Extended Key Usage". Check Certificate Validity Period: Ensure that the certificate is valid for the current date and has not expired. This can be checked in the "Details" tab of the certificate's info in Keychain Access. Certificate Chain: Ensure that the certificate chain is correctly recognized by macOS. Open Keychain Access. Go to the "System" keychain and make sure both "Dev Authority" and "Testing 123" are present there. Ensure that the "Testing 123" certificate correctly shows "Dev Authority" as its issuer. Check Organizational Unit (OU): Sometimes, the Organizational Unit (OU) needs to be set in a certain way for Xcode to accept the certificate. Open Keychain Access. Find "Testing 123", right-click, and select "Get Info". Ensure that the "Organization Unit" field is filled out and matches the "Organization Unit" of "Dev Authority". Revocation Checks: Disable online certificate revocation checks temporarily to see if it resolves the issue. Open Terminal and run the following command: defaults write com.apple.security.revocation OCSPStyle NoCheck defaults write com.apple.security.revocation CRLStyle NoCheck Note: This is not recommended for production use as it can reduce security. Xcode Settings: Sometimes, Xcode caches certain settings. Try cleaning the build folder and resetting Xcode's code signing settings. In Xcode, go to "Product" > "Clean Build Folder". In Xcode, go to "Xcode" > "Preferences" > "Accounts" and refresh your developer account. Manual Signing in Xcode: Double-check the manual signing settings. Go to your project's settings in Xcode. Under the "Signing & Capabilities" tab, ensure "Automatically manage signing" is disabled. Select "Testing 123" as the signing certificate manually. If the issue persists after these steps, it may be helpful to use the codesign command in the terminal to get more verbose information about the failure: codesign -vvv -d /path/to/your/app This should provide detailed output about the code signature and might help identify why Xcode is rejecting the certificate. If none of these steps resolve the issue, there may be an underlying restriction in Xcode regarding self-signed certificates. In that case, reaching out to Apple Developer Support might provide additional insights. Edit: https://canapeking.co.uk/collections/palm-leaf
