I need expert help tracking down and fixing an Apple Pay error that blocks our users the moment they hit payment authorisation. Apple Pay returns “” "not registered for service" with response code 417. across every device we have tested, so the problem is clearly in our implementation rather than on a single phone or browser. The integration sits inside the EveryAction payment platform. I already confirmed our merchant ID, domain verification file, and certificates are live, yet the authorisation step still fails. What I’m after is a clean code-level repair, a concise write-up of what went wrong, and proof the fix works on real hardware (at minimum iPhone with Safari and a recent Mac with Safari). NOTE: you must have your own iPhone in order to be eligible to work on this project! The only way for you to determine whether or not the error is fixed is if you test it on your own iPhone. Deliverables: • Updated code or configuration that eliminates the “Invalid payment request” response during authorisation. • Short technical summary of the root cause and the exact changes made. • Screenshots or screen recordings demonstrating a successful Apple Pay transaction on at least two different devices. If you have deep experience with Apple Pay JS / Payment Request API, can test quickly, and are comfortable working inside the EveryAction environment, I’d love to get this resolved today.

Hi, I can help you with that Apple Pay error. The 'not registered for service' with code 417 typically means the merchant validation request is hitting the wrong endpoint or the session object isn't structured right for the EveryAction environment. I've debugged Payment Request API issues on real iPhones many times and I have my own iPhone and Mac here to test. I'll get your auth working, document the root cause, and send you proof across two devices. I'm Edward, been doing this kind of deep JS integration work for years. Let me know if you want to discuss.

Hi, This is the kind of Apple Pay issue that needs hands-on debugging, not guesswork. Since the same 417 "not registered for service" error appears across devices, I would treat it as an implementation, merchant validation, configuration, or EveryAction payment request issue. I have experience with JavaScript payment integrations, Apple Pay JS, Payment Request API, domain validation, merchant session validation, certificates, and API debugging. I can review the full Apple Pay flow, inspect the merchant validation request, payment request payload, domain association, supported networks, merchant capabilities, certificate chain, and EveryAction-specific configuration to find exactly where authorization is failing. Once fixed, I can provide updated code or configuration, a concise technical summary of the root cause, and real-device proof of successful Apple Pay authorization using Safari on iPhone and Mac. I can work carefully inside your existing EveryAction setup and focus on resolving the issue quickly without disrupting the rest of the payment flow. Best, Justin

Hi there, You’re right that a 417 “not registered for service” across all devices strongly suggests an implementation / configuration issue rather than device-specific. I can help you isolate and fix this at the Apple Pay JS / Payment Request API layer. Here’s what I’ll handle: • Review your Apple Pay setup inside EveryAction (merchant ID, payment session, domain association, headers, payment request fields). • Identify and fix the exact cause of the “Invalid payment request” / 417 response (code or configuration). • Provide a short technical write-up of root cause and the precise changes made. • Test and document successful transactions with screenshots/screen recordings from my own iPhone (Safari) and a recent Mac with Safari. I’ve spent years debugging payment flows and API integrations in JavaScript-based frontends and backend services, including strict verification and payment-like flows (e.g., ShuftiPro KYC platform) where small config issues cause hard-to-diagnose failures. I’m used to working inside third‑party environments and tracking down subtle misconfigurations and request/response issues. If you can share temporary access to the EveryAction environment, current Apple Pay configuration, and a test card / sandbox details, I can start right away and aim to get this resolved today.

Hello, I have carefully read your requirements, and it would be an honor to help diagnose and resolve the Apple Pay authorization issue. With 14+ years of experience in payment gateway integrations, web development, and troubleshooting complex production issues, I can perform a detailed review of your Apple Pay implementation, EveryAction configuration, merchant validation flow, payment request structure, certificates, domain association, and authorization process to identify the root cause of the 417 "not registered for service" error. I understand that merchant IDs, certificates, and domain verification may already be configured correctly, which often means the issue lies within the payment request payload, merchant session validation, gateway configuration, or platform-specific integration settings. My approach includes reviewing logs, reproducing the issue, validating Apple Pay JS requests, testing the authorization workflow, and implementing the required code or configuration fixes to restore successful transactions. I will provide a concise technical report detailing the root cause, the exact changes made, and verification results after testing. If access to physical Apple devices is required for final validation, I can coordinate testing accordingly and document the results. Please check my profile to review my ratings, client feedback, and previous payment integration and troubleshooting projects. Warm Regards, Harpreet Singh

`Hi! Response code 417 with "not registered for service" inside EveryAction almost always points to a mismatch between the merchant session validation request and the domain registered in Apple's developer portal — even when the domain verification file and certificates appear correct. The session validation URL, initiative context, and display name must match exactly what Apple has on file, and EveryAction sometimes overrides these silently. I'll audit the full Apple Pay JS flow, fix the authorisation handshake at code level, and verify the fix with live transactions on iPhone with Safari and Mac with Safari, providing screenshots as proof. A clear technical write-up of root cause and changes made is included. Looking forward to resolving this for you today!

Hi there! I understand you are facing a critical Apple Pay error that is blocking users at the final payment step, which directly impacts conversions and revenue. This kind of “not registered for service” (417) issue usually points to a deeper misconfiguration in Apple Pay JS or merchant validation inside the payment flow, even when certificates and domain verification look correct. I have strong experience working with Apple Pay JS, Payment Request API, and debugging payment gateway integrations in production environments. I have fixed similar issues where merchant validation, session handling, or platform-specific constraints (like EveryAction setups) were causing silent failures during authorization. My approach will be to first replicate and isolate the exact failure point in the authorization flow. Then I will review your merchant session setup, domain association, and payment request structure to identify the mismatch. After that, I will implement a clean fix in code or configuration and validate it directly on real devices. Finally, I will document the root cause clearly so you can avoid it in future updates. check our work https://www.freelancer.com/u/ayesha86664 Have you already checked whether the Apple Pay session merchant validation callback is completing successfully in logs? Let me know if you’re interested & we can discuss it. Best Regards Ayesha
