My tvOS app already uses the Square SDK, but every attempt to charge a card returns a transaction error even though the same code path works on iOS. I need someone who really understands Square’s In-App Payments SDK and tvOS quirks to step into the existing Xcode project, trace the failure, and push a clean, working fix. You will receive a TestFlight build, sandbox credentials and the current repo. Once you pinpoint the problem—whether it’s callback handling, token creation, certificate configuration, or something deeper in the tvOS entitlement—you’ll update the code, rebuild, and demonstrate a successful end-to-end purchase in the Square dashboard. Acceptance criteria • Transactions complete without errors in both sandbox and production modes. • No new crashes, memory leaks, or App Store guideline violations. • A concise changelog and any Square dashboard settings I must replicate in production. When you apply, please only include past work that shows you’ve repaired or implemented payment flows (Square experience on tvOS is a big plus). No need for a long proposal—results speak louder.

Interesting project, I will trace the Square In-App Payments SDK failure in your tvOS Xcode project, isolate whether it is a token creation issue, a callback handling mismatch, or a tvOS entitlement misconfiguration, and push a clean fix. My first step will be comparing the request/response cycle against your working iOS code path, because most tvOS Square failures I have seen come down to subtle differences in how tvOS handles the payment session lifecycle versus iOS. I will verify the fix with a successful end-to-end purchase visible in the Square sandbox dashboard before touching production. You will also get a concise changelog covering any Square dashboard settings you need to replicate. Questions: 1) Is the transaction error you are seeing a specific Square error code, or a generic failure? Looking forward to potentially working together. Thanks, Kamran

This looks like a great fit, We will trace the transaction failure in your tvOS Xcode project, isolate the root cause, and deliver a verified fix with successful charges in both sandbox and production. On tvOS, the most common culprit is how the payment token callback is handled. The SDK delegates behave differently than on iOS because tvOS lacks certain UIViewController lifecycle hooks. We will audit the token creation flow, entitlement configuration, and certificate setup to confirm exactly where the chain breaks. A couple of quick things to confirm: 1) Which Square SDK version is the project using, and has it been updated recently? 2) Does the error return a specific Square error code, or is it a generic transaction failure? The number quoted here is a starting estimate. Looking forward to your response. Best regards, Faizan

Square's tvOS SDK handles the payment flow differently from standard iOS, and transaction errors at charge time usually point to either the location ID being wrong or the payment parameters object not being built correctly for the tvOS target. I can trace the Square API calls in your Xcode project and have this fixed within 2 days. Available to start today. The bid reflects what's in the description. Final numbers depend on what the logs actually show once I'm in the code. Want to jump on a quick call?

Hey — saw your post about fixing the Square payment error on your tvOS app. Payment failures like this often come down to how the transaction requests are structured or authentication tokens are handled. Quick question: Are you using the latest Square SDK version, and have you checked the error codes returned for declined transactions? I’ve integrated Square payments into multiple tvOS projects and know the common pitfalls around transaction setup and token refresh. If you share your current integration code or error logs, I can take a look and help pinpoint the fix.

I understand you're encountering a transaction error with the Square SDK on tvOS, despite the same code functioning on iOS. I've successfully resolved similar platform-specific SDK integration issues, including a recent instance where a tricky certificate configuration prevented payment processing on a connected TV platform. My approach will involve diving into your Xcode project to meticulously trace the payment flow, paying close attention to Square's callback handling and token creation specifically within the tvOS environment. I will leverage Xcode's debugger and the provided TestFlight build and sandbox credentials to pinpoint the exact point of failure, whether it lies in entitlements or a deeper tvOS quirk, and implement a clean, working fix. What specific transaction error code are you observing in the logs when the failure occurs? Ready to start as soon as you confirm scope.

I will thoroughly investigate the existing Xcode project, review the payment flow, callback handling, token generation, entitlements, certificates, and Square configuration to identify the root cause. After implementing the fix, I'll validate successful transactions in both sandbox and production environments, ensure the app remains stable without introducing crashes or memory leaks, and provide a concise changelog along with any required Square dashboard configuration updates. I am available to begin work immediately and am committed to delivering a reliable, production-ready solution in the shortest possible timeframe. I will verify the complete purchase flow end-to-end until transactions are successfully reflected in your Square dashboard. Best regards, Carlos
