Affirm checkouts on my store consistently stall at the final confirmation step, and Square transactions intermittently decline without any gateway message. Credit/Debit cards and PayPal look healthy, yet I want every option double-checked so customers have a friction-free experience no matter what they pick. What I need from you: • Trace and resolve the exact bug blocking Affirm orders (API logs show nothing past the authorization call). • Diagnose the Square hiccup, implement the fix, then run at least two successful live $1 tests. • Re-verify Credit/Debit cards and PayPal in the same session to confirm nothing was affected. • Hand me a brief change log and test report so future updates are easier to track. The site already has sandbox credentials for each gateway plus production keys. You’ll get admin access, server logs, and direct contact with our merchant reps if needed. Success is a checkout flow that completes cleanly with Affirm, Square, cards, and PayPal, followed by a concise report summarizing what was changed and proof of passing transactions.
