PayPal API Jobs

I own the existing site at and need it rebuilt under the new domain thepopuptournaments.com. The core concept stays the same—organising popup pickleball tournaments—but several features must be repaired or expanded while we keep only minor design tweaks in mind. Key deliverables • Round-robin engine: adjust the current match-making logic so every player meets any given opponent no more than twice during round-robin play. • Payments: integrate a Stripe credit-card checkout flow tied to each event registration. Players should be charged automatically once their spot is confirmed, with basic refund handling in the dashboard. • Email validation: block invalid or disposable email addresses at sign-up and during any profile edits, both client- and server-side. ...

Payments on my store are intermittently failing at the PayPal checkout stage—customers see an error after clicking “Pay Now” and the order never records in the system. Everything else on the site runs smoothly, so the issue is isolated to the payment flow. I need a developer who understands the PayPal REST API, IPN/webhooks and typical WooCommerce-style (PHP) integrations to: • trace where the transaction breaks, • restore reliable authorisation and capture, and • test live and sandbox modes to confirm stability. Please be comfortable working on a live e-commerce environment, backing up before touching core files or gateway settings, and providing a concise summary of what was fixed so I can maintain it going forward.

I’ve already launched several apps and now want to let customers pre-pay for usage by buying a bundle of tokens on my Squarespace site, with Stripe handling the checkout. After purchase, those tokens should immediately appear on the customer’s account inside each of my published apps, where they’ll be debited as the user consumes features. Here’s the flow I have in mind: 1. Visitor selects a token amount on a Squarespace 'buy credits' page and pays once through Stripe Checkout or Payment Links. 2. A secure webhook or custom API call translates that successful payment into an updated token balance in my backend. 3. When the balance is refreshed the user can start spending tokens without delay. 4. When the user tries to use one of the online tools (AI gener...

I’m ready to upgrade my website with real-time flight and hotel booking and to process every transaction through PayU. The site already has a basic front-end; what it needs now is solid back-end wiring to a travel API and a seamless PayU checkout flow.

The flow should: 1. create an order from the travel API response, 2. hand off to PayU’s checkout (redirect or embedded), 3. handle webhooks/callbacks for success, failure, or refund, and 4. update my database and send confirmation emails automatically. Deliverables • Fully functional flight and hotel booking endpoints integrated into the site • Complete PayU implem...
