Square Card Gateway Integration
Budget: $30 – $250 USD
I need a developer who can wire up Square’s credit- and debit-card processing to both my website and its companion mobile app. The job is straightforward: when a user taps “Pay”, the transaction should be routed through Square, tokenised, authorised and logged in my Square dashboard with full PCI compliance.
The work includes
• adding the Square Web Payments SDK to the site,
• using the Square In-App Payments SDK (or equivalent) for iOS and Android,
• creating the necessary server-side endpoints to handle nonce exchange and order capture,
• returning clear success or error messages to the front-end, and
• testing everything end-to-end in Sandbox first, then moving to Production.
Acceptance will be based on:
– a live checkout flow on web, iOS and Android that charges a real card for a small amount,
– confirmation that the payment appears instantly in my Square dashboard, and
– clean, well-commented code handed over in a Git repo.
I’m looking to have this running as soon as humanly possible, so please only bid if you can jump in right away.
