I need a smooth, secure PayPal payment gateway added to my website so customers can complete one-time purchases using either their credit/debit cards or their PayPal balance. Subscriptions or donation flows are not required—just straightforward checkout for product sales. The job covers: • Connecting the site to PayPal’s REST API (or the latest recommended SDK) • Displaying PayPal-hosted buttons or custom-styled buttons that support the two payment methods mentioned above • Handling success, cancellation, and error callbacks and writing clear server-side logic to confirm transactions • Returning a clean confirmation page to the buyer and sending any necessary webhooks or order data back to my system for record-keeping • End-to-end testing in PayPal sandbox followed by a live switch-over once everything passes Acceptance criteria: the gateway must process real card and PayPal balance payments without errors, reflect correct totals, and log each transaction in a simple report I can review. Please tell me which language or framework you plan to use, how long the integration should take, and any past PayPal projects you can point me to.

I can integrate the PayPal payment gateway using the latest PayPal REST API or SDK based on your site’s backend language (please confirm which language/framework your website uses). The integration will include both PayPal balance and card payments with secure server-side transaction confirmation and handling of success, cancel, and error callbacks. I’ll add either PayPal-hosted buttons or fully custom-styled buttons as you prefer and ensure a simple order logging system that outputs a clear report you can access. Testing will be done thoroughly in the PayPal sandbox before switching to live. Typically, this takes 1-2 days depending on your current setup and tech stack. I’ve integrated PayPal payments in multiple projects—handling one-time product sales with clean confirmation flows and webhook recording. Could you share which backend language/framework your site is built on (e.g., PHP, Node.js, Python)? Also, do you prefer default PayPal smart buttons or fully custom buttons styled for your UI?
