TRXPS offers easy to use and easy to integrate server-side APIs to process payments with a customizable payment page that lets you collect payments quickly.
You can see a demo here.
You can use this API to initate a 'Checkout' and redirect your customer to the given payment page. After the payment was successful TRXPS will redirect your customer back to you.
Additionally, we will notify you if someone has successfully paid the initiated checkout.
All endpoints are only available via HTTPS.
