Frequently Asked Questions

Can Basys customize an API that works with applications we have written?

Yes. Using our Connect Web Service, your developers can directly integrate payment processing into your custom applications for order entry, invoicing, and more.

This API-driven approach is more flexible than file transfer protocols or Connect interfaces, and allows your team to:

Process Sales, Credits, Authorizations, and Voids
Query existing transactions for status and confirmation
Communicate directly with the merchant’s Gateway account

We’ll provide full API documentation and hands-on support to ensure a smooth, successful integration.
