Full-Featured Payments

USE CASES

Both of our full-featured APIs can be used to collect raw credit card information through your custom app and submit it to the payment processor. Use the returned transaction token to perform follow-up actions including recurring payments, tip adjustments, refunds, and voids.

Or to reduce your PCI responsibility, use the payment provider’s app to collect and transmit credit card information, keeping that data separate from your systems. Then use one of the full-featured APIs below to securely perform follow-up actions by passing in the returned token representing the transaction data.

Server Post API
Send payment requests from an agent- or customer-driven user interface through your servers, directly to our in-house processor EPX for real-time payment processing.

Custom Pay API
Accept payments from a backend server, POS system, website, or payments gateway and submit directly to our in-house processor EPX for real-time payment processing.

FEATURES

Flexibility
Accept online and in-person payments, and perform follow-up actions such as refunds or voids using a token, with no need for the customer to enter their card data again. Access raw transaction data for complete customization and control over your payment environment.
Functionality
Unlock advanced functionality with a comprehensive set of endpoints including ACH Sale, Incremental Authorization, Invoices, Subscriptions, EBT, Address Verification Service (AVS) Sale, and more.
