Authorize.net + Shuttle

Authorize.net is one of the longest-running payment gateways in North America, processing transactions for hundreds of thousands of merchants across the United States and Canada. Owned by Visa, Authorize.net offers a reliable, well-documented gateway with a broad feature set that includes credit and debit card processing, eCheck/ACH payments, and automated recurring billing. Its Advanced Fraud Detection Suite provides configurable filters that let merchants set velocity limits, block specific countries, and flag suspicious transactions before they settle. For many US-based businesses, Authorize.net is the established, trusted choice for payment processing.

Shuttle’s integration with Authorize.net allows platforms to include this widely-adopted gateway as part of a broader payment strategy without building a direct API connection. Through Shuttle, platforms can route US and Canadian transactions to Authorize.net while directing international payments to processors with stronger local acquiring in those regions. Voice Checkout sessions that collect card details over the phone are processed through Authorize.net’s gateway with full PCI DSS compliance, and Shuttle’s Payment Links can be configured to settle through Authorize.net for merchants who prefer to keep their existing merchant account relationships intact.

Accessing Authorize.net through Shuttle is particularly valuable for platforms migrating from a single-PSP setup to a multi-processor architecture. Many platforms start with Authorize.net as their sole gateway, and Shuttle enables them to keep that connection active while layering in additional processors for redundancy, international expansion, or better pricing on specific card types. Shuttle also abstracts the differences between Authorize.net’s API and those of other gateways, so platforms get a consistent data model for reporting, reconciliation, and refund management regardless of which processor handled the original transaction.
