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 put their US and Canadian merchants on Authorize.net while merchants elsewhere use processors with stronger local acquiring. Voice Checkout sessions that collect card details over the phone are processed through Authorize.net’s gateway without the card details reaching the agent, and Shuttle’s Links Checkout can be configured to run 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 adding other processors alongside it, for example keeping ACH on Authorize.net while cards go through another gateway, or putting merchants in new markets on a provider that serves those markets. Shuttle also abstracts the differences between Authorize.net’s API and those of other gateways, so platforms get transaction and refund data in one format regardless of which processor handled the original transaction.
