Authorize.net is a United States-based payment gateway service provider, allowing merchants to accept credit card and electronic check payments through their website. Now a subsidiary of Visa, the platform handles the full transaction lifecycle — from authorization and fraud detection to settlement — with built-in PCI DSS compliance, recurring billing, and support for all major card networks.

For organizations running commerce-enabled sites on dotCMS, Authorize.net can process transactions on checkout pages, gated content purchases, or subscription flows. Its API-based architecture makes it straightforward to integrate with headless front-ends powered by dotCMS content, giving development teams a reliable, well-documented payment layer without building custom processing infrastructure.
