How to Build an Agentic Commerce Protocol Integration (ChatGPT Instant Checkout)

Svix offers a webhook infrastructure for both startups and large enterprises, enabling developers to handle reliability, scale, retries, and security with a single API call. The recent introduction of the Agentic Commerce Protocol (ACP) by OpenAI allows agents like ChatGPT to facilitate direct purchases from merchants, maintaining customer relationships and leaving post-purchase processes in the hands of merchants. ACP is structured into three phases: product discovery, checkout, and payments, with Svix supporting the integration of these processes through webhooks. The product discovery phase involves merchants sharing structured product data, while the checkout flow requires multiple API endpoints and webhooks to manage the order lifecycle. The final payment phase may involve existing merchant payment methods or the Delegated Payment Spec, primarily implemented by payment providers like Stripe. Although currently supported only by ChatGPT, it is anticipated that other agent companies will adopt ACP, and Svix is committed to aiding this transition with tools and resources, such as the newly released Svix ACP connector and helper libraries available in various programming languages.
