As of now, ChatGPT Instant Checkout is available only for merchants operating in the United States.
If your online store runs on Shopify or Etsy, you can already take advantage of this feature without any additional implementation, since these platforms are directly supported by OpenAI’s infrastructure.

For custom-built or enterprise e-commerce systems, a dedicated integration following the Agentic Commerce Protocol (ACP) is required.
Rankwit can assist your team in developing this integration—allowing you to access the U.S. market immediately and prepare for future international expansion as OpenAI rolls out the program globally.
