How to add retail media to a ChatGPT app
Add retail media to a retailer's ChatGPT app by connecting the app to a product search that returns labelled sponsored products, such as the ATS MCP server, and following OpenAI's app guidelines on disclosure.
Build the app
OpenAI's Apps SDK builds ChatGPT apps on MCP. Connect the ATS MCP server for product search.
Show sponsored products
Return relevant sponsored products with the organic ones and label them on each card.
Hand off checkout
Send the shopper to the retailer's own basket; PA does not run checkout.
Same for Claude
Claude connectors work the same way; see retail MCP product search.
Run it with Particular Audience
Sponsored Prompts runs on Adaptive Transformer Search and the open-source ATS MCP server. Advertisers pick products or a collection; each item surfaces automatically, labelled, in chats, prompts and AI searches where it scores highly.
