WPMR Agentic Checkout for WooCommerce enables any WooCommerce store to participate in “Buy it in ChatGPT”, OpenAI’s revolutionary feature that lets over 700 million weekly ChatGPT users discover and purchase products directly within their conversations.

This plugin implements the Agentic Commerce Protocol (ACP), the open standard co-developed by OpenAI and Stripe that powers AI-driven commerce.

Developed by WP Marketing Robot to help WooCommerce store owners tap into the future of AI-powered commerce.

How It Works

Agentic Checkout for WooCommerce works together with WP Product Feed Manager for WooCommerce, the Multi Channel product feed manager for WooCommerce:

WP Product Feed Manager generates a ChatGPT-optimized product feed for OpenAI to index
WPMR Agentic Checkout handles all checkout communication between ChatGPT and your store

When a ChatGPT user decides to buy one of your products:

Discovery: Your products are indexed from your WooCommerce site (via WP Product Feed Manager)
Buy Click: User clicks “Buy” in ChatGPT (your site must be approved/enabled by OpenAI)
Instant Checkout: Payment is confirmed in ChatGPT via Stripe (PCI-compliant)
Order Handoff: ChatGPT sends the order via Agentic Commerce Protocol
Plugin Validation: This plugin receives the order, validates inventory and shipping address
Accept/Decline: Plugin confirms or rejects the order to ChatGPT in real-time
Order Creation: If accepted, the order is created in WooCommerce as paid (status: Processing)
Fulfillment: You ship the product and provide customer support as normal

External Services

This plugin relies on third-party services to provide ACP checkout, payment processing, security validation, and connection testing.

OpenAI

OpenAI is used to support “Buy it in ChatGPT” / Agentic Commerce Protocol functionality.

Data sent and when:
– During admin connection tests, the plugin sends your configured OpenAI API key (as an Authorization header) to OpenAI’s models endpoint to verify API access.
– During IP allowlisting updates, the plugin fetches OpenAI’s published CIDR list from https://openai.com/chatgpt-connectors.json to validate incoming ACP requests.
– During normal operation, order and fulfillment webhook payloads required by ACP are sent to OpenAI when ChatGPT-originated orders are created or updated.

Stripe

Stripe is used to process payments for ChatGPT checkout orders.

Data sent and when:
– During admin connection tests, the plugin sends your Stripe secret key (as a Basic Authorization header) to Stripe’s account endpoint to verify account/API connectivity.
