WPMR Agentic Checkout for WooCommerce

Description

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:

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

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

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

About the Agentic Commerce Protocol

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.
– During checkout processing, payment-related request data is sent to Stripe to create/confirm payment intents and complete payment flows.
