Four checkouts on a live WooCommerce store.
These four rows are from a live WooCommerce checkout. The same column names Claude, Perplexity, Google Agent, Meta, Amazonbot, Mistral, and the other published agents when they are the ones who checked out. A name in the user-agent is not proof. If the signature fails, the order stays Unknown.
What you get
- A Buyer column on the orders list, and a box on the order.
- Signed when the agent’s key checks out on your server.
- Declared when the user-agent is a published agent and nothing was signed.
- A Monday email only when an order was not a person.
Checkout is never blocked. Copilot and Grok usually look like a normal browser, so they stay Human until they sign.
Questions store owners ask
-
How do I know if ChatGPT, Claude, or a person placed this WooCommerce order?
Open the order. It says Human, a named agent, or Unknown.
-
The user-agent says ChatGPT. Is that proof?
No. A name in the user-agent is declared. Proof is a signature that matches the published key. If it fails, the order stays Unknown.
-
Should I block AI agents from my WooCommerce store?
No. Label the order first. Checkout is never blocked.
-
GPTBot visited my site. Did someone buy?
No. GPTBot is a crawler. A shopper shows up as ChatGPT-User.
-
Why do AI orders show up as Direct in WooCommerce?
The referrer was stripped. The stamp reads the checkout request, not the traffic report.
-
What does Unknown mean on a WooCommerce order?
The plugin will not name the buyer. It is not a fraud verdict.
-
Is Google Agent checking out on my WooCommerce store?
Look at the order. Google-Agent with no signature is declared. A matching signature from agent.bot.goog is signed. Googlebot is the crawler, not the checkout.
-
Perplexity or Claude bought something. Where do I see it?
On the order. Perplexity-User is stamped Perplexity. Claude-User is stamped Claude.
-
How do I add Agent Stamp to my WooCommerce store?
You get a zip. Upload it under Plugins, Add New, then place one order.
See it on your store
Send the store URL. We put Agent Stamp on that WooCommerce shop and walk through one order. You get the plugin after that. No mail app, no account.
