Frequently Asked Questions

Common questions about WebToffee Universal Commerce Protocol Enabler for Woocommerce

Yes. The plugin declares full compatibility with WooCommerce High-Performance Order Storage (custom order tables).

Version 2026-08-25, published at /.well-known/ucp. Version 2026-04-08 is also supported: the profile lists it under supported_versions, pointing to /.well-known/ucp/2026-04-08, and each request is answered in the version the platform declares. Platforms using any other protocol version receive the spec's version_unsupported error.

Yes. The buyer handoff (continue_url) and Embedded Checkout resume the checkout session's own order in both the Classic and the Blocks checkout.

Yes, under WooCommerce → UCP Enabler → General → Capabilities. Disabled capabilities are removed from the profile and their endpoints are not registered. Discount and Fulfillment are extensions and have no effect unless their parent capabilities are enabled.

All of them — coupons are validated and applied by WooCommerce itself, so usage limits, minimum spend, product/category restrictions and coupons from other extensions behave exactly as on your storefront.

The agent obtains a token from the payment handler you advertise (e.g. Stripe) and submits it to POST /checkout-sessions/{id}/complete. The Stripe handler charges it directly; for other providers, hook wbte_ucp_enabler_process_payment (see Payment Processing above). With no payment handler configured, checkouts report requires_escalation and the buyer pays on your checkout page via continue_url.

Update the API Base Endpoint field under General to the public-facing URL your proxy exposes. Make sure your proxy passes the UCP-Agent, Idempotency-Key, Authorization and signature headers through unchanged, and does not re-serialize JSON responses (that would invalidate response signatures).

Checkout-session ids (chk_…) and order ids (ord_…) are unguessable 128-bit references given only to the platform that created them; requests presenting a different platform profile are refused. Shop managers, and Identity-Linking tokens for the order's own customer, can always access them. Sessions created by earlier versions of this plugin (ucp_{number} ids) keep working with the bearer token they were issued. I'm testing with curl and get `invalid_profile_url`. UCP requires a UCP-Agent: profile="https://…" header naming the calling platform's profile. For manual testing you can turn off General → Require UCP-Agent; requests without the header are then served with every capability active.
