WooCommerce plugin

Accept Blitz Commerce checkout on a WordPress/WooCommerce store with no custom code — install the plugin, enter your API key, and go.

Install

• In WordPress admin, go to Plugins → Add New → Upload Plugin and upload the zip.
• Activate it, then go to WooCommerce → Settings → Payments → Blitz Commerce and paste in an API key with the checkout:write scope (see Authentication).
• Add a webhook endpoint pointed at your store (see Webhooks), subscribed to checkout.completed — the plugin listens for it to mark orders paid automatically.

What it does

On checkout, it calls the same server-to-server Checkout API described in the Checkout docs, then redirects the buyer to Blitz's hosted Stripe/PayPal checkout page. When the checkout.completed webhook arrives, it verifies the signature and marks the matching WooCommerce order as paid — no manual reconciliation needed. Works with both the classic shortcode checkout and Cart/Checkout Blocks.
