KH Payment

GET STARTED WITH KH PAYMENT

Your first payment.
See how it comes together.

From a few lines of code to a customer checkout. Take a quick tour, then build it your way.

The plugin, skill and MCP are in the private source checkout. Follow the setup guide for Codex or Claude Code. A public skill installer and marketplace listing remain planned.

  1. Call the endpoint

    Your server calls the payment API with an amount, currency and unique idempotency key. Open the returned checkout URL in a popup, or use the full-page fallback.

  2. Scan the QR

    The checkout displays the SHOP payment card. Open your banking app and scan the QR code.

  3. Pay and continue

    Review the amount and tap Pay. Once the provider confirms the payment, the checkout shows the completed result and a Continue control. Your server verifies the payment status before confirming the order; scanning alone never marks a payment paid.

  1. Install the plugin

    Build the private source checkout, register its marketplace in Codex or Claude Code, then install KH Payment from the host’s plugin browser. Configure a test key privately and restart the host session.

  2. Ask for the integration

    Tell your agent: “Implement this QR code payment for me. Create the checkout and polling.” The skill guides the agent through server code, order ownership, checkout and rate-limit handling.

  3. Review and integrate

    Review and test the generated server code. Keep the API key private, poll sequentially every three seconds, honor Retry-After and stop when complete. MCP payment creation still requires human confirmation. Signed outbound webhooks are the next backend milestone.
