How Bayon Pay works
From bank link to settled payment in six steps.
Your merchant keeps their existing bank relationship. Bayon Pay provides the integration layer your website needs.
01
Connect the bank link
Paste the merchant payment link issued by a supported Cambodian bank — e.g. an ABA Merchant Link. Never share a bank password, Merchant ID, or bank API secret.
02
Get a Bayon Pay key
Generate a scoped Bayon Pay API key for your server. The full secret is shown once and only its hash is stored.
03
Hosted checkout with KHQR/Alipay+
Create a hosted checkout session from your store and present it to the customer — KHQR or Alipay+, their choice.
04
Customer pays, bank handles it
The customer scans and pays from their own banking app. Their bank settles the funds directly to your connected account — you get paid.
05
We hook
Bayon Pay detects the confirmed payment and delivers a signed webhook event to your server the moment it settles.
06
Done
Your order flips to paid automatically — no manual reconciliation, no bank statement checking.
AI-native integration
Skip the docs. Copy a prompt.
Bayon Pay writes prompts your AI coding assistant can act on directly — real endpoints, real fields, no guessing. Paste it into Claude Code, Cursor, ChatGPT, or Windsurf and let it wire up checkout, webhooks, and status handling correctly the first time.
- Grounded in the actual API — not a hallucinated integration
- One prompt for a custom site, another for WooCommerce
- Works with any AI assistant that can read a prompt

Prompt
I want to integrate Bayon Pay (KHQR + Alipay+ payments for Cambodia) into my website. Docs: https://bayonpay.io/docs
1. Store my API key as an environment variable named BAYON_PAY_API_KEY. I'll paste the real bpk_live_… key myself — never hardcode it or put it in client-side code.
2. On the server only, create a payment with:
POST https://bayonpay.io/v1/payments
Headers: Authorization: Bearer $BAYON_PAY_API_KEY, Idempotency-Key: <unique per order attempt>
Body: { "amount": "25.00", "currency": "USD", "reference_id": "<my order id>", "metadata": {}, "prefer_alipay_plus": true }
3. Redirect the customer to the "checkout_url" from the response — don't build a custom QR renderer, Bayon Pay hosts the checkout page.
4. Add a webhook endpoint that verifies the HMAC signature Bayon Pay sends, processes each event idempotently, and marks the order paid only when the event says so — never on redirect or screenshot alone.
My stack is: [tell it your framework/language]. Write the integration for that. Written to be accurate — your assistant fetches real docs and endpoints, not guesses.

Platform core
Signed webhooks
Keep merchant order status synchronized without exposing API secrets.
Designed around trust
Your bank credential stays yours.
Bayon Pay asks for the merchant-facing payment link—not a bank login, bank Merchant ID, or private bank API credential.
Secure merchant sessions
Passwords use salted scrypt hashing and sessions use HttpOnly secure cookies.
Hashed API secrets
A generated Bayon Pay API key is displayed once; the platform stores its one-way hash.
Verified live activation
A payment rail stays disabled until the merchant’s connection and webhook setup are verified.
