The CreptaPay plugin adds a Pay with stablecoins option to your WooCommerce checkout. The customer pays with USDC or USDT on the secure CreptaPay checkout page, then returns to your order confirmation page. The order is marked paid as soon as CreptaPay confirms the payment.

​
Requirements

  • WordPress 6.0 or later, with WooCommerce
  • PHP 7.4 or later
  • Your site on https, so CreptaPay can send payment updates to it
  • A store currency CreptaPay supports: USD, EUR or NGN

​
Set up

1

Install the plugin

Download the latest release .zip from GitHub.In WordPress, go to Plugins → Add New → Upload Plugin, choose the .zip, and click Install Now. Then click Activate.
2

Get your API keys

In the CreptaPay dashboard, open Developer → API keys. Copy your test public key (pk_test_…) and secret key (sk_test_…). The secret key is shown in full only once, when you generate it.
3

Add your keys to WooCommerce

Go to WooCommerce → Settings → Payments → CreptaPay.
  1. Tick Enable CreptaPay.
  2. Leave Sandbox mode ticked.
  3. Paste your test keys under Sandbox keys.
  4. Click Save changes.
Saving registers your store’s webhook with CreptaPay automatically. The table at the top of the page shows whether it worked.
4

Place a test order

Add a product to your cart and check out with Pay with stablecoins. Pay on the sandbox checkout with test funds. When the payment confirms, the order moves to Processing (or Completed for virtual and downloadable products).
5

Go live

Complete business verification (KYB) in the CreptaPay dashboard. Then paste your live keys (pk_live_…, sk_live_…), untick Sandbox mode, and save.

​
Order statuses

The plugin re-checks every payment with CreptaPay before it completes an order, including the amount and currency. Every update from CreptaPay is verified with your secret key.

Troubleshooting

Make sure your site is public and uses https. Check that no security plugin or firewall blocks POST requests to /wc-api/creptapay/. Then save the settings again to re-check.
Check that Enable CreptaPay is ticked and your keys for the current mode are saved. Your store currency must be USD, EUR or NGN (WooCommerce → Settings → General → Currency).
CreptaPay can’t reach a local site, so updates won’t arrive. Orders are still checked when the customer returns to the thank-you page. To test webhooks locally, expose your site with a tunnel such as ngrok.
In the CreptaPay dashboard, open Developer → Logs and resend the delivery for that payment. Turn on Debug log in the plugin settings to see what happened.
