Add Quickei as a payment method in your WooCommerce store. Customers pay by scanning a QR code or via the hosted payment page — orders update automatically.

​
Requirements

You need a Quickei merchant account with API keys. Register here if you don’t have one.

​
Installation

1

Download the plugin

Download the Quickei WooCommerce plugin from your Merchant Dashboard or from the integration page.
2

Install in WordPress

Go to Plugins > Add New > Upload Plugin in your WordPress admin. Upload the quickei-gateway.zip file and activate it.
3

Configure API keys

Navigate to WooCommerce > Settings > Payments > Quickei and enter your credentials:
  • Client ID — Your merchant API client ID
  • Client Secret — Your merchant API secret
  • Environment — Sandbox for testing, Production for live payments
4

Test a payment

Place a test order using the Sandbox environment to verify everything works before going live.

​
How It Works

​
Checkout Experience

When a customer selects Quickei at checkout:
  1. A QR code is displayed on the order confirmation page
  2. The customer scans it with the Quickei app or clicks to open the payment page
  3. Payment is confirmed in real-time — the page updates automatically
  4. The WooCommerce order moves from Pending to Processing

​
Webhook Configuration

The plugin automatically registers a webhook endpoint:
All webhook payloads are verified using HMAC-SHA256 signatures with your client_secret.

​
Event Mapping

​
Plugin Settings

Always test in Sandbox mode first. Switch to Production only after verifying that orders, webhooks, and refunds work correctly.

​
Troubleshooting

Ensure your API keys are correct and the plugin is enabled. Check your WordPress error log at wp-content/debug.log for API response errors.
Verify the webhook URL https://your-store.com/?wc-api=quickei_webhook is publicly accessible. Check that your server allows incoming POST requests from Quickei IPs.
Quickei requires HTTPS for all API communications. Ensure your WordPress site has a valid SSL certificate and WP_HOME / WP_SITEURL use https://.
