Accept payments through Paddle on your Komerza store. Paddle handles the checkout UI - your customers are redirected to a secure Paddle-hosted payment page, then returned to your store once payment is complete.

​
Prerequisites

1

Get Your Paddle API Key

  1. Log into your Paddle Dashboard
  2. Go to Developer Tools → Authentication
  3. Click Generate API Key
  4. Copy the key - it starts with pdl_live_
Testing first? Use the Sandbox Dashboard instead. Sandbox keys start with pdl_test_ and no real money is charged.
2

Connect Paddle to Komerza

  1. In your Komerza dashboard, go to Payment Methods
  2. Find Paddle and click Configure
  3. Paste in your API Key (from Step 1)
  4. Click Save
Komerza automatically creates the webhook endpoint on your Paddle account. No manual webhook configuration needed.
3

Verify the Connection

Go to Payment Methods → Paddle in your dashboard. The status will show:
  • Active - Everything is connected and working
  • Inactive - Check that your API key is correct
If the status shows Inactive, double-check that your API key starts with pdl_live_ (or pdl_test_ for sandbox).

​
How It Works

  1. A customer selects Paddle at checkout
  2. They’re redirected to Paddle’s secure hosted checkout page
  3. After paying, they’re sent back to your store with a confirmation
  4. Komerza receives a webhook from Paddle confirming the payment and delivers the order automatically

​
Managing Payments

  • Refunds - You can issue full refunds through Komerza. The refund is processed via Paddle’s system and the customer is credited back.
  • Disputes - If a customer opens a dispute with their bank, you’ll receive a notification in Komerza. The order is marked as disputed and you can respond through Paddle’s dashboard.

​
Sandbox Testing

If you want to test before going live:
  1. Create a Sandbox account
  2. Use your sandbox API key (pdl_test_...)
  3. No real charges are made - you can test the full flow safely
  4. When ready, disconnect and reconnect with your production API key

​
Disconnecting Paddle

Go to Payment Methods → Paddle and click Disconnect. This also removes the webhook endpoint from your Paddle account. Your existing orders are not affected - only new checkouts will no longer offer Paddle.
