Accept One-Time Crypto Payments

One-time payments let customers pay using crypto, similar to a standard checkout experience.

How it Works:

1. Create a Checkout Session using the API.

2. Redirect the customer to the hosted checkout page (url from API response).

3. Copperx handles on-chain payment tracking.

4. Copperx redirects the customer to successUrl or cancelUrl based on payment completion.

5. Optionally, receive payment status updates through webhooks.

Example API Call:

curl --request POST \
  --url https://api.copperx.dev/api/v1/checkout/sessions \
  --header 'Authorization: Bearer {API_KEY}' \
  --header 'Content-Type: application/json' \
  --data-raw '{
    "successUrl": "https://example.com/success",
    "cancelUrl": "https://example.com/cancel",
    "lineItems": {
      "data": [
        {
          "priceData": {
            "currency": "usdc",
            "unitAmount": "100000000",
            "productData": {
              "name": "Pro Plan",
              "description": "One-time access"
            }
          }
        }
      ]
    }
  }'

Best Practices:

• Validate the session’s status using API or webhooks.

• Use test mode and Copperx’s faucet for testing.
