Quickstart Guide

This guide will help you integrate SwiftPay into your application and start accepting payments.

​
1. Get Your API Key

1

Sign Up

Create an account at app.swiftpay.cx and complete the onboarding process.
2

Get Approved

Wait for your business to be approved by our team. You’ll receive an email notification.
3

Generate API Key

Navigate to Settings → API Keys in your dashboard and create a new API key.
Keep your API key secure! Never expose it in client-side code or public repositories.

​
2. Create a Checkout Session

Create a checkout session to start accepting payments: 
curl -X POST https://api.swiftpay.cx/api/checkout/sessions \
  -H "Authorization: Bearer mp_live_your_api_key" \
  -H "Content-Type: application/json" \
  -d '{
    "items": [
      {
        "name": "Premium Plan",
        "price": 29.99,
        "quantity": 1
      }
    ],
    "customer": {
      "email": "customer@example.com"
    },
    "urls": {
      "success": "https://yoursite.com/success",
      "cancel": "https://yoursite.com/cancel"
    }
  }'

​
3. Redirect to Checkout

Redirect your customer to the checkout page: 
// Redirect to the checkout page
const checkoutUrl = `https://app.swiftpay.cx/checkout/${session.data.id}`;
window.location.href = checkoutUrl;

​
4. Handle the Result

After payment, the customer is redirected to your success or cancel URL.
For production applications, always verify the payment status via webhook or API call instead of relying solely on the redirect.
Configure webhooks to receive real-time payment notifications: 
curl -X POST https://api.swiftpay.cx/api/webhooks \
  -H "Authorization: Bearer mp_live_your_api_key" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://yoursite.com/webhooks/swiftpay",
    "events": ["checkout.succeeded", "checkout.failed", "refund.created"]
  }'
The response includes a secret that you’ll use to verify webhook signatures.
