Quickstart

This guide walks you through creating your first crypto payment via Hosted Checkout.

1. Get a test API key

In the ParaSta Dashboard → Developers → API Keys, copy your Secret test key (starts with sk_test_).

2. Create a Checkout Session

cURL

curl https://api.parasta.io/v1/checkout/sessions \
  -H "Authorization: Bearer sk_test_..." \
  -H "Content-Type: application/json" \
  -d '{
    "line_items": [{ "name": "T-shirt", "amount": 10000000, "currency": "USDT" }],
    "success_url": "https://your-site.com/success",
    "cancel_url": "https://your-site.com/cancel"
  }'

Node.js

const session = await parasta.checkout.sessions.create({
  line_items: [{ name: 'T-shirt', amount: 10_000_000, currency: 'USDT' }],
  success_url: 'https://your-site.com/success',
  cancel_url: 'https://your-site.com/cancel',
});

Python

session = parasta.checkout.Session.create(
  line_items=[{'name': 'T-shirt', 'amount': 10_000_000, 'currency': 'USDT'}],
  success_url='https://your-site.com/success',
  cancel_url='https://your-site.com/cancel',
)

The response contains a url. Redirect your customer to this URL to complete the payment.

3. Listen for the checkout.session.completed webhook

When payment confirms on-chain, ParaSta sends a webhook. See Webhooks → Overview for details.
