crypto payment gateway
API, plugins & integrations.

The WooCommerce crypto payment gateway plugin for WordPress: drop a single PHP file into your plugins folder, paste your sk_live_* and whsec_*, and 'pay with crypto' appears at checkout. Auto-confirms orders on payment.confirmed, marks them on-hold on under/overpaid.

1. Download → wp-content/plugins/cryptpe/cryptpe-payment-gateway.php
2. WP Admin → Plugins → Activate "CRYPT.PE Crypto Payments"
3. WooCommerce → Settings → Payments → enable "Pay with CRYPT.PE"
4. Paste your sk_live_* + whsec_* from the CRYPT.PE dashboard

Zero dependencies. Native fetch on Node 18+, https fallback on 16. Includes a webhook signature verifier with constant-time HMAC comparison.

curl https://crypt.pe/api/sdk/node -o cryptpe.js
# then in your app:
const Cryptpe = require('./cryptpe');
const cryptpe = new Cryptpe(process.env.CRYPTPE_SECRET_KEY);
const order = await cryptpe.payments.create({
  amount_usd: 49, accepted_coins: ['eth','matic','usdc-erc20'],
});
res.redirect(order.checkout_url);

Anything that can speak JSON can integrate. Stripe-style endpoints, idempotency keys, Bearer auth. See the full reference in our docs.

curl -X POST https://crypt.pe/api/v1/payments \
  -H "Authorization: Bearer sk_live_..." \
  -H "Content-Type: application/json" \
  -d '{"amount_usd": 49, "accepted_coins": ["eth","matic"]}'

Accept crypto payments on Shopify today via our drop-in JS button + a custom Liquid checkout snippet — the customer pays the cart total on a hosted crypto checkout and a webhook flips the order to paid. Native one-click Shopify App is in review with the App Store — shipping Q2 2026.

1. Dashboard → Gateway card → create an sk_live_* key + save the whsec_*
2. Shopify Admin → Online Store → Themes → Edit code → add the liquid snippet to your cart/checkout template
3. Paste your publishable settings into the snippet — the button sends the cart total to a hosted crypto checkout
4. Point the webhook at your order-flip endpoint (full walkthrough in the guide) → orders auto-mark paid

Drop-in cryptpe Python module — same surface as the Node SDK, stdlib only (nothing to pip install). Webhook verification + payments client built in.

curl https://crypt.pe/api/sdk/python -o cryptpe.py
# then in your app:
from cryptpe import Cryptpe
cryptpe = Cryptpe(os.environ["CRYPTPE_SECRET_KEY"])
order = cryptpe.payments.create(
    amount_usd=49, accepted_coins=["eth", "matic"])
redirect(order["checkout_url"])

Same architecture as the WooCommerce plugin — drop the module into app/code/Cryptpe/Payments, run setup:upgrade, and pick CRYPT.PE in Store → Configuration → Sales → Payment Methods.

1. Download → unpack into app/code/Cryptpe/Payments/
2. bin/magento setup:upgrade && bin/magento cache:flush
3. Store → Configuration → Sales → Payment Methods → enable "CRYPT.PE Crypto Payments"
4. Paste your sk_live_* + whsec_* → set the webhook URL shown on the config screen
