PayBito API — Payment Gateway Integration ExampleJavaScript

            // PayBito Webhook — payment gateway integration event handler

            const express = require('express');

            const app = express.Router();

            app.post('/webhook/paybito', (req, res) => {

              const { event, payment_id, gateway, status, amount } = req.body;

              if (gateway === 'stripe' && status === 'success') {

                // Handle Stripe card payment settlement

                fulfillOrder(payment_id, amount);

              } else if (gateway === 'paypal') {

                logPayPalTransaction(payment_id);

              } else if (gateway === 'crypto') {

                confirmCryptoSettlement(payment_id);

              }

              res.status(200).json({ received: true });

            });

Developer Tools

Full Developer Stack for Gateway Integration

Beyond credential entry, PayBito provides a complete developer toolkit — API keys, webhooks, API documentation, and domain whitelisting — to build custom payment gateway integration workflows.

API Key Management

Generate named API keys with scoped permissions. Create multiple keys for different environments — test and production — and delete all with one click.

Webhook Endpoints

Register webhook URLs to receive real-time payment events — successful charges, failed transactions, refunds, and subscription lifecycle events from all three gateways.

API Documentation

Full REST API reference for creating payments, querying transaction status, managing products, and handling webhooks across your integrated payment gateway stack.

Domain Whitelisting

Restrict which domains can use your API keys. Lock down your payment gateway integration to your approved domains — preventing key abuse from external sources.

Recurring Billing API

Programmatically create and manage subscription plans across Stripe, PayPal, and crypto gateways via the API — automate billing cycles and lifecycle events.

Payment Link Generation

Create payment links, buttons, QR codes, and hyperlinks programmatically through the API for all integrated gateways — one-time and recurring both supported.
