# Stripe Payment Gateway Integration

Integrating the Stripe payment gateway into your application can streamline your payment processing and enhance user experience. Here’s a step-by-step guide.

## Prerequisites
- **Stripe Account**: Create an account on the [Stripe website](https://stripe.com).
- **API Keys**: Obtain your API keys from the Stripe dashboard.

## Installation
To get started, you need to install the Stripe SDK. You can do this using npm:

```bash
npm install stripe
```

## Basic Setup
Here is a basic setup for initiating the Stripe client:

```javascript
const stripe = require('stripe')('your-secret-key');
```

## Creating a Payment Intent
To process a payment, you need to create a Payment Intent:

```javascript
const paymentIntent = await stripe.paymentIntents.create({
  amount: 1000, // amount in cents
  currency: 'usd',
  payment_method_types: ['card'],
});
```

## Handling Webhooks
To receive notifications about payment status, set up a webhook endpoint:

```javascript
const express = require('express');
const app = express();
app.post('/webhook', express.json(), (req, res) => {
  const event = req.body;
  // Handle the event
  res.json({ received: true });
});
```

## Testing Payments
Use the test cards provided by Stripe to test your integration:
- **Visa**: 4242 4242 4242 4242
- **MasterCard**: 5555 5555 5555 4444

## Conclusion
Integrating Stripe can greatly enhance the payment processing capabilities of your application. Be sure to check the [Stripe documentation](https://stripe.com/docs) for more detailed instructions.
