Quick Start Guide

First, you need a ClapPay account. This is where you'll manage payments, see reports, and get your API keys.

1. Go to clappay.com/signup
2. Enter your email and create a password
3. Verify your email address (check your inbox)
4. Fill in your business details

Don't worry about having all your business documents ready. You can start testing right away and add documents later when you want to accept real payments.

API keys let your website or app talk to ClapPay. Think of them like passwords that prove who you are.

You'll have two types of keys:

• Publishable key (starts with pk_) - Safe to use in your website's JavaScript code. Anyone can see this key.
• Secret key (starts with sk_) - Keep this private! Only use it on your server. Never put it in JavaScript that runs in a browser.

An SDK is a set of tools that make it easier to use ClapPay. Pick the one that matches the programming language you're using:

Here's the basic flow to accept a payment:

1. Your server creates a PaymentIntent - This tells ClapPay how much money you want to collect and what currency to use.
2. Your website shows the payment form - We give you a ready-made form that securely collects card details.
3. Customer enters their card - The card details go straight to ClapPay. You never touch the actual card numbers.
4. Confirm the payment - ClapPay charges the card and tells you if it worked.

const clappay = require('@clappay/sdk')('sk_test_...');

const payment = await clappay.paymentIntents.create({
  amount: 2000,  // Amount in cents ($20.00)
  currency: 'usd',
  payment_method_types: ['card'],
});

// Send payment.client_secret to your frontend

Before you accept real payments, test everything with our test card numbers:
