Integrating payments into your website - four ways, without building a checkout from scratch
Most businesses do not need to build a payment system. They need the customer to pay on the site, the money to arrive, and the invoice to go out by itself. There are four ways to connect that, from the simplest one that works today to a full integration from your own code.
How to integrate a payment system into a website
Integrating payment systems into a website, also called implementing or connecting a payment system to a site, connects the "pay" button on your site to the processing that moves the money. There are four ways to do it: a payment link the site points to, a sale page embedded inside the site, an API your code calls to create a payment request, and importing orders from an existing store for invoicing. In every case the customer pays on a secure page, by credit card, Bit, Apple Pay or Google Pay, and the invoice can be issued automatically the moment the payment succeeds. The right way depends on one question: how much control you need over the checkout experience, and how much development you are willing to do for it.
What the integration includes
1. Payment link - no code
Create a payment request, get a link and a QR code, and put it on a button on your site, in WhatsApp or in an email. The customer pays on a secure payment page and you see the status in the system. It is the fastest way, and it suits most businesses.
2. A sale page embedded in your site
A sale page with products and a cart that you can place inside your site with ready-made embed code (iframe) or share as a link. Only a published page is shown, and payment goes through the same secure checkout.
3. API and webhooks for developers
Your code creates a payment request and gets a real payment link back, reads the transaction list, and opens a refund request that is approved in the system. Events such as a request being created and a payment being completed are sent to your server by webhook, so the site knows when to release an order. Access is by API key with separate read and write scopes.
4. Orders from an existing store
Already have a WooCommerce, Shopify or Wix store? Orders are imported into the system and produce an invoice, without retyping them. It connects orders to invoices; it does not replace the store's checkout.
Bit, Apple Pay, Google Pay and PayPal
The payment page offers the methods customers in Israel actually use today, not only a credit card. PayPal and bank direct debit (Masav) are available when they are enabled on the business's merchant account.
3DS and instalments
The 3DS authentication policy is your setting, not a blanket rule. Instalments can be allowed, and chargebacks appear on a dedicated screen with status and alerts.
The invoice goes out by itself
When a card or digital-wallet payment succeeds, the system issues an invoice and returns the invoice number and a PDF link. You can turn this off for a specific payment request or for the whole business. If invoice generation fails, the payment itself is not affected and the failure is logged.
A returning customer does not re-enter a card
Saved payment methods, recurring subscriptions and a customer portal where the customer updates a card, sees invoices and pauses or cancels a subscription. Card details are stored as an encrypted token, not as a visible number.
