# Initializing a Chargebee instance

Inside your JavaScript code, initialize chargebee with the publishable key (opens new window) once the page is loaded and get 'chargebee instance' object. This object is used further to create components.

Example:

var cbInstance = Chargebee.init({
	site: "site-name", // your test site
	domain: "https://mybilling.acme.com" // this is an optional parameter.
    publishableKey: "test__"
})

# Create a Payment Intent

You should create a payment intent before submitting the form to authorize the payments.

payment_intent performs the essential function of tracking different events involved in a transaction. This includes:

  • Automatically changing its status based on the outcome of authorization and capture events.

  • Automatically refunding in case of an error post-payment.

A payment_intent can be created at your server-side using create a payment intent API (opens new window) and returned to the client side. The payment method handler uses the created payment_intent internally to perform authorization.

Here's the sample code to create a payment_intent.

TIP

This must be done from your backend to avoid exposing sensitive data.

Example:

  • Curl

The above step should be initiated as a request from your front end.

Front end code:

function createPaymentIntent() {
  return fetch('/payment-intents', {
    method: 'POST',
    body: JSON.stringify({
      amount: 500,
      currency_code: 'PLN',
      payment_method_type: 'online_banking_poland'
    })
  }).then(function(response) {
    return response.json();
  }).then(function(responseJson) {
    return responseJson.payment_intent;
  });
}
