To add a gateway payment method in node express js, you need to follow the following steps:
Install a payment gateway library for Node.js, such as Stripe or Paypal.
In your Express application, import the payment gateway library and configure it using your API keys.
Add a route in your Express application to handle payment submissions. This route should receive the payment information from the client, such as the amount and credit card details, and pass it to the payment gateway library for processing.
Choose a Payment Gateway: First, you need to choose a payment gateway that you want to integrate with your node express js application. There are many payment gateways available in the market such as PayPal, Stripe, Braintree, etc.
Create an Account: Once you have chosen the payment gateway, you need to create an account on their website. You will be provided with a set of keys and credentials that you will need to integrate the payment gateway with your application.
Install the Payment Gateway Package: To integrate the payment gateway with your node express js application, you need to install the payment gateway package in your application. For example, if you choose Stripe as your payment gateway, you need to install the “stripe” package in your application. You can install it by running the following command in your terminal:-
npm install stripe
Initialize the Payment Gateway: After installing the payment gateway package, you need to initialize it in your application. You can do this by requiring the payment gateway package and setting the API key in your application. Here is an example of how you can initialize the Stripe payment gateway in your application:
var stripe = require(“stripe”) (“your-stripe-api-key”);
Add Payment Route: Next, you need to add a payment route in your node express js application that will handle the payment processing. This route will be responsible for creating a payment session, creating a payment token, and charging the customer. Here is an example of how you can create a payment route in your application:
app.post(“/charge”, async (req, res)=> {try {
let {status} =await stripe.charges.create({
amount: 2000,
currency: “usd”,
description: “An example charge”,
source: req.body.stripeToken
});
res.json({status});
} catch (err) {
res.status(500).end();
}
});
Add a Payment Form: Finally, you need to add a payment form in your node express js application that will allow customers to enter their payment information. You can create a form that contains the fields for entering the card details and a submit button. You can also use the payment gateway’s API to create a secure payment form that will securely handle the payment information.
Test the Payment Gateway: Once you have completed the above steps, you need to test the payment gateway to make sure that it is working as expected. You can test it by making a test payment and checking if the payment was processed successfully.
This is a general overview of how you can add a gateway payment method in node express js. You can find more detailed information and examples on the payment gateway’s website.
