What is Payment Gateway?

Payment gateways are online payment services that, when connected to an E-commerce platform, serve as a channel for making and taking payments.

The process for receiving payments requires the client to provide certain information including credit/debit card information the expiry date, as well as CVV.

Following this, the client is able to pay and the money is transferred from the account of the buyer onto the seller’s (merchant’s) bank account.

What is Payment Gateway and is Role

The primary function of an internet-based payment processor is to authorize the process of transactions between the customers and merchants.

It plays an essential role in the process of online transactions and allows transactions between customers and merchants.

It allows the e-commerce platform to enhance its standing by providing a variety of payment options to its customers.

In addition, it leads to the e-commerce platform developing a reputation for bringing not just quick and secure transactions but also ease of use and success each time.

The payment gateway service could be offered by banks directly or a third-party payment service provider that is authorized by banks.

Difference Payment Gateway vs Payment Processor.

Once we have mastered the basics, let’s proceed to more specific. This is a quick overview of the differences between payment gateways and payment processors.

Payment processors facilitate transactions between two parties feasible.

But, a payment gateway (PG) captures the details of the payment made by the customer and sends this information back to the processor. Thereafter, the PG transmits the status of the transaction between the buyer and the seller. (the merchant)

Then, open AndroidManifest.xml and then add this singleton class into the tag by using the android: name property. It will start the class at the moment the app is launched. Make sure to add the INTERNET permission since we will be making network calls.

<uses-permission android:name="android.permission.INTERNET" />
