A payment gateway is a service of performing electronic transactions to receive or transfer money from the end customer’s account to the merchant. It is used for payment authorization. Payment gateway integration in the mobile application (iOS or Android) ensures that businesses can accept payment more simply and quickly. It serves as an intermediary portal that facilitates successful transaction flow by making use of security protocols and industry-standard encryption to manage and transfer transaction data safely.

Step 1:
Customer places the order by submitting preference and clicking the “Buy now” button or equivalent options.

Step 2:
The online store redirects the consumer to a payment gateway to enter all the relevant credentials about the bank or the card.

Step 3:
The gateway helps;

• Forward the transaction data to the acquiring bank (the acquirer or merchant bank ~ institution dealing in commercial loans and investment.)
• Identifies credit card provider (MasterCard, Discover, Visa, or American Express)
• Routes the transaction information to the right payment switch

Step 4.1:
The issuer bank (a financial firm that provides credit and debit cards to customers) applies fraud detection procedures to check the authenticity of the transaction. It confirms whether the buyer has enough credit in their account to facilitate the procurement.

Step 4.2:
The issuer bank either accepts or rejects the payment request and transfers this information back via the credit card network to the payment gateway and the merchant bank. The response code helps to communicate the cause of a failed transaction, for instance, insufficient funds, and others.

The customer gets a confirmation as a message via a payment system interface of the order being placed, once the above process is complete before they even realize – within a fraction of few seconds. How about that?

Let’s look at some reasons why and how utilizing integrated payments can provide an edge to your business and offer a competitive edge.

Here’s a step-by-step guide that you might find useful if you don’t know where to begin or how long would it take to make your payment integration work.

Step 1:
Decide on the type of Payment Getaway and plan the integration process: Based on the size of business, industry & country targeted to determine which payment gateway would best suit the needs.

Step 2:
Add Client Tokens: It is necessary to obtain a client token when the server sends a request from your app. It is a good practice to generate a new token on every app launch. It consists of all the authorization and configuration specifics to allow the client to initialize the SDK. This is achieved by using numerous programming languages and frameworks, including JavaScript, React, Java, .NET, PHP, Python, and Ruby on Rails

Step 3:
Testing: Here, software testers verify the working of the payment gateway integration with credentials such as merchant ID, public and private keys.

Step 4:
Security certifications: To increase the level of security it is important to consider installing additional certifications that comply with the PCI-DSS. Further, the Secure Sockets Layer (SSL) guarantees protection for the clients’ and merchant’s sensitive information.

Step 5:
Payment Processing: When processing a transaction, the one-time payment method needs to be configured on the server. It works as follows: the client sends you card information, the gateways forward it to the server, and it uses the data to initiate the transaction.
