Payment Integration — Fintroops Fintech Internship Experience

This blog is about the final semester internship experience at Fintroops Fintech Solutions PVT LTD. This blog will discuss the outcome of our assignments, and various other factors which contributed to both personal and professional growth.

Fintroops helps startups by providing financial advice and managing financial practices. Many startups don’t charge the users because of their inability to store the credit information securely. Fintroops now gives hope to startups for storing the user financial information and managing financial practices on their own.

Fintroops only goal is to help fintech startups from development to marketing. As there is huge growth in personal financial management applications, this trend will only benefit companies hold in the area.

Payments integration with apps deals with many gateways for processing.

According to the use case, we have two types of gateways: Static & Dynamic Gateways. Static gateways are relatively easy to develop as there is only one web link for all transactions done by the users because the price the specific and fixed to a webpage.

In constrat, dynamic gateways are complex which require seamless integration with the webpage where the user chooses their service/products accordingly. The payment information from the user is then processed through these gateways, and these transaction details are stored in our database for compliance.

Client requirements for payment integration usually impact the aspect of development. International payment gateways such as PayPal are widely used by many companies whether currency conversion and international acceptance of payments is a factor which determines which gateways to use, domestic gateways such as razor pay, etc are also gaining popularity among regional startups.

Use-case and time constraints will define which deployment is best suited. Given more time, an integration that is seamless and specific to an application can make the process less cumbersome for users and no loss in business for client-webpage.

KICKMUSIC

A webpage with music content classified among two categories: premium and free. The premium content is only available to the users who have subscribed to the paid service. At first, the user needs to register and make their accounts, the emails which are validated should be stored in the database as users with only access to free content.

The webpage will have various subscription models for the premium content and will require user selection to proceed. The amount/plan selected will be fixed which would need a static gateway to process the transaction. The user’s data are stored in the databases for a hassle-free experience for repayments, and the payment gateway will process the transaction with a unique code and necessary details which will also be stored in the database in case of an audit, query, and refunds.

The backend technologies that are being implemented here are PHP,sqlite3 DB for the backend. For Frontend development, we have CSS, HTML, and javascript being used for the webpage. Composer bridges PHP and the payment gateway.

As there are many internationally established gateways, this project will utilize Stripe, an American financial service mainly competing with Paypal as a cheaper alternative due to comparably less compression and conversion rates.

After user registration and validation, all data pertaining to the user are encrypted through SHA 256 and stored in our database due to the sensitivity of user information. After the user successfully creates an account, to use the application he has to log in with the same credentials, where email is validated through Secure-Links.

LEARNING OUTCOMES

The main learning outcome that any individual would get from an internship is personal and professional growth. This being a startup has a comparatively higher chance to interact with industry professionals and learn from the exposure gained from them. This has given me a proper intuition about both the theoretical and practical organization of team’s work to enhance software engineering best practices.
