Stripe Connect.

Integration of Stripe Connect Into Your Project

Almost every service on the Internet today deals with money. And dealing with money requires a robust Billing system. Building your own billing system is a pain. It is a crucial component that should be highly available, secure, and 100% bug-free, otherwise, your users or your business might lose some money, which is unacceptable.At Mad Devs, we prefer to use robust, suitable, and resource-saving solutions if possible. That is why we often use Stripe & Stripe Connect to enable billing for our products. That saves our clients a lot of time, money, and negative emotions.Stripe as well as Stripe Connect is very easy to integrate: it has a lot of documentation and very simple and powerful API. Yet, for those who are new to online payments & e-commerce Stripe integration might cause issues and unexpected side effects. This article is to describe some of our lessons learned so that when you integrate Stripe Connect for your business, you are easy to avoid or overcome them.If you link cards to your users' accounts, or you accept card payments make sure users authorize the cards, otherwise you might have a lot of fraud resulting in disputes. Cards authorization happens in several steps, you request basic card details and make sure they are passed to Stripe so that it can verify the card. But it is very easy to break defense if a person has stolen/scanned a card. To completely avoid cases of stolen cards being used, use the 3D Secure.

Internal and external stakeholders in IT

Internal and External Stakeholders Types, Differences, and Roles

World politics and economics have bound most countries together and made companies more dependent on each other than ever before. Resource and component suppliers, manufacturers, distributors of goods and labor, as well as sales markets, are spread across the planet. You could say that almost no full-service companies are left that don't depend on other companies.
