When building new products, onboarding is always expensive, cumbersome, and slow. It takes months to create accounts, payment credit cards, and manage budgets, even if complete documentation is provided. How are you supposed to keep up with the competition? How much time and money do you waste on developing? Well, enough to put growth on hold.

Fortunately, the latest digital solutions continue to transform the financial ecosystem. One of these innovations is embedded finance which enables developers to create custom workflows and internal power tools like virtual card issuance — all with a single integration. This gives your customers increasing control over their funds and simultaneously grows your business with new revenue streams.

What is a credit card API?

APIs, or Application Programming Interfaces, are the digital backbones of many popular online services. They are a direct link between two software applications, allowing them to interact. API-driven products allow developers to create and deploy new services without interacting directly with a financial institution’s back-end systems. Virtual card issuing, payments, budgets, and more features can be integrated and automated by an API with less time and money.

How APIs can streamline business and developer workflow

Ready-to-use financial stack. You can easily create a financial account and optimize spend management with automated payments and other transactions. Also, API can act as a virtual card issuer and give your customers more flexibility in day-to-day spending.

Better user experience. API makes it easy for your customers to pay bills, manage cash flow and hold funds. Every credit card API can be tailored to your user's needs, preferences, and budget.

Less time and hassle on developing. The payments API automates the basic tasks. Developers can call an API whenever they want to input data to a server without breaking a sweat.

Thousands of dollars saved. There's no need to build a complicated system with huge resources. You can shift saved funds to grow your business.

Real-time data access. Automatic payments are recorded in your company's transaction history, reducing the chance of errors during manual processes.
