What is an API?

API stands for Application Programming Interface. An API is basically a set of rules that allows two different systems to exchange data and functionality with each other. Think of it as a kind of “door” your POS system has opened so other programs and systems can use parts of it.

In restaurants and cafés, APIs are often used to connect the central POS system with other important systems, such as an online booking system, accounting software, stock management or an ordering system via an app. This helps you avoid entering data twice, reduce errors and save time in daily work.

A practical example:

Imagine your café uses a POS system to handle orders. At the same time, you use accounting software to keep track of your finances. With an API integration between the two systems, the day's sales can be transferred automatically to the accounting software. That way you avoid manually exporting and entering figures, and you minimise the risk of errors.

Why is it important to know about APIs?

As a restaurateur or café owner, you may have many systems in play – each solving a specific task. APIs tie these systems together so they work as one combined tool. That can mean a more efficient working day, fewer errors and a better customer experience. Knowing about APIs also gives you a better understanding of what is possible when you choose and combine systems.

How does Flexybox use APIs?

Flexybox offers an API that lets you integrate your Flexybox POS or booking system with third-party solutions. This means you can, for example, connect the system to accounting software, a CRM system or third-party ordering solutions and automate processes. The result is a more streamlined setup where the systems you use every day work together without manual handling.
