An API (Application Progamming Interface) is a set of clearly defined methods of communication between various software component.
The API make it easier for developers to link our data to your website.
You can see an API like a waiter in a restaurant who talks to the customer, takes their order and passes it on to the kitchen.
In our case, your existing system is the customer and our feedback software is the kitchen. Because these programs are not normally able to communicate with each other, an API is needed to act as an intermediary.
So you can make use of the features of Feedback Company in the programs you’re already using.
