API stands for Application Programming Interface, which is a software intermediary that allows two applications to talk to each other.
Each time you use an app like Facebook, send an IM or check the weather, you’re using an API.
When you use an application on your mobile phone, the application connects to the Internet and sends data to a server. The server then retrieves that data, interprets it, performs the necessary actions and sends it back to your phone. The application then interprets that data and presents you with the information you wanted in a readable way. This is what an API is - all of this happens via API.
Imagine you’re sitting at a table in a restaurant with a menu of choices to order from. The kitchen is the part of the “system” that will prepare your order. What is missing is the critical link to communicate your order to the kitchen and deliver your food back to your table. That’s where the waiter or API comes in. The waiter is the messenger – or API – that takes your request or order and tells the kitchen – the system – what to do. Then the waiter delivers the response back to you; in this case, it is the food.
The Connection of multiple APIs is what we refer to when we talk about bridges. At Drive, we create bridges between Facebook, Marketing Milk, and the systems our clients use that contain their customer data. This allows us to track performance of our marketing campaigns and show that performance on the Marketing Milk dashboard in a way that is useful to the pods internally, and to the clients externally.
