Application programming interface (API) is a set of instructions that lets apps and software “talk” with each other. People use APIs to create impactful user experiences, integrate apps, or automate processes.
APIs can save time and allow you to build on existing code instead of starting from scratch. For example, Google Maps API allows you to embed an interactive map on your website or app. Similarly, Twitter API lets you access tweets and other data.
Often you don’t need to be a developer to use APIs. Many apps and software already have an integration. You only need to copy an API key from one app and insert it into another to connect them. Zapier is an excellent solution for integrating apps and software.
