The Top Useful APIs for Marketers

If you are a Data-Driven Marketer that uses analyzed data to determine what or how to market a product, then the right APIs can simplify the process.

An API (Application Programming Interface) is an interface that dictates how different software should communicate with each other. It acts like a translator between software by breaking down and interpreting data so that a 3rd party can understand it. With so much free applications that collect data on the market now, there is a great opportunity available to take advantage to make your goals easier. APIs are a little challenging to use. They will require you to understand some amount of programming and understand how software architectures work.
