Binance strives to give its customers an amazing API feature for trade. API, or application programming interfaces, are a collection of subroutine meanings, rules of communication, and items for the construction of software.
In the case of Binance, APIs help simplify programming by abstracting the underlay implements and only showing things or protocols the creator needs.
These interfaces help simplify things for the average customer and help regulate transactions which help keep everything safe and easier for all of the parties involved. Currently, Binance has an API running for clients who are using their system of authorized requests.
