An API specification is a document or standard that explains how to create or use a connection or interface. A computer system that follows this standard is said to have an API. The term API can refer to either the specification or the actual implementation.

Generally, API is just a set of instructions programs use to send/receive information with each other. By setting an API, you’re allowing your software to connect with other software with a purpose of your choosing.

For example, you would be using an API to send and receive information about leads.
