I normally find API very confusing. But lately I have been researching about API and read a lot of articles about different implementations. I have also tried out public API in postman. Most API are free but some require a auth parameters. I am trying to understand everything about API because that is a vital part of everything. I find difficulty with understanding pagination with API. I find myself lost when I need to explain API to somebody who doesn't know. I also find difficulty in knowing the pros and cons of REST API against GraphQL.
