API serves as a bridge between you and a server enabling them to communicate.
Example: imagine a University & a Recruiting Company communicating together, when a student gradate the University would share the information about that student with the Recruiting Company, In this case they use the API for communication, this way the Recruiting Company gets the latest data directly from the University.
- API request, from the Recruiting Company side.
- API response, from the University side.
API is important if you want to integrate an AI model like GPT from OpenAI into your product, this connection is essential to send requests & receive responses from OpenAI's services.
