Why do we use APIs and not directly access the data from the servers?ĪPIs make the task of developers easier by removing the need to create every service from scratch.
CLUBHOUSE API POSTMAN SOFTWARE
The above depiction shows us how in the Software Development World, the client (the person requiring the data), sends a request which is taken by the API to the Server (where the data is stored) and the action is performed accordingly. Similarly, the role of an API is to act as the middleman for the communicator between softwares. The function of the waiter is to communicate to you whether there is a stock of ice-cream or not, if there is, he will bring it for you.
