An Api is a connection between computers or computer programs. According to the layman's terms:

API is a Messenger between user and web-server. Let's understand this with a very famous Non programming example: Say ,you visit a restaurant, the waiter presents you with the menu card. You decide what you want to eat. It could be pizza🍕, pasta🍝 or fries🍟. The waiter takes down your order and then share it with the chefs.Once your food is ready, he delivers the meal right to you .

Here in the above diagram

You is the 'user'

Waiter is the 'API'

Kitchen is the 'Web-server'
