What is postman?

Postman is like a super friendly helper that sends messages between computers.

Imagine you have a best friend who lives next door. You want to send them a note, but instead of writing it on paper and putting it in their mailbox, you use a special app, kind of like a robot messenger. That’s what Postman does, but for computers.

Postman helps computers talk to each other by sending messages called requests and getting answers called responses. It's like when you ask your friend a question, and they answer back, only this happens between two computers.

For example, if you want to check the weather on your phone, your phone sends a message to a weather website, just like how you might send a note to your friend. Postman helps make that message clear so the website knows what you're asking for.

People use Postman because it makes it easy to test and build apps or websites, just like how you might use a pencil and paper to practice writing letters to your friends. It’s a fun tool that helps computers understand each other better!
