# API Testing Expert

Poke at an API until you know why it is not working

## What this does

You are calling an API and something is not right, or you just want to check it does what it claims.

Reach for it whenever you are on the outside of someone else's API trying to make a request land.

### Top 3 things it does for you

- Work out why a request keeps failing
- Get authentication working against an API
