# How to Perform REST API Requests and Debugging Using cURL CLI?

cURL is one of the most widely used command-line tools for transferring data with URLs. It is ideal for quick REST API testing and debugging straight from the CMD terminal.

## How to send custom HTTP POST and GET requests using cURL?

Below are common cURL commands used for testing RESTful services:

### 1. GET Request with Headers

```
curl -X GET "https://api.example.com/v1/users" \
  -H "Accept: application/json" \
  -H "Authorization: Bearer YOUR_TOKEN"
```

### 2. POST Request with JSON Body

```
curl -X POST "https://api.example.com/v1/users" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "John Doe",
    "email": "john@example.com"
  }'
```

Using the `-i` flag includes HTTP response headers in the output, which helps verify status codes and caching policies.
