curl Basics
GET Request
curl https://api.example.com/users
curl -s https://api.example.com/users # Silent
curl -i https://api.example.com/users # Include headers
POST Request
# JSON body
curl -X POST https://api.example.com/users \
-H "Content-Type: application/json" \
-d '{"name":"John","email":"john@example.com"}'
# From file
curl -X POST https://api.example.com/users \
-H "Content-Type: application/json" \
-d @data.json
Headers & Auth
# Custom header
curl -H "Authorization: Bearer token123" https://api.example.com
# Basic auth
curl -u username:password https://api.example.com
# Multiple headers
curl -H "Content-Type: application/json" \
-H "X-API-Key: key123" \
https://api.example.com
Other Methods
# PUT
curl -X PUT https://api.example.com/users/1 \
-H "Content-Type: application/json" \
-d '{"name":"Updated"}'
# PATCH
curl -X PATCH https://api.example.com/users/1 \
-d '{"status":"active"}'
# DELETE
curl -X DELETE https://api.example.com/users/1
File Upload
# Form upload
curl -X POST https://api.example.com/upload \
-F "file=@photo.jpg" \
-F "description=My photo"
# Binary
curl -X POST https://api.example.com/upload \
--data-binary @file.bin \
-H "Content-Type: application/octet-stream"
Useful Options
-v # Verbose (debug)
-s # Silent
-o file # Output to file
-O # Save with remote filename
-L # Follow redirects
-k # Ignore SSL errors
-w '\n' # Add newline after output
--max-time 10 # Timeout in seconds
HTTPie (Friendlier Alternative)
GET Request
http https://api.example.com/users
http GET api.example.com/users # Explicit GET
POST Request
# JSON (default)
http POST api.example.com/users name=John email=john@example.com
# String vs other types
http POST api.example.com/users name=John age:=30 active:=true
Headers & Auth
# Header
http api.example.com Authorization:"Bearer token"
# Basic auth
http -a user:pass api.example.com
# Bearer auth
http api.example.com "Authorization: Bearer token"
Output Control
http -h api.example.com # Headers only
http -b api.example.com # Body only
http -p Hh api.example.com # Request headers
Common Patterns
Test Response Code
# curl
status=$(curl -s -o /dev/null -w "%{http_code}" https://api.example.com)
echo "Status: $status"
# Check if successful
if curl -s -f https://api.example.com > /dev/null; then
echo "Success"
fi
Pretty Print JSON
curl -s https://api.example.com | jq .
curl -s https://api.example.com | python -m json.tool
Save Response & Headers
curl -D headers.txt -o response.json https://api.example.com
Retry on Failure
curl --retry 3 --retry-delay 2 https://api.example.com
Timing Info
curl -w "Time: %{time_total}s\n" -o /dev/null -s https://api.example.com
GraphQL
curl -X POST https://api.example.com/graphql \
-H "Content-Type: application/json" \
-d '{"query": "{ users { id name } }"}'
Debug
# Verbose output
curl -v https://api.example.com
# Trace (very detailed)
curl --trace - https://api.example.com
# Show only response headers
curl -I https://api.example.com
