Response Handling

• List endpoints return arrays
• Pagination: check Link header for rel="next"
• Dates are ISO 8601 (UTC)
• Use --max-time 30 for slow endpoints

Parse with jq:

curl -s ... | jq '.[] | {name: .name, due: .due_at}'

Or Python if jq unavailable:

curl -s ... | python3 -c "import sys,json; data=json.load(sys.stdin); print(json.dumps(data, indent=2))"

Tips

• Course IDs appear in todo/assignment responses
• File download URLs are in the url field of file objects
• Always include per_page=50 to get more results (default is often 10)
