jsonify a Dictionary

Return JSON with the correct content type.

Why JSON Matters

When your app powers an API, it sends data, not pages. The universal format for that data is JSON, and Flask makes it easy. 🚀

Strings Are Not Enough

Returning a plain string works for a webpage, but an API client expects structured data it can parse. That is exactly where jsonify steps in.
