FastAPI Todo App Tutorial #5 | Fetch Todos by Category Using Query Parameter

Welcome to another video of the FastAPI Series! 🌙 In this session, we’re continuing our Todo App using FastAPI and building an API to fetch todos by category using a Query Parameter. 🔍📂 Filtering data using query parameters is a very common real‑world requirement, and this video shows how to implement it cleanly in FastAPI. By the end of this lesson, you’ll understand: ✅ How to create a GET API that filters todos by category ✅ How to use Query Parameters in FastAPI ✅ The difference between Path Parameters vs Query Parameters ✅ How FastAPI automatically validates query parameters ✅ How to handle optional and required query values ✅ How to test query‑based filtering using Swagger UI ✅ How this API fits into a complete Todo CRUD workflow With hands‑on coding, clear explanations, and real API demos, you’ll gain the confidence to build flexible and user‑friendly APIs using FastAPI. 🚀 💬 Don’t forget to Like, Subscribe, and Comment what you learned today — your support keeps these coding lessons going strong! ✨ Before you sleep, make sure you’ve learned something new. ✨ #FastAPISeries #FastAPI #TodoApp #QueryParameters #FilterAPI #APIDevelopment #Python #LearnFastAPI #FastAPITutorial #PythonTutorial #PythonForBeginners #BackendDevelopment #SwaggerUI #PythonProgramming #CodeBeforeYouSleep #YashJain
