Third-Party APIs Quiz: Test Your Knowledge of Web Development

📚 Quick Study Guide

• 🔑 API (Application Programming Interface): A set of rules and protocols that allows different software applications to communicate and exchange data.
• 🌐 Third-Party API: An API provided by a service that is external to your own application or system.
• 📡 Common API Uses:
  • 📍 Integrating maps (e.g., Google Maps API).
  • ☁️ Utilizing cloud storage (e.g., AWS S3 API).
  • ✉️ Sending emails (e.g., SendGrid API).
  • 💰 Processing payments (e.g., Stripe API).
• 🛡️ Authentication Methods:
  • 🗝️ API Keys: Unique identifiers used to authenticate requests.
  • 🔒 OAuth: An open standard for access delegation, often used for user authorization.
  • 📜 JWT (JSON Web Tokens): A compact, URL-safe means of representing claims to be transferred between two parties.
• ⚙️ API Request Methods (HTTP Verbs):
  • ➡️ GET: Retrieves data.
  • ➕ POST: Creates new data.
  • ✏️ PUT: Updates existing data.
  • ❌ DELETE: Deletes data.
• 🚦 Status Codes:
  • 200 OK: Request was successful.
  • 400 Bad Request: The server could not understand the request.
  • 401 Unauthorized: Authentication is required.
  • 403 Forbidden: The server understood the request, but refuses to authorize it.
  • 404 Not Found: The requested resource could not be found.
  • 500 Internal Server Error: A generic error occurred on the server.
• 🧮 Rate Limiting: A mechanism to limit the number of requests a user can make in a given time period to prevent abuse and ensure fair usage.
