What is Contentful and how does it differ from traditional CMS platforms?

beginner

Contentful is a headless CMS that provides content infrastructure through APIs. Unlike traditional CMS platforms (WordPress, Drupal) that couple content with presentation, Contentful separates them - storing content in raw format and delivering it via REST or GraphQL APIs. This allows developers to use any language/framework and display content across multiple channels (web, mobile, IoT).

Explain the concept of "Spaces" in Contentful.

beginner

A Space is Contentful's top-level container that holds all content, media assets, and settings. Each space is isolated and contains its own content types, entries, assets, and locales. Organizations use different spaces for different projects or environments (dev, staging, production). Each space has a unique Space ID and specific API keys for access.

What are Content Types and how do you define them?

beginner

Content Types are schemas that define content structure - like templates specifying what fields entries should have. They use field types like Text, Number, Date, Boolean, Media, Reference, JSON Object. Example: A "Blog Post" content type might have title (Short Text), body (Rich Text), author (Reference), and publishDate (Date) fields.

What are the main APIs provided by Contentful?

beginner

Contentful provides four main APIs:

Content Delivery API (CDA): Retrieves published content (read-only, cached)
Content Preview API: Retrieves draft/unpublished content
Content Management API (CMA): Creates, updates, deletes content programmatically
Images API: Transforms images on-the-fly

Each has different rate limits and caching behaviors.

How do you authenticate with Contentful APIs?

beginner

Contentful uses API keys for authentication:

CDA: Content Delivery API key (read-only published content)
Preview API: Content Preview API key (read-only all content)
CMA: Personal Access Tokens or OAuth (read-write access)

Example: Authorization: Bearer YOUR_ACCESS_TOKEN

What is the difference between Entries and Assets in Contentful?

beginner

Entries are instances of Content Types containing structured content (text, numbers, dates, references) - your actual content like blog posts or products. Assets are binary files (images, videos, PDFs) stored separately and referenced through Media fields, with their own metadata.

Explain the differences between Symbol and Text field types.
