Typical structure includes:

For complex logic (e.g., "Users can only update their own posts"), create a custom Policy.

Use for repeated data structures. If you have a "SEO Meta Data" block used across Pages, Blog Posts, and Products, create a Component. This keeps your API schema DRY (Don't Repeat Yourself).

| Topic | Why It Matters | Likely Missing? | |-------|----------------|------------------| | | Strapi doesn’t enforce versions; PDF might skip URI versioning ( /v1/products ) or custom headers. | ❌ Yes | | Rate limiting & throttling | Essential for public APIs, but Strapi requires external middleware (e.g., express-rate-limit ). | ❌ Yes | | Hypermedia/HATEOAS | Strapi returns JSON by default; no built-in HAL/JSON-LD support. PDF unlikely to cover. | ❌ Yes | | Webhook design | Strapi supports webhooks, but best practices (idempotency, retries, signing) often omitted. | ⚠️ Partial | | OpenAPI/Swagger export | Strapi lacks native OpenAPI generation (community plugins exist). PDF may mention but not deep-dive. | ⚠️ Partial | | Real-time (WebSockets) | Not native; requires custom server or Socket.io integration. PDF likely avoids. | ❌ Yes |

This text can be used as a starting point to create a PDF guide or tutorial on designing web APIs with Strapi. You can add more details, examples, and screenshots to make it more comprehensive and easy to follow.

Designing an API with Strapi is more than just defining fields in a UI. It requires a thoughtful approach to data relationships, strict permission settings, and optimized query strategies.

You want to calculate a readingTime field whenever an Article is created or updated, but you don't want the user to input it manually.

Explains how to install @strapi/plugin-graphql and auto-generate a GraphQL schema from content types — useful for teams preferring GraphQL over REST.

Design your API to allow the frontend to handle pagination ( pagination[start]=0&pagination[limit]=10 ) to prevent overloading the client with thousands of records.

Sometimes the default JSON output isn't perfect. Strapi allows you to manipulate data using in the model files.

When designing your API, adhere to these principles:
