# How do you organize documentation for a large API with multiple resources and versions?

Organizing documentation for a **large API with multiple resources and versions** requires a structured, scalable, and user-friendly approach. Here’s how to do it effectively:

## 1. Top-Level Structure by API Version

Create a clear versioning hierarchy:

```plaintext
/docs/
  ├── v1/
  ├── v2/
  └── v3/
```

Each version should have:

- A changelog
- Deprecated/legacy notices (if any)
- Unique base URL if applicable

## Example:

```plaintext
https://api.example.com/v1/
https://api.example.com/v2/
```

## 2. Group by Resource or Feature Domain

Within each version, organize endpoints by **resource groups** or **functional modules**:

```plaintext
/v2/
  ├── authentication/
  ├── users/
  ├── posts/
  ├── comments/
  ├── analytics/
```

Each section should contain:

- Overview of the resource
- List of endpoints
- Use case examples

## 3. Sidebar or Navigation Menu

Use a persistent **left-hand navigation menu** for web-based docs:

- Expandable sections for each resource group
- Clearly labeled versions
- Breadcrumb navigation

## 4. Use Tabs or Toggle for Version Switching

Let users switch between versions of the same endpoint:

```plaintext
[ v1 | v2 | v3 ]
GET /users/{id}
```

Use visual cues (badges like “Deprecated”, “Beta”) to help users navigate the lifecycle.

## 5. Consistent Layout Per Endpoint

Maintain the same format across all endpoints:

- HTTP method + URL
- Description
- Parameters (path, query, header, body)
- Request example
- Response example
- Error codes

## 6. Interactive Tools Per Version

- **Swagger/OpenAPI UI** per version
- **Postman collections** organized by version and feature

## 7. Dedicated Changelog and Migration Guides

- List breaking changes per version
- Include upgrade paths and examples

## 8. Search and Filtering

- Search by resource, keyword, or endpoint
- Filters by version, method (GET/POST), or status (deprecated)

## 9. Authentication, Errors, and Common Concepts as Shared Pages

Avoid duplication—have shared reference docs:

```plaintext
/v2/
  ├── guides/
  │    ├── authentication.md
  │    ├── error-handling.md
  │    ├── rate-limiting.md
```

## 10. Collapsible Sections for Large Payloads

Use collapsible/expandable sections for:

- JSON payloads
- Long parameter lists
- Multiple examples (valid/invalid)

## Bonus Tips

- Use **open standards** like OpenAPI/Swagger
- Provide downloadable API specs (YAML/JSON)
- Keep deprecated versions available but clearly marked

Organizing documentation for a **large API with multiple resources and versions** requires a structured, scalable, and user-friendly approach. Here’s how to do it effectively:

## 5. Consistent Layout Per Endpoint

Maintain the same format across all endpoints:

- HTTP method + URL

- Parameters (path, query, header, body)
- Request example
- Response example
- Error codes

## 6. Interactive Tools Per Version

- **Swagger/OpenAPI UI** per version
- **Postman collections** organized by version and feature

## 7. Dedicated Changelog and Migration Guides
