API Integration

API Integration in CodeNull allows you to create powerful backend services that drive your web application’s functionality. Our API Dashboard provides intuitive tools for designing and documenting your APIs without writing complex backend code.

​
The API Integration Process

1

Define API Requirements

Identify what your application needs from the backend:
  • Data operations needed
  • Authentication requirements
  • External service integrations
  • Performance considerations
2

Design API Endpoints

Create the structure of your API:
  • Define resources and routes
  • Determine request/response formats
  • Plan parameter validation
  • Document endpoint purposes
3

Implement Business Logic

Add the functionality behind your API:
  • Data processing rules
  • Conditional operations
  • Data transformations
  • Error handling
4

Configure Security

Secure your API endpoints:
  • Authentication methods
  • Authorization rules
  • Rate limiting
  • Input validation
5

Test & Debug

Verify your API works correctly:
  • Test various inputs
  • Validate responses
  • Check error scenarios
  • Optimize performance

​
API Dashboard Tools

CodeNull’s API Dashboard includes several tools to streamline API development:

​
API Designer

The visual API Designer helps you create endpoints and define their structures:

Key features:
  • Visual endpoint creation
  • Request/response schema builder
  • Parameter definition
  • Automatic validation rules

​
Logic Builder

The Logic Builder allows you to create backend functionality with a visual flow interface:

Features include:
  • Visual programming blocks
  • Database operation nodes
  • Conditional processing
  • External service connectors

​
Common API Patterns

CodeNull provides templates for common API patterns:

CRUD Operations

Create, Read, Update, Delete endpoints for your data models

Authentication

User login, registration, and token-based authentication

File Operations

Upload, download, and process files and media

Search & Filtering

Advanced query endpoints with filtering, sorting, and pagination

External Integrations

Connect to third-party services and APIs

Webhooks

Event-based notification endpoints

​
Best Practices

Design your API to be resource-oriented and follow RESTful principles for better maintainability and developer experience.
  • Use consistent naming: Follow a consistent pattern for endpoint URLs
  • Implement proper status codes: Return appropriate HTTP status codes for different scenarios
  • Version your API: Include version information in your API paths
  • Provide detailed error messages: Include helpful error information for debugging
  • Optimize response payloads: Return only the data that’s needed

​
API Security

CodeNull provides built-in security features for your APIs:
  • JWT (JSON Web Tokens)
  • API keys
  • OAuth 2.0
  • Session-based authentication
  • Role-based access control
  • Resource-based permissions
  • Attribute-based rules
  • Custom policy enforcement
  • Input validation
  • Rate limiting
  • CORS configuration
  • Request throttling
  • IP whitelisting/blacklisting

Next Steps

Once you’ve configured your API endpoints, you’re ready to move on to Database Configuration to set up the data models and relationships that your API will use.
