# Integration Catalog Overview

> Explore n8n's 500+ built-in integrations for workflow automation with APIs, databases, and services

# Integration Catalog Overview

n8n provides a comprehensive catalog of 500+ built-in integrations that enable you to connect and automate workflows across your entire tech stack. From popular SaaS applications to databases, APIs, and internal services, n8n nodes make automation accessible and powerful.

## What are n8n Integrations?

Integrations in n8n are implemented as **nodes** - modular building blocks that connect to external services and perform specific operations. Each node is pre-configured with:

* **Built-in authentication** - OAuth2, API keys, JWT, and more
* **Pre-defined operations** - Common actions ready to use
* **Type-safe parameters** - Validated inputs with helpful descriptions
* **Error handling** - Automatic retries and error management
* **Resource locators** - Smart selectors for lists, IDs, and URLs

## Node Architecture

All n8n integrations follow a consistent architecture:

<Tabs>
  <Tab title="Declarative Nodes">
    Declarative nodes use configuration-based routing without custom code:

    ```typescript theme={null}
    {
      displayName: 'Okta',
      name: 'okta',
      icon: 'file:okta.svg',
      group: ['transform'],
      description: 'Consume Okta API',
      requestDefaults: {
        baseURL: '={{$credentials.url}}/api/v1',
        headers: {
          'Content-Type': 'application/json',
        },
      },
      routing: {
        request: {
          method: 'GET',
          url: '/users',
        },
      },
    }
    ```

    **Best for:** REST API integrations with standard patterns
  </Tab>

  <Tab title="Programmatic Nodes">
    Programmatic nodes implement custom logic in the execute function:

    ```typescript theme={null}
    async execute(this: IExecuteFunctions) {
      const items = this.getInputData();
      const returnData: INodeExecutionData[] = [];
      
      for (let i = 0; i < items.length; i++) {
        const operation = this.getNodeParameter('operation', i);
        
        if (operation === 'send') {
          // Custom logic for sending messages
          const message = this.getNodeParameter('message', i);
          // API call and processing
        }
      }
      
      return [returnData];
    }
    ```

    **Best for:** Complex operations, custom data processing
  </Tab>

  <Tab title="Versioned Nodes">
    Versioned nodes support multiple API versions:

    ```typescript theme={null}
    export class Slack extends VersionedNodeType {
      constructor() {
        const nodeVersions = {
          1: new SlackV1(baseDescription),
          2: new SlackV2(baseDescription),
          2.4: new SlackV2(baseDescription),
        };
        super(nodeVersions, baseDescription);
      }
    }
    ```

    **Best for:** Maintaining backward compatibility
  </Tab>
</Tabs>

## Finding the Right Integration

### By Use Case

<Accordion title="Data Synchronization">
  Use **Google Sheets**, **Airtable**, **Notion**, or database nodes to sync data between systems. Combine with **Schedule Trigger** for periodic syncs.
</Accordion>

<Accordion title="Notification Workflows">
  Use **Slack**, **Discord**, **Microsoft Teams**, or **Email Send** nodes with trigger nodes to create alert systems.
</Accordion>

<Accordion title="Lead Management">
  Connect **HubSpot**, **Salesforce**, or **Pipedrive** with form submission triggers to automate lead capture and follow-up.
</Accordion>

<Accordion title="API Integration">
  Use the **HTTP Request** node for custom APIs, or find a dedicated node for better authentication and error handling.
</Accordion>

<Accordion title="File Processing">
  Use **Google Drive**, **Dropbox**, **AWS S3**, or **FTP** nodes with file manipulation nodes for automated file workflows.
</Accordion>

### By Authentication Type

Different integrations support different authentication methods:

* **OAuth2** - Google, Microsoft, Slack, GitHub, HubSpot
* **API Key** - SendGrid, OpenAI, Stripe, Twilio
* **Basic Auth** - Many REST APIs, LDAP, Jenkins
* **JWT** - Custom enterprise APIs
* **Database Credentials** - PostgreSQL, MySQL, MongoDB

## Building Custom Integrations

When a dedicated node doesn't exist:

1. **HTTP Request Node** - For RESTful APIs
2. **GraphQL Node** - For GraphQL endpoints
3. **Code Node** - For complex custom logic (use as last resort)
4. **Community Nodes** - Check npm for community-built integrations
