API Integration

TeamDay's powerful API integration capabilities allow you to connect your AI agents with external services, databases, and applications to extend their functionality and automate complex workflows.

Understanding API Integrations

What Are API Integrations?

API integrations allow your AI agents to:

  • Connect to external services and databases
  • Pull data from third-party applications
  • Push information to other systems
  • Automate cross-platform workflows
  • Extend agent capabilities beyond built-in tools

Types of Integrations

  • REST APIs: Standard HTTP-based integrations
  • GraphQL APIs: Query-based data integrations
  • Webhooks: Real-time event-driven integrations
  • Database Connections: Direct database access
  • File System Access: Local and cloud file operations

Setting Up API Integrations

Prerequisites

Before setting up integrations:

  • Valid API credentials from the target service
  • Understanding of the target API documentation
  • Appropriate permissions in TeamDay
  • Knowledge of data formats and endpoints

Basic Integration Setup

1. Authentication Configuration

{
  "type": "oauth2",
  "client_id": "your_client_id",
  "client_secret": "your_client_secret",
  "scope": "read write",
  "token_url": "https://api.example.com/oauth/token"
}

2. API Endpoint Configuration

{
  "base_url": "https://api.example.com/v1",
  "headers": {
    "Content-Type": "application/json",
    "Authorization": "Bearer {token}"
  },
  "timeout": 30
}

3. Data Mapping

Define how data flows between systems:

{
  "input_mapping": {
    "agent_field": "api_parameter",
    "user_input": "request_body.message"
  },
  "output_mapping": {
    "api_response.data": "agent_knowledge",
    "api_response.status": "operation_result"
  }
}

Common Integration Patterns

CRM Integration

Connect to customer relationship management systems:

Salesforce Integration

// Retrieve customer information
const getCustomer = async (customerId) => {
  const response = await api.get(`/sobjects/Account/${customerId}`);
  return response.data;
};

// Update customer record
const updateCustomer = async (customerId, data) => {
  return await api.patch(`/sobjects/Account/${customerId}`, data);
};

HubSpot Integration

// Get contact details
const getContact = async (email) => {
  const response = await api.get(`/contacts/v1/contact/email/${email}/profile`);
  return response.data;
};

Project Management Integration

Asana Integration

// Create new task
const createTask = async (taskData) => {
  return await api.post('/tasks', {
    data: {
      name: taskData.title,
      notes: taskData.description,
      projects: [taskData.projectId]
    }
  });
};

Jira Integration

// Create issue
const createIssue = async (issueData) => {
  return await api.post('/rest/api/3/issue', {
    fields: {
      project: { key: issueData.projectKey },
      summary: issueData.summary,
      description: issueData.description,
      issuetype: { name: 'Task' }
    }
  });
};

Communication Platform Integration

Slack Integration

// Send message to channel
const sendMessage = async (channel, message) => {
  return await api.post('/chat.postMessage', {
    channel: channel,
    text: message,
    as_user: true
  });
};

Microsoft Teams Integration

// Send adaptive card
const sendAdaptiveCard = async (teamId, channelId, card) => {
  return await api.post(
    `/teams/${teamId}/channels/${channelId}/messages`,
    {
      body: {
        contentType: 'application/vnd.microsoft.card.adaptive',
        content: card
      }
    }
  );
};

Data Sources and Databases

Database Integrations

PostgreSQL Connection

{
  "type": "postgresql",
  "host": "localhost",
  "port": 5432,
  "database": "teamday_data",
  "username": "api_user",
  "password": "secure_password",
  "ssl": true
}

MongoDB Integration

{
  "type": "mongodb",
  "connection_string": "mongodb://user:pass@host:port/database",
  "database": "teamday_data",
  "collection": "agent_knowledge"
}

Cloud Storage Integration

AWS S3 Integration

// Upload file to S3
const uploadFile = async (bucketName, fileName, fileData) => {
  return await s3.upload({
    Bucket: bucketName,
    Key: fileName,
    Body: fileData,
    ContentType: 'application/octet-stream'
  }).promise();
};

Google Drive Integration

// Create file in Google Drive
const createFile = async (fileName, content, folderId) => {
  return await drive.files.create({
    requestBody: {
      name: fileName,
      parents: [folderId]
    },
    media: {
      mimeType: 'text/plain',
      body: content
    }
  });
};

Security Best Practices

Authentication Security

  • Use OAuth 2.0 when available
  • Store credentials securely (never in code)
  • Implement token refresh mechanisms
  • Use least-privilege access principles

Data Protection

  • Encrypt sensitive data in transit and at rest
  • Implement proper input validation
  • Use HTTPS for all API communications
  • Regularly rotate API keys and tokens

Access Control

  • Implement role-based access control
  • Monitor and log API usage
  • Set up rate limiting and quotas
  • Use IP whitelisting when appropriate

Error Handling and Resilience

Common Error Scenarios

  • Network timeouts and connectivity issues
  • Authentication and authorization failures
  • Rate limiting and quota exceeded
  • Data format and validation errors

Retry Mechanisms

const retryWithBackoff = async (apiCall, maxRetries = 3) => {
  for (let i = 0; i < maxRetries; i++) {
    try {
      return await apiCall();
    } catch (error) {
      if (i === maxRetries - 1) throw error;
      await new Promise(resolve => 
        setTimeout(resolve, Math.pow(2, i) * 1000)
      );
    }
  }
};

Circuit Breaker Pattern

class CircuitBreaker {
  constructor(threshold = 5, timeout = 60000) {
    this.threshold = threshold;
    this.timeout = timeout;
    this.failureCount = 0;
    this.state = 'CLOSED';
    this.nextAttempt = Date.now();
  }

  async call(apiFunction) {
    if (this.state === 'OPEN') {
      if (Date.now() < this.nextAttempt) {
        throw new Error('Circuit breaker is OPEN');
      }
      this.state = 'HALF_OPEN';
    }

    try {
      const result = await apiFunction();
      this.onSuccess();
      return result;
    } catch (error) {
      this.onFailure();
      throw error;
    }
  }

  onSuccess() {
    this.failureCount = 0;
    this.state = 'CLOSED';
  }

  onFailure() {
    this.failureCount++;
    if (this.failureCount >= this.threshold) {
      this.state = 'OPEN';
      this.nextAttempt = Date.now() + this.timeout;
    }
  }
}

Testing and Validation

Integration Testing

  • Test authentication flows
  • Validate data mapping and transformations
  • Verify error handling scenarios
  • Test rate limiting behavior

Monitoring and Logging

// API call logging middleware
const apiLogger = async (request, response) => {
  const startTime = Date.now();
  
  try {
    const result = await makeApiCall(request);
    const duration = Date.now() - startTime;
    
    console.log({
      type: 'api_success',
      endpoint: request.url,
      method: request.method,
      duration: duration,
      status: response.status
    });
    
    return result;
  } catch (error) {
    const duration = Date.now() - startTime;
    
    console.error({
      type: 'api_error',
      endpoint: request.url,
      method: request.method,
      duration: duration,
      error: error.message,
      stack: error.stack
    });
    
    throw error;
  }
};

Performance Optimization

Caching Strategies

  • Implement response caching for frequently accessed data
  • Use appropriate cache expiration policies
  • Consider distributed caching for scalability
  • Implement cache invalidation mechanisms

Batch Operations

// Batch API requests
const batchRequests = async (requests, batchSize = 10) => {
  const results = [];
  
  for (let i = 0; i < requests.length; i += batchSize) {
    const batch = requests.slice(i, i + batchSize);
    const batchResults = await Promise.all(
      batch.map(request => makeApiCall(request))
    );
    results.push(...batchResults);
  }
  
  return results;
};

Connection Pooling

  • Use connection pooling for database integrations
  • Implement proper connection lifecycle management
  • Monitor connection pool metrics
  • Configure appropriate pool sizes

Advanced Integration Patterns

Event-Driven Architecture

  • Implement webhook receivers for real-time updates
  • Use message queues for asynchronous processing
  • Set up event streaming for large-scale integrations
  • Implement event sourcing patterns when appropriate

Microservices Integration

  • Design APIs with microservices principles
  • Implement service discovery mechanisms
  • Use API gateways for request routing
  • Implement distributed tracing

GraphQL Integration

// GraphQL query example
const getCustomerData = async (customerId) => {
  const query = `
    query GetCustomer($id: ID!) {
      customer(id: $id) {
        id
        name
        email
        orders {
          id
          date
          total
        }
      }
    }
  `;
  
  return await graphqlClient.request(query, { id: customerId });
};
