API Integration Example

Comprehensive API integration patterns with external services, error handling, and data synchronization

API Integration Example

This example demonstrates how to integrate RCrewAI crews with external APIs and services. We’ll build a comprehensive system that handles API authentication, data synchronization, error handling, and service orchestration across multiple external platforms.

Overview

Our API integration system includes:

• CRM Integration - Sync customer data with Salesforce/HubSpot
• Payment Processing - Handle transactions with Stripe/PayPal
• Email Marketing - Automate campaigns with Mailchimp/SendGrid
• Analytics Integration - Push data to Google Analytics/Mixpanel
• Social Media APIs - Manage posts across Twitter/LinkedIn/Facebook

Complete Implementation

require 'faraday'
require 'json'
require 'base64'

# Configure RCrewAI for API integration tasks
RCrewAI.configure do |config|
  config.llm_provider = :openai
  config.temperature = 0.3  # Lower temperature for precise API operations
end
