   • Connect to CRM systems (Salesforce, HubSpot) 📇
   • Pull data from APIs (Weather, Stock) 🌦️📈
   • Interface with databases (PostgreSQL, MongoDB) 🗄️

🛠️ Practical Implementation Guide

Step 1: Setting Up Your First AI Agent

1. Drag the AI Agent node into your workflow
2. Configure your AI provider (OpenAI, Anthropic, etc.)
3. Design your prompt template:

   
   Analyze the following customer query:
   {input}

Determine:

1. Product category [Electronics|Home|Fashion]
2. Urgency level [1-5]
3. Suggested response template

Step 2: Connecting External Tools

Example: Auto-create CRM tickets from emails

Email Trigger → AI Analysis → 
IF Urgency > 3 THEN Create High-Priority Ticket
ELSE Add to General Queue

Step 3: Advanced Chaining

Combine multiple AI agents for complex workflows:

Customer Message → Sentiment Analysis → 
→ Product Identification → 
→ Knowledge Base Search → 
→ Draft Response
