Overview

Concrete adapter for integrating Zapier Actions API with CrewAI provided by CrewAI.

Description

This module implements two classes: ZapierActionTool and ZapierActionsAdapter. The ZapierActionsAdapter class discovers available Zapier actions from a user's account via the Zapier Actions API and dynamically generates ZapierActionTool instances for each action. Each tool is created with a dynamically generated Pydantic schema based on the action's parameters. The ZapierActionTool class extends BaseTool and executes individual Zapier actions by sending POST requests to action-specific endpoints. It supports a special instructions parameter for natural language action execution and formats other parameters with Zapier's "value" and "mode" (guess) structure. API authentication is handled via the x-api-key header, with the key sourced from the constructor parameter or the ZAPIER_API_KEY environment variable.

Usage

Import and instantiate ZapierActionsAdapter with your Zapier API key to automatically discover and create CrewAI tools for all configured Zapier actions. This enables agents to interact with 5000+ app integrations (Gmail, Slack, Salesforce, Google Sheets, etc.) through Zapier's automation platform.

Usage Examples

Basic Usage

from crewai_tools.adapters.zapier_adapter import ZapierActionsAdapter

# Initialize with API key (or set ZAPIER_API_KEY env var)
adapter = ZapierActionsAdapter(api_key="your-zapier-api-key")

# Get all available tools
tools = adapter.tools()

# Use tools with a CrewAI agent
agent = Agent(
    role="automation_specialist",
    tools=tools,
)

Direct Tool Execution

from crewai_tools.adapters.zapier_adapter import ZapierActionsAdapter

adapter = ZapierActionsAdapter()
tools = adapter.tools()

# Find a specific tool by name
for tool in tools:
    if "gmail" in tool.name:
        result = tool._run(
            instructions="Send an email",
            to="user@example.com",
            subject="Hello from CrewAI",
        )
