Activepieces Integration

Activepieces is an open-source workflow automation platform with a user-friendly interface. It supports AI pieces (modules) for integrating language models into automation flows.

Activepieces' AI pieces support custom OpenAI-compatible endpoints.

Prerequisites

An LLM API account with an API key
Activepieces installed or accessible

Setup

Get Your LLM API Key

Log in to your LLM API dashboard
Click Create Key to Start
Copy your new API key immediately — it will only be shown once
Store the key securely (e.g., in a password manager or .env file)

LLM API is an OpenAI-compatible gateway that gives you access to dozens of AI models through a single API key and endpoint.

Configure LLM API in Activepieces

Open Activepieces and navigate to your flow.
Add an AI piece (e.g., "Ask AI" or "OpenAI").
Click "New Connection" for the AI piece.
Enter:
- API Key: paste the key you copied from app.llmapi.ai/api-keys
- Base URL: https://api.llmapi.ai/v1
Select the model and configure the prompt.
Save and run the flow.

Test the Integration

Verify that Activepieces can successfully communicate with LLM API by sending a test request. All requests will now be routed through LLM API.

Activepieces is open-source and self-hostable, giving you full control over your automation and AI pipeline.

Benefits of Using LLM API with Activepieces

Multi-Provider Access: Use models from OpenAI, Anthropic, Google, and more through a single API
Cost Control: Track and limit your AI spending with detailed usage analytics
Unified Billing: One account for all providers instead of managing multiple API keys
Caching: Reduce costs with response caching for repeated requests
