Zapier Integration

Zapier is the most popular no-code workflow automation platform, connecting 6,000+ apps. Its AI features and actions let you add language model capabilities to any automated workflow (Zap).

Zapier supports custom API connections through its webhook and API actions, letting you connect LLM API.

Prerequisites

An LLM API account with an API key
Zapier 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.

Use LLM API in Zapier

Create or edit a Zap in Zapier.
Add a "Webhooks by Zapier" action (POST request).
Configure the webhook:
- URL: https://api.llmapi.ai/v1/chat/completions
- Headers: Authorization: Bearer your-llm-api-key-here, Content-Type: application/json
Set the request body with your model and messages in JSON format.
Test the step.
Continue building your Zap with the AI response.

Test the Integration

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

Zapier's webhook action gives you full control over LLM API requests within your automated workflows.

Benefits of Using LLM API with Zapier

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
