Open MachinaOs at `http://localhost:3000` 2. Click **File > New Workflow** or press `Ctrl+N` 3. You'll see an empty canvas with a component palette on the left ## Step 2: Add a Webhook Trigger 1. In the component palette, expand **Utilities** 2. Drag **Webhook Trigger** onto the canvas 3. Click the node to select it, then click the **gear icon** to configure: ``` Path: hello Method: POST ``` Your webhook will be available at `http://localhost:3010/webhook/hello` ## Step 3: Add an AI Chat Model 1. Expand **AI Models** in the palette 2. Drag **OpenAI Chat Model** onto the canvas 3. Position it to the right of the Webhook Trigger 4. Connect them by dragging from the Webhook's output handle to the AI model's input handle ### Configure the AI Model Click the gear icon and set: ``` Model: gpt-5.5 Temperature: 0.7 ``` Pick any model the provider offers. OpenAI currently exposes GPT-5.5 / 5.4 / 5.2, GPT-4.1 / 4.1-mini / 4.1-nano, o3 / o4-mini, and GPT-4o / 4o-mini. You need an OpenAI API key. Click the **key icon** in the toolbar to add it. ## Step 4: Set the Prompt In the AI model's parameters, set the **Prompt**: ``` You are a friendly assistant. The user sent: {{webhookTrigger.body}} Respond with a helpful greeting. ``` The `{{webhookTrigger.body}}` syntax pulls data from the webhook's output. ## Step 5: Add a Webhook Response 1. Drag **Webhook Response** from Utilities 2. Connect the AI model's output to the Webhook Response input 3. Configure it: ``` Status Code: 200 Body: {{openaiChatModel.response}} Content Type: application/json ``` ## Step 6: Deploy and Test 1. Click the **Deploy** button (purple) in the toolbar 2. Your workflow is now listening for webhooks ### Test with curl ```bash theme={null} curl -X POST http://localhost:3010/webhook/hello \ -H "Content-Type: application/json" \ -d '{"message": "Hello from curl!"}' ``` You should receive an AI-generated response! ## Your First Workflow Your completed workflow looks like this: ``` [Webhook Trigger] --> [OpenAI Chat] --> [Webhook Response] ``` Congratulations! You've built your first MachinaOs workflow. ## What's Next? Build an AI agent with memory and tools Automate WhatsApp messages Explore every node category Deploy to production
