Setting Up Your Lowcode Environment
Most lowcode platforms provide intuitive onboarding. Here’s a sample setup using n8n:
- Sign up and log in to your chosen platform.
- Create a new workflow/project.
- Add a webhook node to receive incoming data.
1{
2 \"nodes\": [
3 {
4 \"parameters\": {
5 \"path\": \"ai-agent-webhook\"
6 },
7 \"name\": \"Webhook\",
8 \"type\": \"n8n-nodes-base.webhook\",
9 \"typeVersion\": 1
10 }
11 ]
12}
13
This webhook will handle incoming frontend requests for realtime AI interaction.
Connecting to OpenAI’s Realtime API
Now, connect your workflow to OpenAI’s realtime API. Authenticate using your API key and set up the streaming endpoint.
1const fetch = require('node-fetch');
2
3async function streamOpenAI(input) {
4 const response = await fetch(\"https://api.openai.com/v1/realtime/chat\", {
5 method: \"POST\",
6 headers: {
7 \"Authorization\": `Bearer ${process.env.OPENAI_API_KEY}`,
8 \"Content-Type\": \"application/json\"
9 },
10 body: JSON.stringify({
11 model: \"gpt-4\",
12 messages: [{ role: \"user\", content: input }],
13 stream: true
14 })
15 });
16 for await (const chunk of response.body) {
17 process.stdout.write(chunk);
18 }
19}
20
Insert your API key securely and handle the streaming chunks for real-time output.
Building Your First Realtime AI Agent
Let’s build a simple chatbot that responds instantly. Here’s a high-level workflow:
- User sends a message via a frontend UI (web or mobile)
- Message is posted to a webhook (n8n, Bubble, or Retool)
- The workflow triggers an OpenAI realtime API call
- The response streams back to the user interface
