# No-Code Integrations

> Use PolarGrid with n8n, Zapier, Make, and other automation tools

# No-Code Integrations

PolarGrid's OpenAI-compatible API works with any automation tool that supports HTTP requests. This guide shows how to connect from no-code platforms.

## Authentication Setup

PolarGrid edge endpoints accept your `pg_*` API key directly — a single HTTP node is all you need.

### Make Inference Calls

Configure an HTTP Request node:

| Field      | Value                                                      |
| ---------- | ---------------------------------------------------------- |
| **Method** | POST                                                       |
| **URL**    | `https://api.yto-01.edge.polargrid.ai/v1/chat/completions` |
| **Header** | `Authorization: Bearer pg_your_api_key`                    |
| **Header** | `Content-Type: application/json`                           |
| **Body**   | See below                                                  |

```json theme={null}
{
  "model": "qwen-3.5-27b",
  "messages": [
    {"role": "user", "content": "Your prompt here"}
  ]
}
```

## n8n

In n8n, use a single **HTTP Request** node:

* **POST** to `https://api.yto-01.edge.polargrid.ai/v1/chat/completions`
* `Authorization: Bearer pg_your_api_key`
* `Content-Type: application/json`
* Body: the chat completion JSON above

Store the API key in n8n's credentials store rather than hardcoding it in the node.

## Zapier / Make / Other Tools

Any tool with HTTP request support can call PolarGrid edge endpoints in a single step:

1. **HTTP step**: POST to the edge URL with `Authorization: Bearer pg_*`

The key differences per platform:

* **Zapier**: Use a "Webhooks by Zapier" action (Custom Request)
* **Make (Integromat)**: Use an "HTTP — Make a request" module
* **Pipedream**: Use a Node.js or HTTP step

## Available Endpoints

All standard PolarGrid endpoints work from no-code tools:

| Endpoint                        | Use Case                                      |
| ------------------------------- | --------------------------------------------- |
| `POST /v1/chat/completions`     | Chat / text generation                        |
| `POST /v1/audio/transcriptions` | Speech-to-text (send audio file as form data) |
| `POST /v1/audio/speech`         | Text-to-speech (returns audio bytes)          |
| `GET /v1/models`                | List available models                         |

## Choosing a Region

Pick the region closest to your automation platform's servers:

| Region    | ID       | Best For                     |
| --------- | -------- | ---------------------------- |
| Toronto   | `yto-01` | US East, Eastern Canada      |
| Vancouver | `yvr-02` | US West, Western Canada      |
| Montreal  | `yul-01` | Northeast US, Eastern Canada |

Replace the region ID in the URL: `https://api.{region-id}.edge.polargrid.ai`
