# Integration API overview

> Vendschat Integration API for Zapier, Make, n8n, and custom HTTP — OpenAPI playground, base URL, and Growth+ plan gates.

Use the **Integration API** (`/v1/integrations/*`) to send messages, manage contacts and labels, and subscribe to outbound webhooks from Zapier, Make, n8n, or your own HTTP client.

> [!NOTE]
>
> **Base URL:** `https://api.vendschat.com/v1` · **Auth:** Bearer API key or `X-API-Key` · **Plan:** **Growth+** · Endpoint pages in this tab are generated from [`/openapi/integrations.json`](https://docs.vendschat.com/openapi/integrations.json).

## Quick start

**1. Create an API key**

On **Growth+**, open **Settings → Workspace → Integrations** → **Zapier**, **Make**, or **n8n**, then create a key. See [API keys](https://docs.vendschat.com/integrations/api-keys-and-rest-api.md).

**2. Authenticate**

Read [Authentication](https://docs.vendschat.com/api-reference/authentication.md), then open **GET /integrations/me** in the sidebar playground.

**3. Send or subscribe**

Use **POST /integrations/messages/send** or **POST /integrations/webhooks/subscribe**. Event payloads: [Webhooks guide](https://docs.vendschat.com/integrations/webhooks-guide.md).

## Plan gates

| Capability | Plan |
| - | - |
| Integration API keys + `/v1/integrations/*` | **Growth** or **Advanced** |
| Outbound webhooks | **Growth** or **Advanced** |
| In-app **REST API** settings menu | **Advanced** |
| Hosted n8n | **Advanced** |

## Notes

* Prefer **POST /integrations/messages/send** for custom HTTP. `send-form` / `send-from-form` are Zapier/Make platform helpers.
* Template variable keys come from **GET /integrations/messages/templates/{id}** (for example `body_1`).
* Co-Admin never sends customer messages — this API does.
