# REST API Overview

> Server-to-server integration with the Pipeline Public REST API.

The Pipeline Public REST API lets backend systems read and write Pipeline data
over HTTPS. Use it for CRM sync, automated quote creation, scheduled exports,
and any integration where your code runs on a server (not inside a Pipeline
iframe).

**Base URL**

```
https://app.pipeline.software/api/v1/
```

All requests must be authenticated with an API key. See [Authentication](/developers/api/authentication).
