# Authentication

> Authenticate REST API requests with an API key.

The Postbase REST API is authenticated with an **API key**. Generate one under
**Developers** in the app, then send it as a bearer token.

## Base URL

```
https://www.postbase.so/api/v1
```

## Authorization header

```bash theme={null}
curl https://www.postbase.so/api/v1/channels \
  -H "Authorization: Bearer pb_live_…"
```

Every request must include `Authorization: Bearer <your key>`. Requests without
a valid key return `401 Unauthorized`. A key is scoped to the workspace it was
created in.

<Warning>
  Keys are shown once at creation. Store yours securely; rotate or revoke it
  from **Developers** if it leaks.
</Warning>
