# Authentication

> Authentication model for the Plyne API.

The Plyne API uses organization-scoped API keys.

```bash theme={null}
Authorization: Bearer plyne_...
```

Manage API keys from **Developer → API Keys** in the dashboard. Every request is scoped to the organization that owns the key.

## Headers

```bash theme={null}
Authorization: Bearer plyne_...
Content-Type: application/json
```

## Behavior

* Invalid or missing keys return `401`.
* Keys without access to a resource return `403`.
* Rate limits are applied per organization.
