# Introduction

## Welcome

Here you can explore how to use voice workflow automations with our API.

## Authentication

All API requests require an API key passed via the `Authorization` header:

```
Authorization: Bearer ck_live_...
```

Generate API keys from **Settings → API Keys** in your [CallCow dashboard](https://www.callcow.ai/settings?tab=api-keys).

<Warning>
  API keys are only shown once at creation time. Copy and store your key securely — you won't be able to see it again.
</Warning>

## Rate Limits

API requests are rate-limited to **60 requests per minute** per organization. If you exceed the limit, you'll receive a `429` response with a `Retry-After` header indicating when you can retry.
