# API Authentication

All requests to the API endpoint must be authenticated with the workspace API key. Please note that API keys are unique to each workspace.

### How to get your workspace API key:

1. Log in to your account.
2. Select the workspace.
3. Go to settings, and select API Key.

From here you can create an API Key, or regenerate a new key. Once a new key is generated, the previous API key is made invalid.

> To authenticate any of your request, attach the API key in the request header as X-API-KEY

That's all, every request should work fine now.
