# Authentication

> This guide covers how to use specific headers for authentication and authorization.

## Base URL

```json Base URL theme={null}
https://api.rolodexcrm.com/user-api/v1/
```

## Headers

These are included in all requests.

```json Content-Type theme={null}
application/json
```

```json API Key theme={null}
x-rolodex-api-key: f1e2d3c4b5a697...
```

The `x-rolodex-api-key` header should contain the user’s API key. This key is used for identifying the user and further processing the request. To use it, include the `x-rolodex-api-key` header with the value being your personal API key in your API requests.

## Where to find and create API Keys?

You can generate and manage your API Keys on the API page in settings. For each integration or build you generate a unique value key.

<Info>
  The API Key value genereated will look like this: `f1e2d3c4b5a697...`

You can mange and delete these keys from the same page.
