# Einstein Recommendations API

The Einstein Recommendations engine empowers marketers to deliver millions of messages across key digital channels that are personalized for each individual’s needs, interests, and preferences.

Developers use the Einstein Recommendations API to update the data used to provide recommendations, manage consumer privacy requests, and to easily download large reports.

## Set Up Your Development Environment

1.  In the Marketing Cloud Engagement web interface, go to **Einstein > Email or Web Recommendations > Reporting > Admin Tools > Manage API Keys**.

2.  Copy the **Crimson Kraken** API key value. This key is created when your account is provisioned.

3.  To authenticate your calls, pass the API key in the header like this:

    ```
    Host: https://app.igodigital.com
    POST /api/v2/organization/{customer_mid}/...
    Content-Type: application/json
    Authorization: Bearer YOUR_API_KEY
    ```
