# Get API key

To interact with secured endpoints of the [Model Monitoring API](/cloud/reference/api/model_monitoring/dmm-api) or [Domino Platform API](/cloud/reference/api/domino-open-api), you must send an API authentication token or key along with your request. This parameter identifies you as a specific Domino user so Domino can check for authorization.

## Find your Domino Rest API key

<Warning>
  This feature will be deprecated in future versions of Domino. Domino recommends using [Service Accounts](/cloud/admin/identity-and-access/manage-users/service-accounts) as they provide stable, token-based authentication for API calls, independent access management, and stronger security.
</Warning>

To authenticate your requests, include your API key with the header `X-Domino-Api-Key`.

**Get your API key**

1. Go to **Account** > **Account Settings**.

<Warning>
  Anyone with this key can authenticate to the Domino application as the user it represents and take any actions that the user is authorized to perform. Treat it like a sensitive password.
