# Partner attribution

> Attribute Prequel workloads to your vendor partnerships

<Note>
  **Availability**

  Partner attribution is available on self-hosted and private cloud hosted Prequel packages only. Contact the Prequel team for more information.
</Note>

## Overview

Prequel works closely with vendor partners to ensure you can easily satisfy your partner relationships, including partner attribution on the workloads Prequel runs. When enabled, Prequel identifies itself with a partner-specific identifier on every connection it opens to a supported vendor. The queries and API calls Prequel makes on your behalf are then attributed to your partnership, including transfers to destinations owned by your customers.

## Supported partners

| Partner                                     | How it is sent                               | Identifier                               |

| Snowflake                                   | `application` connection parameter           | `{partner}_Prequel`                      |
| Databricks                                  | `User-Agent` entry on the SQL driver         | `prequel+{partner}/2024.1`               |

For self-hosted deployments, set the `collie.host_name_for_partner` value in your helm chart to your partner identifier. Prequel formats it according to each vendor's requirements. For private cloud deployments, contact the Prequel team to have your deployment configured and verified for partner attribution.

If you have questions about partner attribution, or would like support for a partner program not listed here, contact the Prequel team.
