# Get one CoworkerPricePlanHistory

> Retrieve a single CoworkerPricePlanHistory record by its Id.

A **CoworkerPricePlanHistory** is an audit record of the different contracts (for different plans - Tariff entity) a customer has had. Each entry captures a plan change — recording the previous and new plan names, their values, and whether the change was an upgrade.

This entity is read-only and is created automatically by the system whenever a customer's plan changes.

## Authentication

  This endpoint requires OAuth2 authentication. Include a valid bearer token in the `Authorization` header.
  The authenticated user must be a full unrestricted administrator or have the **`CoworkerPricePlanHistory-Read`** role.
</Note>
