# Common parameters

In API development, maintaining consistency across endpoints is critical. Apidog addresses this by offering the `Common Parameters` feature, which allows for the reuse of parameters with identical names and descriptions across different endpoints.

## Configure common parameters

To modify or set up your common parameters, follow these steps:

## Utilizing Common Parameters

When entering parameter names in an endpoint, you will be presented with pre-defined Common Parameters for selection. Choosing a Common Parameter will automatically populate its Description.
