# Techniques for working with variables & parameters

## Introduction

When building connectors with the connector builder, you need to add/update variables and parameters in most stages of the process. Whilst the purpose of these will vary (for example, [endpoint](/product-documentation/developer-hub/connector-builder/building-your-own-connector/4-endpoints.md) and [authentication](/product-documentation/developer-hub/connector-builder/building-your-own-connector/3-authentication-methods/authentication-method-options.md) variables are needed for different things), techniques for adding and managing variables and parameters is always the same.
