## 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](https://doc.wearepatchworks.com/product-documentation/developer-hub/connector-builder/building-your-own-connector/4-endpoints) and [authentication](https://doc.wearepatchworks.com/product-documentation/developer-hub/connector-builder/building-your-own-connector/3-authentication-methods/authentication-method-options) variables are needed for different things), techniques for adding and managing variables and parameters is always the same.
