# How to Show Custom Form Fields with Branding

BoldSign supports displaying custom form fields to users when creating templates or documents with a brand that has custom fields configured. This article will guide you on how to display custom form fields using branding via the API.

To display the custom form fields, set `ShowSharedCustomFields` to `true` when updating branding via the API.

Below are a few code examples demonstrating how to display custom form fields using branding.

Replace `brandId` with the ID of the existing brand to be used for sending the document. Update `brandname`,`emailDisplayName` and `brandlogo` according to your brand's details. After executing the code, custom form fields will be displayed when a user creates templates or documents using the updated brand.
