# Overview

> Manage custom fields that extend the sponsor data model

Custom fields extend the standard sponsor data model with your own properties — common uses include sponsorship tier, booth number, or contract details. Use these endpoints to create, update, and delete sponsor-level custom field definitions. Once defined, custom field values can be set when creating or updating sponsors.
