All [custom fields](https://dev.wix.com/docs/rest/crm/members-contacts/members/custom-fields/custom-fields/introduction.md) are automatically suggested for members to add to their profiles when they are created. This API retrieves both custom fields and system fields available from the Wix Members Area. The list of suggested fields can be found in the dashboard after clicking the "Add More Fields" button in the "Member Account & Profile Info" section. See [Adding fields to member profiles](https://support.wix.com/en/article/site-members-customizing-your-member-profile-fields#adding-fields-to-member-profiles) for more information. ## Before you begin It’s important to note the following before starting to code: - A site must have the [Wix Members Area](https://www.wix.com/app-market/web-solution/members-area) installed from the App Market. ## Terminology - **Custom Field**: A user-defined field that extends the default member profile information. - **System Field**: A Wix-defined field from the default member profile information. @sdk_package_setup
