Increase Allowed Callback URLs Entity Limit

Sep 10, 2025

Overview

When trying to add to a list of Allowed Callback URLs for an application, the following error is returned:

Error! Too many URIs defined (n), maximum 100 on property callbacks.

Applies To

Allowed Callback URLs

Cause

The Allowed Callback URL entity limit is fixed to 100 for performance reasons and generally cannot be increased or removed.

Solution

Use Organizations to set dynamic callback URLs for an application as a workaround. This will allow for using {organization_name} as a placeholder to dynamically specify a registered organization’s name in a URL (https://{organization_name}.exampleco.com). URLs with the {organization_name} placeholder should only be used on domains that are fully controlled (for example, https://{organization_name}.exampleco.com where the exampleco.com domain is controlled.
