Problem statement/Symptoms
Receiving an error similar to the following:
Is it possible to increase the number of 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.
