Problem statement/Symptoms
Receiving an error similar to the following:
Is it possible to increase the number of allowed callback urls?
Solution
Unfortunately, the 100 limit isn’t an entity limit and is configured on a per-environment basis . We do not now generally grant any increase above the current limit of 100 Allowed Callback URLs. Possible workaround might be to use wildcard subdomains , though this may not be a viable option in all cases.
