You can use "transaction wrapper", which will allow you to store all the 
updates to user locally, but send the UPDATE request to your webservice 
later at transaction commit time. You may need to create custom 
transaction and enlist it with Keycloak TransactionManager.

This is what we have for LDAP federation provider right now. See 
TxAwareLDAPUserModelDelegate.
