To help prevent multiple users from modifying a given Polaris object at the same time, there is a system of object locking in place as part of the Polaris API platform.
Some API calls will handle checking/setting of locks as part of normal processing. For example, if an API call is made to update a patron and that patron object is already locked by another user, the API will return the appropriate HTTP status (409) indicating the object is already locked.
There are also a set of API calls that a calling application can use to explicitly lock and unlock specific objects. There are four required parameters:
