Audit Service

The Audit Service is a pivotal component within navida pro ecosystem, designed to capture, manage, and rectify audit events generated by various services. This service plays a crucial role in maintaining transparency, accountability, and data integrity across the system. Not only does it log critical activities and interactions within the application, but it also offers a mechanism to address and rectify errors that might arise during the process.
