To modify built-in schedules for VMware vSphere client jobs using the SnapCenter Plug-in for VMware vSphere REST APIs, you must follow the prescribed sequence of REST API calls.

Built-in schedules are the schedules that are provided as part of the product; for example, the MySQL database dump schedule. You can modify the following schedules:
Schedule-DatabaseDump
Schedule-PurgeBackups
Schedule-AsupDataCollection
Schedule-ComputeStorageSaving
Schedule-PurgeJobs

For each REST API, add https://<server>:<port> at the front of the REST API to form a complete endpoint.
