Disabling Background Polling
BMC Helix Digital Workplace Catalog can perform calls to endpoints such as com.bmc.dsm.catalog:findActivities or com.bmc.dsm.catalog:findActivityLogs on a schedule, either as a primary way of updating its data (when callbacks are not possible, for instance) or as a safety net for situations where other mechanisms like callbacks would fail. This behavior is generally called "background polling".
Remote connectors are allowed to decline background polling by declaring the following capability:
If declared, BMC Helix Digital Workplace Catalog will stop performing background polling on all its connection instances.
Of course, this means you will have to rely on mechanisms like workflow callbacks to ensure BMC Helix Digital Workplace Catalog refreshes its version of data such as external activity details.
