Parameter

Type

Description

destination

String

Target service type.

  • OBS: Notifications are sent to the OBS service.

  • SMN: Notifications are sent to the SMN service.

  • DIS: Notifications are sent to the DIS service.

  • FunctionGraph: Notifications are sent to FunctionGraph.

Enumeration values:

  • OBS

  • SMN

  • DIS
