Key Operations Supported by CTS

After you enable CTS, whenever an SMN API is called, the operation may be recorded in a log file, which is then dumped to a specified OBS bucket for storage based on time and data changes.

However, if someone calls the SMN API to cancel a subscription without login, CTS will not record the operation. For example, if a subscriber clicks the link in an email to cancel the subscription, the API for unsubscribing is called, but CTS does not record the operation.

Table 1 lists the SMN operations that will be recorded by CTS.
