Open a transaction
The REST API of SPS manages the changes of the configuration in transaction. You can open a transaction with a POST request, but the first change of the configuration will open the transaction automatically. For details about the transaction model of SPS see How to configure SPS using REST.

Note that this session ID refers to the connection between the REST client and the SPS REST API. It is not related to the sessions that SPS records (and which also have a session ID, but in a different format). |
