OpenAPI exposes a series of different subscription types.
The root service group contains an endpoint to remove subscriptions across various subscription services.
It is meant as a convenient way of deleting many subscriptions at once (either by context id alone or by a combination of context id and a user defined tag).
All subscriptions for a streaming session can be removed by making a DELETE request against the subscriptions endpoint:
The response is always a 202 Accepted, which means that the deletions will be done eventually.
See reference documentation for more details on this.
