1. IBM API Connect v10.x Documentation
"Using Spaces in Catalogs": "When Spaces are enabled in a Catalog
API provider teams can manage their APIs and Products in a dedicated Space... allowing each team to manage its own API consumers... When an application developer signs in to the Developer Portal
they select which Space to work in. The application developer can register applications only in the Spaces that they have access to
and can subscribe only to the Products that are available in those Spaces." This confirms that consumers
applications
and subscriptions are space-specific.
2. IBM API Connect v10.x Documentation
"Viewing the analytics for a Space": "Analytics data is specific to a Catalog
and is partitioned by Space. You can view the analytics data for a specific Space." This confirms that analytics are also partitioned by Space.
3. IBM API Connect v10.x Documentation
"Managing consumer access to Spaces": "When Spaces are enabled
the Developer Portal is partitioned by Space. Application developers who are members of a consumer organization can be granted access to one or more Spaces." This directly links consumer management to the Space level.
