is it possble to pull a list of the space owners

I would like to know if there is any way for us to obtain a list of the space owners?

There is, but it isn't trivial unless you are familiar with the REST API.

I am going with the assumption that a Space "owner" is synonymous with a Person that has "manage" permission in the Space.

The pseudo code for doing this would look something like this...

For each of the 500 Spaces:

  Fetch the appliedEntitlements for the Space (may require paging through results)

  For each appliedEntitlement:

      If the appliedEntitlement is for a Person and the appliedEntitlement has "manage" permission

          Mark this Person as an Owner

      If the appliedEntitlement is for a Security Group and the appliedEntitlement has "manage" permission

          Fetch the Person(s) in the Security Group (may require paging through results)

          For each Person:

              Mark this Person as an Owner

    Send an email to the Owners

The API endpoints of interest to you are these:

Jive REST API v3.14 → Place service (Get Applied Entitlements)

Jive REST API v3.14 → SecurityGroup service (Get Members)
