Only those TenantConfig’s that have been implemented on the Tenant can be fetched. Is there an API that exists where I can see all the TenantConfig options (the id field of each TenantConfig) and what that TenantConfig value will dictate on the tenant – basically I am interested in the id of each TenantConfig along with the master description of that TenantConfig.
Not that I know of.
TenantConfig is basically a generic configuration store that any API can use.
TenantConfig options are generally documented with the API or feature that uses them.
