Question

Do we need timeSeriesAcl:read to read timeseries subscriptions?

Hello, 

Is timeSeriesAcl:read acl required for data point subscription consumption? 

Although the client has timeSeriesSubscriptionsAcl:read. We recieve: CogniteAPIError: Missing capability to read Time series | code: 403. When calling: ‘client.time_series.subscriptions.iterate_data’.

Thanks

    ​@Marwen TALEB  timeSeriesAcl:READ is required in addition to timeSeriesSubscriptionsAcl:READ when consuming data point subscriptions.

    The required capabilities for creating and consuming subscriptions are:

    1. Subscription access (timeSeriesSubscriptionsAcl):

      • READ — to list subscriptions and retrieve updates

      • WRITE — to create, update, or delete subscriptions

    2. Time series access (one of the following):

      • timeSeriesAcl:READ scoped to all or to the relevant data set IDs containing your time series

      • Or, if using Data Modeling, the applicable dataModelsAcl:READ and dataModelInstancesAcl:READ permissions

    CDF checks that the client has read access to the target time series, not just subscription-level permissions.
