According to our  documents for 2.8: (https://access.redhat.com/documentation/en-us/red_hat_3scale_api_management/2.8/html/providing_apis_in_the_developer_portal/create-activedocs-spec#activedocs_auto_fill_of_api_keys) we support the auto-fill of the following keys:

• user_keys
• app_ids
• app_keys
• client_ids
• client_secrets

But, in 2.9 only the following are supported:

• user_keys
• app_ids
• app_keys

Please don't include client_ids and client_secrets in 2.9 docs

PD: In 2.8 docs client_secrets has a typo: client_sercrets
