Answer 1

The data in ${resp.json()} is a list, so you should be able to directly iterate over the items in the list. Notice in the following example that @ is used in the :FOR statement, and that ${item} is a dictionary rather than an index:

:FOR   ${item}   in  @{resp.json()}
\   Log  ${item}
\   ${get_policy_id}=  Set variable    ${item['id']}
\   ${policy_name}=    Set variable    ${item['name']}
\   Log    ${policy_id},${policy_name}
