IAM JSON policy elements: Sid
The Sid
(statement ID) is an optional identifier that you provide for the
policy statement. You can assign a Sid
value to each statement in a statement
array. In services that let you specify an ID
element, such as SQS and SNS, the
Sid
value is just a sub-ID of the policy document's ID. In IAM, the
Sid
value must be unique within a JSON policy.
"Sid": "1"
The Sid
element supports uppercase letters, lowercase letters, and numbers.
In IAM, the Sid
is not exposed in the IAM API. You can't retrieve a
particular statement based on this ID.
Some AWS services (for example, Amazon SQS or Amazon SNS) might require this element and have uniqueness requirements for it. For service-specific information about writing policies, refer to the documentation for the service you're working with.
