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.
