UserPolicy / Action / put



Adds or updates an inline policy document that is embedded in the specified IAM user.

An IAM user can also have a managed policy attached to it. To attach a managed policy to a user, use AttachUserPolicy. To create a new managed policy, use CreatePolicy. For information about policies, see Managed policies and inline policies in the IAM User Guide.

For information about the maximum number of inline policies that you can embed in a user, see IAM and STS quotas in the IAM User Guide.


Because policy documents can be large, you should use POST rather than GET when calling PutUserPolicy. For general information about using the Query API with IAM, see Making query requests in the IAM User Guide.
