CreatePolicy
Creates a new managed policy for your AWS account.
This operation creates a policy version with a version identifier of v1
and sets v1 as the policy's default version. For more information about policy versions, see Versioning for managed policies in the IAM User Guide.
As a best practice, you can validate your IAM policies. To learn more, see Validating IAM policies in the IAM User Guide.
For more information about managed policies in general, see Managed policies and inline policies in the IAM User Guide.

Request Parameters
For information about the parameters that are common to all actions, see Common Parameters.
Description
A friendly description of the policy.
Typically used to store information about the permissions defined in the policy. For example, "Grants access to production DynamoDB tables."
The policy description is immutable. After a value is assigned, it cannot be changed.
Type: String
Length Constraints: Maximum length of 1000.
Required: No
Path
The path for the policy.
For more information about paths, see IAM identifiers in the IAM User Guide.
This parameter is optional. If it is not included, it defaults to a slash (/).
This parameter allows (through its regex pattern) a string of characters consisting of either a forward slash (/) by itself or a string that must begin and end with forward slashes. In addition, it can contain any ASCII character from the ! (\u0021
) through the DEL character (\u007F
), including most punctuation characters, digits, and upper and lowercased letters.
You cannot use an asterisk (*) in the path name.
Type: String
Length Constraints: Minimum length of 1. Maximum length of 512.
Pattern: ((/[A-Za-z0-9\.,\+@=_-]+)*)/
Required: No
PolicyDocument
The JSON policy document that you want to use as the content for the new policy.
You must provide policies in JSON format in IAM.
The maximum length of the policy document that you can pass in this operation, including whitespace, is listed below. To view the maximum character counts of a managed policy with no whitespaces, see IAM and AWS STS character quotas.
To learn more about JSON policy grammar, see Grammar of the IAM JSON policy language in the IAM User Guide.
The regex pattern used to validate this parameter is a string of characters consisting of the following:
- Any printable ASCII character ranging from the space character (
\u0020
) through the end of the ASCII character range - The printable characters in the Basic Latin and Latin-1 Supplement character set (through
\u00FF
) - The special characters tab (
\u0009
), line feed (\u000A
), and carriage return (\u000D
)
Type: String
Length Constraints: Minimum length of 1. Maximum length of 131072.
Pattern: [\u0009\u000A\u000D\u0020-\u00FF]+
Required: Yes
PolicyName
The friendly name of the policy.
IAM user, group, role, and policy names must be unique within the account. Names are not distinguished by case. For example, you cannot create resources named both "MyResource" and "myresource".
Type: String
Length Constraints: Minimum length of 1. Maximum length of 128.
Pattern: [\w+=,.@-]+
Required: Yes
