# CreatePullRequestApprovalRule
<a name="API_CreatePullRequestApprovalRule"></a>

Creates an approval rule for a pull request.

## Request Syntax
<a name="API_CreatePullRequestApprovalRule_RequestSyntax"></a>

```
{
   "approvalRuleContent": "string",
   "approvalRuleName": "string",
   "pullRequestId": "string"
}
```

## Request Parameters
<a name="API_CreatePullRequestApprovalRule_RequestParameters"></a>

For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md).

The request accepts the following data in JSON format.

 ** [approvalRuleContent](#API_CreatePullRequestApprovalRule_RequestSyntax) **   <a name="CodeCommit-CreatePullRequestApprovalRule-request-approvalRuleContent"></a>
The content of the approval rule, including the number of approvals needed and the structure of an approval pool defined for approvals, if any. For more information about approval pools, see the AWS CodeCommit User Guide.  
When you create the content of the approval rule, you can specify approvers in an approval pool in one of two ways:  
+  **CodeCommitApprovers**: This option only requires an AWS account and a resource. It can be used for both IAM users and federated access users whose name matches the provided resource name. This is a very powerful option that offers a great deal of flexibility. For example, if you specify the AWS account *123456789012* and *Mary\$1Major*, all of the following would be counted as approvals coming from that user:
  + An IAM user in the account (arn:aws:iam::*123456789012*:user/*Mary\$1Major*)
  + A federated user identified in IAM as Mary\$1Major (arn:aws:sts::*123456789012*:federated-user/*Mary\$1Major*)

  This option does not recognize an active session of someone assuming the role of CodeCommitReview with a role session name of *Mary\$1Major* (arn:aws:sts::*123456789012*:assumed-role/CodeCommitReview/*Mary\$1Major*) unless you include a wildcard (\$1Mary\$1Major).
+  **Fully qualified ARN**: This option allows you to specify the fully qualified Amazon Resource Name (ARN) of the IAM user or role. 
For more information about IAM ARNs, wildcards, and formats, see [IAM Identifiers](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_identifiers.html) in the *IAM User Guide*.
