# CreateApprovalRuleTemplate
<a name="API_CreateApprovalRuleTemplate"></a>

Creates a template for approval rules that can then be associated with one or more repositories in your Amazon Web Services account. When you associate a template with a repository, Amazon CodeCommit creates an approval rule that matches the conditions of the template for all pull requests that meet the conditions of the template. For more information, see [AssociateApprovalRuleTemplateWithRepository](API_AssociateApprovalRuleTemplateWithRepository.md).

## Request Syntax

{
   "approvalRuleTemplateContent": "string",
   "approvalRuleTemplateDescription": "string",
   "approvalRuleTemplateName": "string"
}
```

## Request Parameters
<a name="API_CreateApprovalRuleTemplate_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.

 ** [approvalRuleTemplateContent](#API_CreateApprovalRuleTemplate_RequestSyntax) **   <a name="CodeCommit-CreateApprovalRuleTemplate-request-approvalRuleTemplateContent"></a>
The content of the approval rule that is created on pull requests in associated repositories. If you specify one or more destination references (branches), approval rules are created in an associated repository only if their destination references (branches) match those specified in the template.  
When you create the content of the approval rule template, you can specify approvers in an approval pool in one of two ways:  
+  **CodeCommitApprovers**: This option only requires an Amazon Web Services 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 Amazon Web Services account *123456789012* and *Mary\$1Major*, all of the following are 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.amazonaws.cn/IAM/latest/UserGuide/reference_identifiers.html) in the *IAM User Guide*.
