# Using service-linked roles for re:Post Private
<a name="using-service-linked-roles"></a>

AWS re:Post Private uses AWS Identity and Access Management (IAM) [service-linked roles](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_terms-and-concepts.html#iam-term-service-linked-role). A service-linked role is a unique type of IAM role that's linked directly to re:Post Private. Service-linked roles are predefined by re:Post Private and include all the permissions that the service requires to call other AWS services on your behalf.

A service-linked role makes setting up re:Post Private easier because you don’t have to manually add the necessary permissions. re:Post Private defines the permissions of its service-linked roles, and unless defined otherwise, only re:Post Private can assume its roles. The defined permissions include the trust policy and the permissions policy, and that permissions policy can't be attached to any other IAM entity.

For information about other services that support service-linked roles, see [AWS services that work with IAM](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_aws-services-that-work-with-iam.html) and look for the services that have **Yes** in the **Service-linked roles** column. Choose a **Yes** with a link to view the service-linked role documentation for that service.

## Creating a service-linked role for re:Post Private
<a name="create-slr"></a>

You don't need to manually create a service-linked role. When you create your first private re:Post in the AWS Management Console, the AWS CLI, or the AWS API, re:Post Private creates the service-linked role for you. 

**Important**  
This service-linked role can appear in your account if you completed an action in another service that uses the features supported by this role. Also, if you were using the re:Post Private service before December 1, 2023, when it began supporting service-linked roles, then re:Post Private created the `AWSServiceRoleForrePostPrivate` role in your account. To learn more, see [A new role appeared in my AWS account](https://docs.aws.amazon.com/IAM/latest/UserGuide/troubleshoot_roles.html#troubleshoot_roles_new-role-appeared).

If you delete this service-linked role, and then need to create it again, you can use the same process to recreate the role in your account. When you create your first private re:Post, re:Post Private creates the service-linked role for you again. 

In the AWS CLI or the AWS API, create a service-linked role with the `repostspace.amazonaws.com` service name. For more information, see [Creating a service-linked role](https://docs.aws.amazon.com/IAM/latest/UserGuide/using-service-linked-roles.html#create-service-linked-role) in the *IAM User Guide*. If you delete this service-linked role, you can use this same process to create the role again.

## Editing a service-linked role for re:Post Private
<a name="edit-slr"></a>

re:Post Private doesn't allow you to edit the `AWSServiceRoleForrePostPrivate` service-linked role. After you create a service-linked role, you can't change the name of the role because various entities might reference the role. However, you can edit the description of the role using IAM. For more information, see [Editing a service-linked role](https://docs.aws.amazon.com/IAM/latest/UserGuide/using-service-linked-roles.html#edit-service-linked-role) in the *IAM User Guide*.

## Deleting a service-linked role for re:Post Private
<a name="delete-slr"></a>

You can also use the IAM console, the AWS CLI, or the AWS API to manually delete the service-linked role.

**To manually delete the service-linked role using IAM**

Use the IAM console, the AWS CLI, or the AWS API to delete the AWSServiceRoleForrePostPrivate service-linked role. For more information, see [Deleting a service-linked role](https://docs.aws.amazon.com/IAM/latest/UserGuide/using-service-linked-roles.html#delete-service-linked-role) in the *IAM User Guide*.
