# Create a repository link
<a name="repositorylinks-create"></a>

You can use the **create-repository-link** command in the AWS Command Line Interface (AWS CLI) to create a link between your connection and the external repository to sync to.

Before you can create a repository link, you must have already created your external repository with your third-party provider, such as GitHub.

**To create a repository link**

1. Open a terminal (Linux, macOS, or Unix) or command prompt (Windows). Use the AWS CLI to run the **create-repository-link** command. Specify the ARN of the associated connection, the owner ID, and the repository name.

   ```
   aws codeconnections create-repository-link --connection-arn  arn:aws:codeconnections:us-east-1:account_id:connection/001f5be2-a661-46a4-b96b-4d277cac8b6e --owner-id account_id --repository-name MyRepo 
   ```

1. This command returns the following output.

   ```
   {
       "RepositoryLinkInfo": {
           "ConnectionArn": "arn:aws:codeconnections:us-east-1:account_id:connection/aEXAMPLE-8aad-4d5d-8878-dfcab0bc441f",
           "OwnerId": "account_id",
           "ProviderType": "GitHub",
           "RepositoryLinkArn": "arn:aws:codeconnections:us-east-1:account_id:repository-link/be8f2017-b016-4a77-87b4-608054f70e77",
           "RepositoryLinkId": "be8f2017-b016-4a77-87b4-608054f70e77",
           "RepositoryName": "MyRepo",
           "Tags": []
       }
   }
   ```
