# UpdateAgreement
<a name="API_UpdateAgreement"></a>

Updates some of the parameters for an existing agreement. Provide the `AgreementId` and the `ServerId` for the agreement that you want to update, along with the new values for the parameters to update.

**Note**  
Specify *either* `BaseDirectory` or `CustomDirectories`, but not both. Specifying both causes the command to fail.  
If you update an agreement from using base directory to custom directories, the base directory is no longer used. Similarly, if you change from custom directories to a base directory, the custom directories are no longer used.

## Request Parameters
<a name="API_UpdateAgreement_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.

 ** [AccessRole](#API_UpdateAgreement_RequestSyntax) **   <a name="TransferFamily-UpdateAgreement-request-AccessRole"></a>
Connectors are used to send files using either the AS2 or SFTP protocol. For the access role, provide the Amazon Resource Name (ARN) of the AWS Identity and Access Management role to use.  
 **For AS2 connectors**   
With AS2, you can send files by calling `StartFileTransfer` and specifying the file paths in the request parameter, `SendFilePaths`. We use the file’s parent directory (for example, for `--send-file-paths /bucket/dir/file.txt`, parent directory is `/bucket/dir/`) to temporarily store a processed AS2 message file, store the MDN when we receive them from the partner, and write a final JSON file containing relevant metadata of the transmission. So, the `AccessRole` needs to provide read and write access to the parent directory of the file location used in the `StartFileTransfer` request. Additionally, you need to provide read and write access to the parent directory of the files that you intend to send with `StartFileTransfer`.  
If you are using Basic authentication for your AS2 connector, the access role requires the `secretsmanager:GetSecretValue` permission for the secret. If the secret is encrypted using a customer-managed key instead of the AWS managed key in Secrets Manager, then the role also needs the `kms:Decrypt` permission for that key.  
 **For SFTP connectors**   
Make sure that the access role provides read and write access to the parent directory of the file location that's used in the `StartFileTransfer` request. Additionally, make sure that the role provides `secretsmanager:GetSecretValue` permission to AWS Secrets Manager.
