<p>Attaches tags to a secret. Tags consist of a key name and a value. Tags are part of the secret's metadata. They are not associated with specific versions of the secret. This operation appends tags to the existing list of tags.</p> <p>The following restrictions apply to tags:</p> <ul> <li> <p>Maximum number of tags per secret: 50</p> </li> <li> <p>Maximum key length: 127 Unicode characters in UTF-8</p> </li> <li> <p>Maximum value length: 255 Unicode characters in UTF-8</p> </li> <li> <p>Tag keys and values are case sensitive.</p> </li> <li> <p>Do not use the <code>aws:</code> prefix in your tag names or values because Amazon Web Services reserves it for Amazon Web Services use. You can't edit or delete tag names or values with this prefix. Tags with this prefix do not count against your tags per secret limit.</p> </li> <li> <p>If you use your tagging schema across multiple services and resources, other services might have restrictions on allowed characters. Generally allowed characters: letters, spaces, and numbers representable in UTF-8, plus the following special characters: + - = . _ : / @.</p> </li> </ul> <important> <p>If you use tags as part of your security strategy, then adding or removing a tag can change permissions. If successfully completing this operation would result in you losing your permissions for this secret, then the operation is blocked and returns an Access Denied error.</p> </important> <p>Secrets Manager generates a CloudTrail log entry when you call this action. Do not include sensitive information in request parameters because it might be logged.
