# UpdateLink
<a name="API_UpdateLink"></a>

Use this operation to change what types of data are shared from a source account to its linked monitoring account sink. You can't change the sink or change the monitoring account with this operation.

When you update a link, you can optionally specify filters that specify which metric namespaces and which log groups are shared from the source account to the monitoring account.

To update the list of tags associated with the sink, use [TagResource](https://docs.aws.amazon.com/OAM/latest/APIReference/API_TagResource.html).
