# CfnLinkPropsMixin

Creates a link between a source account and a sink that you have created in a monitoring account.

Before you create a link, you must create a sink in the monitoring account. The sink must have a sink policy that permits the source account to link to it. You can grant permission to source accounts by granting permission to an entire organization, an organizational unit, or to individual accounts.

For more information, see [CreateSink](https://docs.aws.amazon.com/OAM/latest/APIReference/API_CreateSink.html) and [PutSinkPolicy](https://docs.aws.amazon.com/OAM/latest/APIReference/API_PutSinkPolicy.html) .

Each monitoring account can be linked to as many as 100,000 source accounts.

Each source account can be linked to as many as five monitoring accounts.
