# CreateServiceNetworkServiceAssociation
<a name="API_CreateServiceNetworkServiceAssociation"></a>

Associates the specified service with the specified service network. For more information, see [Manage service associations](https://docs.aws.amazon.com/vpc-lattice/latest/ug/service-network-associations.html#service-network-service-associations) in the *Amazon VPC Lattice User Guide*.

You can't use this operation if the service and service network are already associated or if there is a disassociation or deletion in progress. If the association fails, you can retry the operation by deleting the association and recreating it.

You cannot associate a service and service network that are shared with a caller. The caller must own either the service or the service network.

As a result of this operation, the association is created in the service network account and the association owner account.
