# Viewing a replication group's details (ElastiCache API)
<a name="Replication.ViewDetails.API"></a>

You can view the details for a replication using the AWS CLI `DescribeReplicationGroups` operation. Use the following optional parameters to refine the listing. Omitting the parameters returns the details for up to 100 replication groups.

**Optional Parameters**
+ `ReplicationGroupId` – Use this parameter to list the details of a specific replication group. If the specified replication group has more than one node group, results are returned grouped by node group.
+ `MaxRecords` – Use this parameter to limit the number of replication groups listed. The value of `MaxRecords` cannot be less than 20 or greater than 100. The default is 100.

**Example**  
The following code list the details for up to 100 replication groups.  

```
