# Use `ListFHIRDatastores` with an AWS SDK or CLI
<a name="healthlake_example_healthlake_ListFHIRDatastores_section"></a>

The following code examples show how to use `ListFHIRDatastores`.

------
#### [ CLI ]

**AWS CLI**  
**To list FHIR data stores**  
The following `list-fhir-datastores` example shows to how to use the command and how users can filter results based on data store status in AWS HealthLake.  

```
aws healthlake list-fhir-datastores \
    --filter DatastoreStatus=ACTIVE
```
Output:  

```
{
    "DatastorePropertiesList": [
    {
        "PreloadDataConfig": {
            "PreloadDataType": "SYNTHEA"
        },
        "SseConfiguration": {
            "KmsEncryptionConfig": {
                "CmkType": "CUSTOMER_MANAGED_KMS_KEY",
                "KmsKeyId": "arn:aws:kms:us-east-1:123456789012:key/a1b2c3d4-5678-90ab-cdef-EXAMPLE11111"
            }
        },
        "DatastoreName": "Demo",
        "DatastoreArn": "arn:aws:healthlake:us-east-1:<AWS Account ID>:datastore/<Data store ID>",
        "DatastoreEndpoint": "https://healthlake.us-east-1.amazonaws.com/datastore/<Data store ID>/r4/",
        "DatastoreStatus": "ACTIVE",
        "DatastoreTypeVersion": "R4",
        "CreatedAt": 1603761064.881,
        "DatastoreId": "<Data store ID>",
        "IdentityProviderConfiguration": {
            "AuthorizationStrategy": "AWS_AUTH",
            "FineGrainedAuthorizationEnabled": false
        }
    }
    ]
}
```
