**To return a list of service dependencies of the service that you specify**

The following ``list-service-dependencies`` example returns a list of service dependencies of the service that you specify. ::

    aws application-signals list-service-dependencies \
        --start-time 1732021200 \
        --end-time 1732107600 \
        --key-attributes Environment=api-gateway:prod, Name=PetAdoptionStatusUpdater,Type=Service

Output::
