List things associated with a principal

To list the things associated with the specified principal, run the list-principal-things command. Note that this command doesn't list the attachment type between the thing and the certificate. To list the attachment type, use the list-principal-things-v2 command. For more information, see List things associated with a principal V2.

$ aws iot list-principal-things \
    --principal "arn:aws:iot:us-east-1:123456789012:cert/2e1eb273792174ec2b9bf4e9b37e6c6c692345499506002a35159767055278e8"

The output can look like the following.

{
    "things": [
        "MyLightBulb1",
        "MyLightBulb2"
    ]
}
