#### [ CLI ]

**Amazon CLI**  
**Example 1: To create a thing record in the registry**  
The following `create-thing` example creates an entry for a device in the Amazon IoT thing registry.  

```
aws iot create-thing \
    --thing-name SampleIoTThing
```
Output:  

```
{
    "thingName": "SampleIoTThing",
    "thingArn": "arn:aws:iot:us-west-2: 123456789012:thing/SampleIoTThing",
    "thingId": " EXAMPLE1-90ab-cdef-fedc-ba987EXAMPLE "
}
```
**Example 2: To define a thing that is associated with a thing type**  
The following `create-thing` example create a thing that has the specified thing type and its attributes.  

```
aws iot create-thing \
    --thing-name "MyLightBulb" \
    --thing-type-name "LightBulb" \
    --attribute-payload "{"attributes": {"wattage":"75", "model":"123"}}"
```
Output:  

```
{
    "thingName": "MyLightBulb",
    "thingArn": "arn:aws:iot:us-west-2:123456789012:thing/MyLightBulb",
    "thingId": "40da2e73-c6af-406e-b415-15acae538797"
}
```
