What is a thingId?

Question

Hi,

I noticed that if I query the Thing registry through the Java SDK (describeThing() function), the return value, DescribeThingResponse, has a "thingId" property. I don't see this value when I examine the thing in the AWS console. What is its purpose?

Is it safe to ignore the thingId in my application and just use the thingName as the unique identifier?

Thanks,
Frank

Yes. The **thingName** is effectively the primary key in that the APIs use that as the input to identify the Thing. The **thingId** is only returned in the response. Although you can use it for searching if you have fleet indexing enabled.
