Hi Bill, maybe I can help.
In general, you can follow this: http://docs.exosite.com/tutorials/device-api-with-curl/
Here are a few more details:
You need to create a Product Solution and then use the the product end point.
If you don’t have a product already, create one.
You can find your Product URL endpoint by clicking here, it will copy to your clipboard.
It should look like: https://l4pizzkfjnzz4wogc.m2.exosite.io
You don’t need to create a new device if you have the auto register identity on.
Your activation call would look like this using the example product endpoint I sent you:
POST /provision/activate HTTP/1.1
Content-Type: application/x-www-form-urlencoded; charset=utf-8
Also make sure you have one or more resources to write to and read from:
Hope this helps!
