device_id={UNIQUE_ID}&key={CUSTOMER_KEY}
I have tried following as many examples as I could find online, but there really wasn't a lot that was helpful for me. I'm using Python and have imported the msgpack and did this:
msgpack.packb([device_id:00000000-0000-0000-0000-000000000000,customer_key:0123456789abcdef])
But I get an error it's invalid syntax, with the colon indicated as the offending character. I wanted to out the msgpack code into a CURL and send it. But so far, I'm doing something wrong in how I define my key/values here.
