Cannot add product to cloud zoo as an issuer


I’ve been trying to implementing a cloud zoo based license for a grasshopper plugin by following these guidelines.

I’m posting a sample code for adding products, which returns me a https 400 non-sucessful response with the following message:

{“Error”:“ErrorData”,“Description”:“The data received is badly formed or incomplete.”,
“Message”:“Cannot create an abstract class.”,
… other long error messages

Which is weird since i was trying to pass the same payload object as in the example. What am I doing wrong here? (1.9 KB)

The payload needs to be sent as JSON. Try this…

r =, json=payload, headers=header)
