HSNM Forum

Dear HSNM Support,

Have a good Day,

We just want to ask for support regarding our HSNM Connection via API V2. Still, we are using Version 1 due to an error when we are using API V2.

We are trying to make a connection and test with API V2 since we are using V1 till now
But every time we have an error.

Below is the Script and code error.




Error: {"error":"Error! Parameters error. The data parameter is not in json format"}

)
return response.text

return json.dumps({"warning": "", "error": "Generic error"})

If you have some sample API for V2 much appreciated if u can share with us. We are using Python.

Thanks,
