These days I am playing with pricebooks, I can list and delete but is getting hard to create it through the API.

since I prepare my  json to post to 

https://inventory.zoho.com/api/v1/pricebooks

the result is

{ "code": -1, "message": "The file to be imported is blank." }

since now I would to say we have no intention to download it as file. so it is possible to get away from this import file?

Thank in advance :)
