Project creation via Groupshare Rest API

Hello,

as we are trying to automate some project creation , I'm trying to use the API provided for it.

I'm currently trying to use the Post call both via swagger ui and via my own code

in both case I receive and status code in return as Created and a new ProjectID.

But If i try to upload file, get the project info back , ... it always return the message that the project doesn't exist

If I try to recreate the exact same project (same name) the I receive a Bad request message with the message saying that a similar project already exist. 

Any idea ?

thanks for your help
