Error with updating torrent using API

[heroas]

Hello,
Im trying to use your provided API in order to update a torrent. However im recieving this error:
"Torrent with ID %!d(string=0) doesn't exist"

I am correctly passing the API token as well as the corresponding username. And the ID certainly exists.
Is there something im missing? If so, I apologize for the silly question :).
