Hi,
I am using the v5 of the c# api, i'm having error like this one when changing a campaign payment mode to "Clicks":
Error : The error code is not in this version.\r\n ErrorDetails :\r\n ErrorFieldPath : operations[1].update.payment_mode
This campaign has a advertising channel type of Display, a bidding strategy of TargetCpa and an actual payment mode of Unknown
Thanks
Claude
