CJ on Pinterest?

Was thinking about automating pinterest for CJ, any warnings? do I need to cloak?

Hi,
I'm new in affiliates and yesterday registred in Commission Junction.
Tried pin some pictures in Pinterest but do not understand which one link I need show. Fore one link showed some error bla bla bla. Putting other links, how I do know that they will work and I will get rewarded for sales?

Please help me to start earn some cash with CJ in Pinterest.

I'd strongly suggest using an alternate domain (cloaking). Pinterest has gone back and forth on their approach to affiliates and at one point was even rewriting merchant links with their own affiliate links. You'll get the greatest security if your pin don't automatically appear to be affiliate pins.
