Sorry if this has been posted before, but I have linked my Google Adsense to my account and the amounts are shown in the header. The currency is set as USD when actually all of my currencies are in GBP. Again, sorry if this has been pointed out before, just thought I would let you all know.
I'm afraid this is not possible, it's even in the help section for adsense: http://support.google.com/adsense/bin/answer.py?hl=en&answer=139783
Is it showing the right amount if it was converted to US Dollars, or is it showing the number as GBP with a $ on it?
Okay, just so I'm clear and know where to start looking in the API stuff, let's say you had £100.00 in your AdSense account, on here it shows $100.00?
I think it got it squared away now... I couldn't find a list of all supported currencies in AdSense, but it should show the proper symbol for CNY, EUR, GBP, INR and THB now... Everything else just defaults to $ for now. Let me know if it's not working for you (my AdSense account is USD, so couldn't really *truly* test it... it's just theory).
