I have three accounts in the Paypal sandbox: two business and one personal. All of my Paypal accounts have USD as default currency.
In the above code I was using EUR as a currency.
When I am carrying out transaction, if I am paying from my personal (buyer) account in EUR, then my buyer account is getting money deducted (equivalent amount of USD is getting subtracted from my buyer account). This is totally fine, there is no issue with that.
The problem is that no amount is getting added to my business or (seller) account.
I found a post on Stack Overflow that reads:
if the currencycode of the transaction and the seller account doesnt match, then money doesnt get aded to sellers account
I changed the euro to USD, (since my sandbox seller test account is in USD) and found out that, after converting it into USD, then my money is getting added to my seller account.
Is this a problem with the sandbox only, or does it apply to live paypal as well?
I have a site where buyers can pay in GBP, EUR, MYN, SGD, AUD.
If the transaction needs to be carried out in particular currency, that is the currency set as per the seller account, then there's no need to use different currencies.
Since the currencyCode which is passed in SetExpressCheckOut should match with the DoExpressCheckout, and as I have faced problem, currencyCode needs to be same as that of sandbox seller account, so even if buyers are selecting GBP, I have to send it to SetExpressCheckout as the currencyCode of the seller account.
