Paypal 10418 error

I am getting an error while doing express checkout for australian currency in PayPal. (The currencies of the shopping cart amounts must be the same) My code works fine with US dollars.

I set the currency code "AUD" correctly in both setexpresscheckout and doexpresscheckout process, but I am 开发者_开发问答still getting an error.

What can I do to solve this?

You're obviously not sending the same currency in both SetExpressCheckout and DoExpressCheckoutPayment.
USD is the 'main' currency. This means that if no currency is specified, it falls back on USD by default. Which is why if you don't specify anything, it works properly.

Review (or post) your code for both SetExpressCheckout and DoExpressCheckoutPayment, as I'm sure you're not properly specifying CURRENCYCODE for either of the API calls.

I get same error code in soap message (10418) and get usefull description (The currencies of the shopping cart amounts must be the same.) in same soap message. I call setExpressCheckout with EUR currency, but I adjusted in my test account US country. My mistake occured this problem.

So it is always usefull check test/normal account adjustment!

I had this error and it was because the PaymentDetailType was not completed correctly. Make sure both ItemTotal and OrderTotal have a BasicAmountType entered.
