Amounts in Hungarian Forints (HUF)<\/h3>\n

In case of a transaction in HUF, PayPal expects the transaction amount and the line item amounts to be rounded to the nearest whole amount. For example, an amount of HUF 74499 must be rounded to HUF 74500. PayPal also expects the rounded line item amounts to add up to the rounded transaction amount. <\/p>\n

If you do not round the amounts, Adyen will do that. However, a discrepancy can occur between the transaction amount and the total of the line item amounts. When this happens, PayPal doesn't accept the transaction. To avoid that problem, we recommend that you round all HUF amounts yourself and check that they add up.<\/p>\n

PayPal risk fields<\/h3>\n

PayPal requires marketplaces<\/em> and also merchants in specific verticals<\/em> to send information about the context of the transaction, for risk mitigation purposes.<\/p>\n

Not all businesses need to send risk fields. Contact your PayPal account manager to verify.<\/div><\/div><\/p>\n

Common PayPal risk fields for marketplaces<\/h4>\n

As an example, the following table shows the most common paypalRisk<\/code> fields that marketplaces need to send. It is possible that PayPal requires you to send more, less, or other fields.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
