Here is the example of use AED currency in PayPal. You can use same for other currencies.

Follow this step to support other currencies in paypal:

1) Override Config.php and Nvp.php


<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <preference for="Magento\Paypal\Model\Config" type="{Vendor}\{Module}\Model\Magento\Paypal\Config" />
    <preference for="Magento\Paypal\Model\Api\Nvp" type="{Vendor}\{Module}\Model\Magento\Paypal\Api\Nvp" />

2) Add your currency in $_supportedCurrencyCodes


protected $_supportedCurrencyCodes = [
    'AED', // Add currency

3) Now convert currency amount to USD amount in API request


Inject \Magento\Directory\Helper\Data class for convert currency rate

Approx after line: 1175


if ($request["METHOD"] == "SetExpressCheckout" || $request["METHOD"] == "DoExpressCheckoutPayment")
    if($request['CURRENCYCODE'] == "AED") {

        $payAmt = $request['AMT'];
        $payShippingAmt = $request['SHIPPINGAMT'];
        $payItemAmt = $request['ITEMAMT'];
        $payTaxAmt = $request['TAXAMT'];
        $conAmt = round($this->_currencyHelper->currencyConvert($payAmt, "AED", "USD"), 2);
        $conShippingAmt = round($this->_currencyHelper->currencyConvert($payShippingAmt, "AED", "USD"), 2);
        $conItemAmt = round($this->_currencyHelper->currencyConvert($payItemAmt, "AED", "USD"), 2);
        $conTaxAmt = round($this->_currencyHelper->currencyConvert($payTaxAmt, "AED", "USD"), 2);

        //set converted USD amount to request api

        $request['CURRENCYCODE'] = "USD";
        $request['AMT'] = $conAmt;
        $request['SHIPPINGAMT'] = $conShippingAmt;
        $request['ITEMAMT'] = $conItemAmt;
        $request['TAXAMT'] = $conTaxAmt;

Note: set Transfer Cart Line Items to No From

Store->Configuration->Sales->PaymentMethod->Paypal->Configure->Advanced Settings

To pass only order, shipping and tax amount

If you set yes from this config setting. Magento passes all cart item amount to PayPal request and you have to change the logic of converting price.

  • In Magento2.2.4 EE I have edited above files and configured as defined by you. Now on checkout page at order placing time I am getting that message "PayPal gateway has rejected request. Receiving country does not support the transaction currency (#10605: Transaction refused because of an invalid argument. See additional error messages for details)." Please help me what can I do to resolve it. Merchant country = UAE and default currency = AED. May 27, 2019 at 5:23

I've created a simple M2 module to handle this. You can use it https://github.com/zamoroka/Magento-2-Paypal-All-Currencies-extension

  • Thanks, After I installed your extension, Paypal show up, But I have an issue "PayPal gateway has rejected request. Order total is invalid (#10401: Transaction refused because of an invalid argument. See additional error messages for details)." Do you know how to fix it? Oct 22, 2020 at 3:32
  • Hi @DavidDuong This module was developed 3 years ago just for fun. Unfortunately, I don't have time currently to maintain it but feel free to create an issue in github repo or even fix it, I'll review PR and approve it if there is a good fix :) Oct 23, 2020 at 5:58
  • I have fixed it. Thanks! Oct 23, 2020 at 8:26

My base currency is INR and PayPal currency set to USD. On purchasing INR as the base it's working but on switching the currency to USD from frontend currency switcher. Paypal rejects with an error message.Do you have any idea to solve this. My requirement is if the current active currency is USD no need to convert.
