Checkout page language issue

[marcopassarelli]

I am trying to integrate with the PayPal Rest API and I have a problem when trying to create the checkout urls. I have tried with various locales but it doesn't always work. Accepted values are "it-IT", "en-GB", "da-DK", "ja-JP", but for example I cannot use "ru-RU" and "el-GR". Could someone help me?

Here  an example of the request to https://api-m.sandbox.paypal.com/v2/checkout/orders

{

    "intent": "CAPTURE",

    "purchase_units": [

        {

            "custom_id": "TRANSACTION_ID",

            "amount": {

                "currency_code": "EUR",

                "value": "1.00"

            }

        }

    ],

    "payment_source": {

        "paypal": {

            "experience_context": {

                "shipping_preference": "NO_SHIPPING",

                "payment_method_preference": "IMMEDIATE_PAYMENT_REQUIRED",

                "brand_name": "MY_BRAND",

                "locale": "el-GR",

                "landing_page": "GUEST_CHECKOUT",

                "cancel_url": "http://localhost:4200/cancel.html?brandName=MY_BRAND",

                "return_url": "http://localhost:4200/success.html?brandName=MY_BRAND"

            }

        }

    }

}
