We want to add metadata when creating a payment (https://developer.paypal.com/docs/api/payments/v1/) through Rest APIs. However, there is no object to add metadata like a JSON field. If we try to do it with a string, there is an option for custom metadata, but it only supports a limited number of characters (maximum characters: 127, it might be 256).
But we have mandatory data to add this:
metadatas = {
'coupon': coupon_code,
'user_id': UserID,
'product_id': product.id,
'package': package_name,
'coupon_discount': discount,
'currency_code': CurrencyCode,
'exchange_rate': ExchangeRate,
'currency_symbol': CurrencySymbol,
'converted_price': final_price,
'base_currency': base_currency_code,
'base_currency_symbol': base_currency_symbol,
'base_price': base_price,
'requirements': Requirements[:400],
}
