Error code

transaction_requires_currency_code_for_custom_discount

Error message

Cannot create transaction without currency code

Common causes

• The transaction has a custom discount of type flat or per_seat, which needs a currency_code to know the discount's currency.

Troubleshooting

• Include a currency_code in the transaction payload.
• Change the discount type to percentage, which doesn't need a currency code.
