{% hint style="warning" %}
Operations don't support foreign [currencies](https://sandbox-doc.gitbook.io/ottu-team-sandbox-doc/user-guide-proposal/configuration/currencies). If a customer pays using a different currency than the MID (e.g., MID is KWD but payment is in USD via Ottu's currency exchange), operations won't work. They only function when the payment currency matches the MID currency.
