If you create a payment request in AED and enable multi-currency, you will receive the exact amount you requested in AED (minus the standard payment processing fee). Meaning, no FX charge will be incurred.
Please note our standard processing fee: 2.6%+1 AED for payments received in AED, for payments received in any currency other than AED, or using an international card, an additional fee of 1.5% per transaction will apply.
