Transactions can fail due to various reasons. It could be a payment gateway downtime, it could be due to incorrect account information like bank names, branch codes and also using Neo-banks(Opay, Kuda, Microfinance banks, etc) which might have transaction limits.
When making a payout, ensure you have selected the correct bank name and use more of commercial banks as much as possible.
If a payment fails more than once, reach out to the finance team via [email protected] or the support team.
You can also request for a refund of the transaction so you can retry it or request for the transaction to be reprocessed.
