Transactions may be declined for several reasons, and common errors you may see include:
Declined
Do Not Honor
Insufficient Funds
Failure to Connect
Timeout
Insufficient Funds: This occurs when the account balance is too low to cover the transaction. Confirm with the client whether their bank has processed the charge.
If a transaction is declined, Instinct provides the reason in the Gravity Payments pop-up.
Some cards, such as CareCredit, require specific processing methods and cannot be treated as regular credit cards. Ensure these cards are processed through their designated systems to avoid errors.
If the payment appears to have failed due to insufficient funds but the client believes it was processed, ask them to verify the transaction status with their bank.
