FORTE ERROR (doDirectPayment): E: Email is invalid is an error only due to incorrect email address of donor; it's not a decline therefore transaction will be processed and credited into their bank account.


"FORTE ERROR (doDirectPayment): E: Authentication is invalid" please send email to  along with merchant ID and the error code

R03 - Unable to Locate Account : Account number entered did not correspond to an actual bank account so the Forte was not able to pull funds. Most likely there was an error in either the bank account or routing no. Please contact the donor to confirm the bank info


 If "Parent Transaction not found or in Settling State" error appears, it means that the parent transaction, (which can be $1 the transaction processed for recurring setup) has been voided or still in settling state. Due to this the upcoming transaction is also rejected. We suggest the customer to cancel all the remaining transactions and set-up a new recurring transaction.


Authentication Is Invalid - This error occurs due to incorrect Forte credentials.
