NOTE: For testing purposes, eCheck.Net transactions under $100 will be accepted. To generate a decline, submit a Transaction over $100. A monthly limit of $5000 is also configured in the sandbox. If you exceed this amount, your eCheck Transactions will fail with a "This transaction has been declined." error message.
Test for Specific Responses and Errors
Cards
Create a Payment Method using the following postal codes to generate a declined Transaction.
* Postal Code = "46282" - This Transaction will be declined.
* Postal Code = "46205" - The Transaction will be declined because of an AVS mismatch. The address provided does not match the cardholder's billing address.
ACH
To generate a decline using an ACH bank account, submit a Transaction over $100.
Duplicate Payment Methods
Create two Payment Methods with the same name and email address to generate "A duplicate record with ID [auth.net id] already exists error" for the second Payment Method.
