Testing ACH Payments

ACH Payments

Coinflow provides a mock bank that can be used to fully test integration in our sandbox environment (no actual bank interaction occurs). The mock provider will accept any account numbers, routing numbers, names and addresses. The following amounts will trigger the defined results.

Test Amounts

Amount	Type	Result
11.11	Total	Bank account setup will fail - the account/routing numbers are in the negative accounts table
0.01	Subtotal	Will not get picked up for batching - will stay pending
1.11	Subtotal	On system ACH update, will fail - the account/routing numbers are in the negative accounts table
