    }
  ]
}

Common Error Scenarios

Invalid routing number

Error: 400 Bad RequestSolution: Verify the routing number is a valid 9-digit ABA routing number. The test environment requires real routing numbers.

Invalid account type

Error: 400 Bad RequestSolution: Ensure accountType is either “checking” or “savings” (lowercase).

Missing required fields

Error: 400 Bad RequestSolution: Verify all required fields are present: paymentType, merchantId, StandardEntryClassCode, bank object, and transaction object.

Payment processing failed

Error: 422 Unprocessable EntitySolution: The payment was rejected by the bank. Common reasons include insufficient funds, closed account, or invalid account information.

Important Notes

Real Routing Numbers Required: Even in the test environment, you must use valid bank routing numbers. Invalid routing numbers will be rejected.

Settlement Time: ACH payments take 3-5 business days to settle. The payment will appear as “pending” during this time.

Idempotency: Use the optional requestId field with a UUID to prevent duplicate payments if your request is accidentally submitted multiple times.

Best Practices

Validate Bank Information: Verify routing and account numbers before submitting to reduce failed payments
Store Payment IDs: Save the returned payment ID for status checking and reconciliation
Handle Async Nature: ACH is asynchronous - implement webhooks or polling to track payment status
Collect Customer Consent: Ensure you have proper authorization to debit the customer’s account
Use miscData Field: Store additional context like customer email, IP addresses for fraud prevention and customer support
