| Webhook | Receives balance notifications from SePay/Casso |
| Code (idempotency) | Blocks duplicate webhooks to avoid recording payments twice |
| Sheets Lookup | Finds an order by its code in the transfer description |
| IF | Checks the amount and sends discrepancies to a person |
| Zalo/Email | Notifies you and the customer that payment for order #123 was received |
Installation prerequisites

Frequently asked questions
Is connecting my bank account safe?
SePay/Casso only reads balance changes through the bank's official channel and cannot transfer funds. The workflow only receives incoming-payment notifications.
What if a customer underpays or overpays?
Amount discrepancies go to a separate branch for human review. The system does not guess.
What is the refund policy?
Within 7 days of purchase, if the workflow does not work as described and our support team cannot fix it, you receive a 100% refund by bank transfer. See our refund policy.
