When the status of a payment changes, the client is notified of the payment's status.

The client must share a Callback URL with SentBiz in advance, and firewall access must be configured.

After SentBiz receives the response from the webhook, it will retry any requests where the result value is not SUCCESS.

• Retry Policy: 12 attempts at 10-minute intervals.

When the client receives the webhook, they should proceed with internal processing and respond using the parameters below.

The client's response policy for the result parameter is as follows:

• If result is SUCCESS: Webhook transmission and retries stop.
• If result is FAILED: Retries will occur, up to 12 times at 10-minute intervals.

The client must ensure that their internal system prevents duplicate processing for webhooks that have already been received or marked as SUCCESS.

For example, if the same payment_id webhook is received again after being processed as SUCCESS:

• Internal processing should be skipped.
• The client should respond as follows: {payment_id: [same payment_id], result: SUCCESS}
