# Resend Webhook Notification

The webhook notification resend API is intended for specific and necessary use cases, such as retrieving missed notifications or ensuring data integrity. \
Misusing this API by excessively requesting resends may result in disruptions to your merchant account and impact our services.

If you need to resend a webhook notification for development and debugging purposes, it is recommended to use the webhook resend functionality on [webhook page](https://console.ccpayment.com/webhook/index).

{% tab title="Remarks" %}
As a security measure, we will sign the returned data (and according to this only { code: 10000 } should be signed, but it's signing all the returned body.). Additionally, it will return Appid, Sign, Timestamp  in the header of the response.  The signature method SHA-256 (appid+appSecret+Timestamp+body).

Please use the data with caution if the signature verification fails. It indicates that the data has been tampered with.
