Webhook Authentication

Webhook authentication is the process of verifying the identity and legitimacy of webhook requests coming from the webhook service to the webhook receiver. It is a critical security measure to ensure that incoming webhooks are from trusted sources and to protect the receiver from unauthorized access or malicious actions.

Webhook authentication is essential for maintaining the confidentiality, integrity, and availability of webhook-enabled applications. Without proper authentication, webhook receivers are left vulnerable to potential data breaches, unauthorized actions, and manipulation by malicious actors. By implementing webhook authentication, applications can ensure that only authorized webhook requests are processed, thus protecting sensitive data and maintaining the integrity of the system.
