What is Webhook authentication?

Webhook authentication is a security method used to verify that a webhook request comes from a trusted source. When one system (like Vtiger CRM) sends automated data to another system via a webhook, authentication ensures that the receiving system can validate the sender's identity.
This is typically done using:

• Basic Authentication (username and password)
• Bearer Tokens (secure access tokens)
• Custom Headers (to include secret keys or verification values)
