## Introduction
📄️ Webhook
Webhook notifications allow you to receive real-time updates about payment transaction status changes. When a payment's status changes (e.g., from pending to authorised, or from authorised to waiting), Hello Clever will send a POST request to your specified webhook endpoint.
📄️ HTTP Signature
When receiving webhooks, it's important to verify that the payload is sent by a trusted source and has not been tampered with. This is commonly achieved by using an HTTP signature, where the sender signs the payload using a secret key and a hashing algorithm (e.g., SHA256). The receiver can then verify the signature using the same secret key.
