# 7. Secure Webhook Integration Framework

Each registered endpoint is provisioned a unique, HMAC-SHA512 hashed secret combined with its Telegram Chat ID or system UUID.

* **Key Derivation Function (KDF):** Generates per-session webhook tokens.
* **Replay Protection:** Implements nonce and timestamp validation to mitigate replay attacks.

#### 7.2 Encrypted Payload Transport

All webhook payloads are encapsulated within AES-256-GCM encrypted JSON packets, ensuring confidentiality and integrity.

#### 7.3 Integration Workflow

1. Robot subsystem triggers operational event.
2. Event payload transmitted via HTTPS POST webhook.
3. SIG validates signature, decrypts payload.
4. Payload routed to designated microservice.
5. Response payload encrypted and returned.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://dashpay.gitbook.io/roboflux-whitepaper/7.-secure-webhook-integration-framework.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
