# Guides

Guides are task-first, how-to side documentation. [<mark style="color:red;">**API &**</mark>
\ <mark style="color:red;">**Command Reference**</mark>](https://developer.magtek.com/api-and-command-reference) is where you look up a specific command, notification, or data
\
object, Guides is where you learn how to accomplish something end to end —
\
accepting an EMV payment, migrating your keys to AES, getting L3 certified, or
\
working with contactless cards. Each guide is written once and applies across
\
the DynaFamily, pulling together concepts and procedures that used to live
\
inside individual product manuals, and links into the reference for the exact
\
command details.

{% hint style="success" %}
Applies to: DynaFamily (DynaFlex II PED, Go, SCR, DynaProx). The core concepts — DUKPT, KSN, MAC, TR-31 — apply to MagTek MMS SCRAs generally.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://developer.magtek.com/guides/guides.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.
