# SCRA DynaFamily Programmer's Manual

The SCRA DynaFamily Programmer's Manual is the complete reference for the Multi-Interface Card Reader Platform (MMS) command set. It's written once for the whole family — DynaFlex, DynaProx, and DynaFlex II Go share the same commands, responses, and notifications — so this manual is device-agnostic. To confirm which commands a specific reader supports, use the DynaFamily Command Matrix.

New to the platform? Start with [<mark style="color:red;">**About The SCRA DynaFamily Programmer's Manual**</mark> ](/api-and-command-reference/scra-dynafamily-programmers-manual.md)for scope and conventions, and [<mark style="color:red;">**About Terminology**</mark>](/api-and-command-reference/scra-dynafamily-programmers-manual/about-terminology.md) for the vocabulary used throughout.

# 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/api-and-command-reference/scra-dynafamily-programmers-manual.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.
