# WLA modules

Starting from v0.19 WLA code base is divided into several modules. Now you can use only those modules which are necessary for your business case. The list of available modules:

* tech modules which are mandatory to use: core, authorization, api requests, wallets, transactions
* optional business modules:
  * QR code scanner
  * assets overview
  * payment requests and invoices
  * decentralized market
  * signing generic texts
  * centralizaed market (not available productively)
  * voting (not available productively)

Contact your CoreLedger manager if you need WLA code base to build your own app. Access to each module repository and WLA as app template built with this code base are provided according to your agreement with CL.

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://teos-docs.coreledger.net/white-label-mobile-app/admin-user-guide/wla-modules.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.
