# General

## Welcome to Casso Developer

There is where you can find all the documentation, tutorials, and resources for **programming your software integration** **with Casso.**

Casso was born with the DNA of **security, automation**, and **unlimited integration**. We consider integration as the core value of our product. Therefore, we have developed Casso as providing a variety of ways to connect with other software systems, serving many **different purposes**.

The first two methods are for **End-users**: businesses and individuals who used Casso software to serve their revenue and expenditure management needs, and now need to integrate **Casso** into other software systems that enterprises are also using.&#x20;

**The OAuth 2 method** is for **enterprise software developers** who want to integrate Casso to give users the option of **linking Casso accounts** into the software.

## Expected Plan

Besides the above 3 built-in methods, we are also working on implementing the 4th method, which is developing a set of integrated libraries similar to **Plaid for Vietnam,** provided to software developers as **source code libraries**.

This set of libraries will help these partners develop **the functionality of linking users' banks** into their software, in a secure and simple way. Users will not need to create an account with Casso, just link banks right on the **Developer's web and app**. And **Developers** do not need to worry about the security of user accounts and data.

We expect to launch officially in early 2022. *Please get in touch if you are interested in participating in our Beta Test program.*
