# Codeblock

ReplyCX provides **‘Codeblock’** action block, a powerful tool allowing custom functions to be quickly integrated into projects for optimized performance.

Some ways on how it can be used are:

* Fetching data from databases and rendering them dynamically as buttons, or carousels.
* Integrations with third-party systems.

### Setting up the codeblock:

1. Add the action block on the canvas by clicking on **'+'.**
