Functions

Functions are the building blocks for developing an extension. They come handy for all server side customization. Sigma executes functions without additional infrastructure cost. External function calls can be done using rest APIs. You have to generate an API token to call functions outside Sigma. 
Sigma uses Deluge for building functions. Deluge script builder provides a drag-and-drop user interface which helps in creating functions quickly. Build anything from simple methods like sending an email notification to complex recursive functions using the editor. Click here to know more about writing functions in Deluge.
