!CHAPTER HTTP Interface for AQL User Functions Management

!SUBSECTION AQL User Functions Management

This is an introduction to ArangoDB's HTTP interface for managing AQL
user functions. AQL user functions are a means to extend the functionality
of ArangoDB's query language (AQL) with user-defined JavaScript code.
 
For an overview of how AQL user functions work, please refer to
[Extending Aql](../AqlExtending/README.md).

The HTTP interface provides an API for adding, deleting, and listing
previously registered AQL user functions.

All user functions managed through this interface will be stored in the 
system collection *_aqlfunctions*. Documents in this collection should not
be accessed directly, but only via the dedicated interfaces.
