# TAXII 2.1 Server Overview (App Version 1.0)

## Overview

The ThreatConnect® TAXII™ 2.1 server, which operates via a ThreatConnect [Service App](/v1/docs/playbook-services), can be used by an external TAXII client to retrieve data from your Organization and any Communities or Sources to which you have access. To connect to the ThreatConnect TAXII 2.1 server, the external TAXII client will require login credentials (username and password), which are configured by [creating a TAXII user](/v1/docs/creating-a-taxii-user-for-the-taxii-21-server).

The ThreatConnect TAXII 2.1 server supports Status, Collections, Manifest, and Objects requests. The latest version of TAXII 2.1 documentation is available at [https://oasis-open.github.io/cti-documentation/resources.html#taxii-21-specification](https://oasis-open.github.io/cti-documentation/resources.html#taxii-21-specification).
