[UNITH](https://unith.ai) makes it possible to create engaging user experiences through the provision of Digital Humans. Our Digital Humans are designed to act swiftly, respond promptly, and above all, assist, guide, support, and engage your users effectively.

We aim to amplify your concepts with our technology, fostering a next-generation experience.

This documentation encompasses fundamental aspects such as **access, avatar creation, and response management**. Our API empowers you to programmatically generate Digital Humans, seamlessly integrating UNITH's cutting-edge AI capabilities into your product.  UNITH AI helps you think outside the bot.

# High Level Overview

The UNITH API is composed of the following components.

- **Authentication**
- **User**
- **Organisation**
- **Head**
- **Video**
- **Head Visuals**
- **Voices**
- **Document**

## Authentication

The component you use and the order in which you use them, largely depends on the type of user you are and your specific use case.

All users will need to use the Authentication endpoint to authenticate, and generate their Bearer token as described in [User](docId\:A6pxi9WVCN3uXnytWJ7JA).

## Head Creation

The first thing you will do is create your first digital human (referred to interchangeably as "head"). You do this as described 
in [Create a Digital Human](docId\:HobOROpyEM9TuenMqcf-S). You will already have all the dependencies associated with your organisations (most notably, faces (head\_visuals) and voices to choose from)

### Head Modification

All Digital Humans can be modified and often are. This is described in [Update a Digital Human](docId\:Gjy-Qc6AlW5TK6SsCxrpP). 

### Voices

Voices are essential to digital human configuration. Voices endpoints give you visibility into the voices you have available to you, when creating or modifying a Digital Human. See [List Voices](docId\:ujeQeSNYXa-j9j2_Z6jtL) to see voices available to your user. Check our guidelines on [TTS Providers Selection.](https://docs.unith.ai/voice-selection-guide-tts)

### Head Visuals

Head visuals are effectively the faces of your Digital Humans. You can use a single head visual for more than one Digital Human. See [List Faces](docId\:vpzbfsclK26XBCiLlNVDG) to see faces available to your user.

### Document

When using "document" based digital human, the document endpoint is required to load specific knowledge into the Digital Human. This is only required for doc\_qa use cases, as defined in [Create a Document Based Digital Human](docId:0D_QDu8Wz5ugUA-DEoseA).

# Bring your own Faces

UNITH allows you to easily create your own head visuals that you can use within your organization. 

## Video

The video endpoint is used to upload a short video of the person you wish to import into the platform. This video forms the basis of pre and post processing that occurs in creating your Head Visual.

## Head Visuals

Head visuals are effectively the face to your Digital Human. You can use a single head visual for more than 1 digital human. Head visuals can be both public or private. Private head visuals are available to only your organization, while public head visuals are available to others.

# A typical workflow

As an API user interesting in creating your first digital human, you will start by

1. Listing the faces (head visuals) you have available to you.
2. Selecting the most appropriate face for your use case
3. Creating a digital human
4. Accessing the digital human via chat.unith.ai as defined in [Interact with a Digital Human](docId\:HobOROpyEM9TuenMqcf-S)
5. Reviewing and modifying the digital human after your initial tests
6. (Optional) Embedding the digital human in your app as defined in [Embed Legacy Digital Humans in your Application](docId\:TDwdJ0Bo8et9F0k9o5Kvb) or [Embed using iframe](docId\:FCs2ALc_YoSeU88sfKnlL).
