# Using Enterprise Knowledge APIs

This page outlines how to authenticate and use the Enterprise Knowledge APIs.

## Authentication

Twilio supports HTTP Basic authentication. To authenticate, include the Basic Authentication header where the username:password pair is one of the following:

| Username    | Password       | Best practice                                                                                                                                            |
| ----------- | -------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------- |
| API Key     | API Key Secret | This is the recommended way to authenticate with the Twilio APIs. When a key is compromised or no longer used, revoke it to prevent unauthorized access. |
| Account SID | AuthToken      | Limit your use to local testing.                                                                                                                         |

## Add knowledge bases and sources

A **knowledge base** organizes knowledge sources into containers that can be semantically indexed and searched to provide contextual information for AI and retrieval use cases. For example, FAQs, warranty policy, or product information necessary for your business needs.

Each Twilio account can have multiple knowledge bases and each base can contain multiple sources such as documents, websites, or text content that can be used for context and information retrieval.

**Knowledge sources** represent unstructured or semi-structured data (web pages and raw text) that are processed into searchable chunks for information retrieval and AI workflows.

Create a new knowledge source from various data sources such as web content, files, or raw text. Knowledge resources are processed and indexed to enable semantic search and retrieval.

#### Best practices

Keep the following best practices in mind when working with knowledge bases and sources:

* **Access and optimize content**: Regularly evaluate your existing knowledge sources for accuracy, relevance, and coverage. Identify any gaps or outdated information that could hinder an AI or human agent's performance.
* **Simplify and structure content**: Ensure that your content is clear and concise. Use headings, bullet points, and metadata to make information straightforward to navigate for both agents and end users.
* **Prioritize high-impact content**: Focus on updating and maintaining content that is frequently accessed or critical to customer interactions. Consider using analytics to determine which knowledge entries are most valuable.
