# 1. Setting up Portkey

Portkey allows you to use 250+ LLMs with your LiveKit agents, with minimal configuration required. Let's set up the core components in Portkey that you'll need for integration.

<Steps>
  <Step title="Create Virtual Key">
    Virtual Keys are Portkey's secure way to manage your LLM provider API keys. For LiveKit integration, you'll need to create a virtual key for OpenAI (or any other LLM provider you prefer).

    To create a virtual key:

    1. Go to [Virtual Keys](https://app.portkey.ai/virtual-keys) in the Portkey App
    2. Click "Add Virtual Key" and select OpenAI as the provider
    3. Add your OpenAI API key
    4. Save and copy the virtual key ID

      <img src="https://mintcdn.com/portkey-docs-add-third-party-integration-issues-fixes/iw8u5vDH8VX-5kWU/images/integrations/openai/virtual-key-2.png?fit=max&auto=format&n=iw8u5vDH8VX-5kWU&q=85&s=a8c33fd72639726334d697df5a9b5701" width="500" data-path="images/integrations/openai/virtual-key-2.png" />
    </Frame>

    <Note>
      Save your virtual key ID - you'll need it for the next step.
    </Note>
  </Step>

  <Step title="Create Default Config">
    Configs in Portkey define how your requests are routed and can enable features like fallbacks, caching, and more.

    To create your config:

    1. Go to [Configs](https://app.portkey.ai/configs) in Portkey dashboard
    2. Create new config with:
       ```json theme={null}
       {
           "virtual_key": "YOUR_VIRTUAL_KEY_FROM_STEP1"
       }
       ```
    3. Save and note the Config ID for the next step

    <Frame>
      <img src="https://mintcdn.com/portkey-docs-add-third-party-integration-issues-fixes/iw8u5vDH8VX-5kWU/images/integrations/config.png?fit=max&auto=format&n=iw8u5vDH8VX-5kWU&q=85&s=4f064fb3d8747631ac100fc2c51a8db6" width="500" data-path="images/integrations/config.png" />
    </Frame>

    <Note>
      This basic config connects to your virtual key. You can add advanced features like caching, fallbacks, and guardrails later.
    </Note>
  </Step>

  <Step title="Configure Portkey API Key">
    Now create a Portkey API key and attach the config you created:

    1. Go to [API Keys](https://app.portkey.ai/api-keys) in Portkey
    2. Create new API key
    3. Select your config from Step 2
    4. Generate and save your API key

    <Frame>
      <img src="https://mintcdn.com/portkey-docs-add-third-party-integration-issues-fixes/iw8u5vDH8VX-5kWU/images/integrations/api-key.png?fit=max&auto=format&n=iw8u5vDH8VX-5kWU&q=85&s=989d12de9518c2d6a263d966f5ce5897" width="500" data-path="images/integrations/api-key.png" />
    </Frame>

    <Note>
      Save your API key securely - you'll need it for LiveKit integration.
    </Note>
  </Step>
</Steps>

    ```
  </Step>
</Steps>

# 3. Set Up Enterprise Governance for Livekit

**Why Enterprise Governance?**
If you are using Livekit inside your orgnaization, you need to consider several governance aspects:

* **Cost Management**: Controlling and tracking AI spending across teams
* **Access Control**: Managing which teams can use specific models
* **Usage Analytics**: Understanding how AI is being used across the organization
* **Security & Compliance**: Maintaining enterprise security standards
* **Reliability**: Ensuring consistent service across all users

Portkey adds a comprehensive governance layer to address these enterprise needs. Let's implement these controls step by step.

**Enterprise Implementation Guide**

<AccordionGroup>
  <Accordion title="Step 1: Implement Budget Controls & Rate Limits">
    ### Step 1: Implement Budget Controls & Rate Limits

    Virtual Keys enable granular control over LLM access at the team/department level. This helps you:

    * Set up [budget limits](/product/ai-gateway/virtual-keys/budget-limits)
    * Prevent unexpected usage spikes using Rate limits
    * Track departmental spending

    #### Setting Up Department-Specific Controls:

    1. Navigate to [Virtual Keys](https://app.portkey.ai/virtual-keys) in Portkey dashboard
    2. Create new Virtual Key for each department with budget limits and rate limits
    3. Configure department-specific limits

    <Frame>
      <img src="https://mintcdn.com/portkey-docs-add-third-party-integration-issues-fixes/iw8u5vDH8VX-5kWU/images/integrations/openai/virtual-key-2.png?fit=max&auto=format&n=iw8u5vDH8VX-5kWU&q=85&s=a8c33fd72639726334d697df5a9b5701" width="500" data-path="images/integrations/openai/virtual-key-2.png" />
    </Frame>
  </Accordion>

  <Accordion title="Step 2: Define Model Access Rules">
    ### Step 2: Define Model Access Rules

    As your AI usage scales, controlling which teams can access specific models becomes crucial. Portkey Configs provide this control layer with features like:

    #### Access Control Features:

    * **Model Restrictions**: Limit access to specific models
    * **Data Protection**: Implement guardrails for sensitive data
    * **Reliability Controls**: Add fallbacks and retry logic

    #### Example Configuration:

    Here's a basic configuration to route requests to OpenAI, specifically using GPT-4o:

    ```json theme={null}
    {
    	"strategy": {
    		"mode": "single"
    	},
    	"targets": [
    		{
    			"virtual_key": "YOUR_OPENAI_VIRTUAL_KEY",
    			"override_params": {
    				"model": "gpt-4o"
    			}
    		}
    	]
    }
    ```

    Create your config on the [Configs page](https://app.portkey.ai/configs) in your Portkey dashboard. You'll need the config ID for connecting to Livekit's setup.

    <Note>
      Configs can be updated anytime to adjust controls without affecting running applications.
    </Note>
  </Accordion>

  <Accordion title="Step 3: Implement Access Controls">
    ### Step 3: Implement Access Controls

    Create User-specific API keys that automatically:

    * Track usage per user/team with the help of virtual keys
    * Apply appropriate configs to route requests
    * Collect relevant metadata to filter logs
    * Enforce access permissions

    Create API keys through:

    * [Portkey App](https://app.portkey.ai/)
    * [API Key Management API](/api-reference/admin-api/control-plane/api-keys/create-api-key)

    Example using Python SDK:

    ```python theme={null}
    from portkey_ai import Portkey

    portkey = Portkey(api_key="YOUR_ADMIN_API_KEY")

    api_key = portkey.api_keys.create(
        name="engineering-team",
        type="organisation",
        workspace_id="YOUR_WORKSPACE_ID",
        defaults={
            "config_id": "your-config-id",
            "metadata": {
                "environment": "production",
                "department": "engineering"
            }
        },
        scopes=["logs.view", "configs.read"]
    )
    ```

    For detailed key management instructions, see our [API Keys documentation](/api-reference/admin-api/control-plane/api-keys/create-api-key).
  </Accordion>
