## Overview
This guide walks you through setting up and monitoring your Retell-based voice agents using Cekura's observability suite. Learn how to configure your integration and access powerful monitoring tools.
With auto-fetch enabled, Cekura automatically pulls your call data from Retell's API every 30 seconds—no webhook configuration required.
In your Cekura dashboard, create a new agent or select an existing one with Retell as the voice provider.
In your Cekura Agent Settings page:
1. Select **Retell** as the voice integration provider
2. Add your Retell API key
3. Enter your Retell `agent ID`
Toggle on **Auto-fetch Production Calls** in the voice integration settings.
Make a test call from Retell. Within 30 seconds, your call should appear in the Cekura observability `Calls` section.
Auto-fetch is ideal for getting started quickly or when you can't configure webhooks. For real-time call data, use the webhook-based setup in the other tabs.
Follow these steps to connect your Retell agent with Cekura's observability suite:
In your Retell dashboard, add the observability webhook URL:
```
https://api.cekura.ai/observability/v1/retell/observe/
```
You can configure the webhook at either level:
* **Setting Webhook at Agent level:** Navigate to your agent settings and add the webhook URL for a specific agent.
* **Setting Webhook at Workspace level:** Navigate to your workspace settings and add the webhook URL for all agents in the workspace.
Go to the API keys section in your Retell dashboard. Create/ensure you have at least one API key configured with the webhook tag set.
In your Cekura Agent Settings page:
1. Add the API key from Retell with the tag `webhook`
2. Copy and add your `agent ID` from Retell
Make a test call from Retell (phone number based or webcall). Your calls should now appear in the Cekura observability `Calls` section.
If you already have an existing webhook setup and want to forward the Retell response to Cekura's observability suite:
Set up a forwarding mechanism to send the Retell webhook response to Cekura's observability endpoint:
```
POST https://api.cekura.ai/observability/v1/observe/
```
Include your Cekura API key in the request headers:
```
X-CEKURA-API-KEY:
Content-Type: application/json
```
Forward the Retell webhook response to Cekura with the following request body structure:
```json theme={null}
{
"agent": ,
"voice_recording_url": retell_response["recording_multi_channel_url"],
"transcript_type": "retell",
"transcript_json": retell_response["transcript_with_tool_calls"],
"call_id": retell_response["call_id"],
"call_ended_reason": retell_response["disconnection_reason"]
}
```
