You can test your agents directly on our platform without configuring API keys. Cekura will use internally generated transcripts for testing purposes. For a simpler setup without API keys, check out our guide on testing custom agents.

​
Prerequisites

To successfully integrate your VAPI agent, you will need the following:
  • A Cekura account
  • A VAPI account with a deployed Voice Assistant.
  • Your VAPI API Key (for Cekura’s Organization Settings).
  • Your VAPI Assistant ID (for the Cekura Agent configuration).

​
Testing with VAPI

This guide walks you through setting up and testing your Voice AI agents built on the VAPI platform using Cekura. By linking your VAPI Assistant to Cekura, you can run automated test suites, analyze call performance, and ensure agent quality.

​
Creating and Testing Your Agent

The quickest way to get started is by creating a new Agent in Cekura, which allows you to link your specific VAPI Assistant ID and provide your API Key if it hasn’t been configured globally.
1

Create a New Agent

  1. Log in to your Cekura Dashboard
  2. Click the Add Agent or Create Agent button. Createanagent Pn
2

Configure Agent Settings

  1. Navigate to the Agent Settings panel.
  2. In the Provider dropdown, select VAPI.
  3. Enter the specific VAPI Assistant ID of the agent you want to test.
  4. Enter your VAPI Private API Key in the designated field.
  5. Click Save to create and configure the agent Vapi Agentsettings Pn
Prerequisite Note: The VAPI Assistant ID is required to link a specific agent, and the VAPI Private API Key is required for Cekura to authenticate and communicate with VAPI.

Run Your First Test

Once your VAPI Agent is configured:
  1. Go to Simulation → Evaluator.
  2. Click Generate Evaluators to auto-create basic metrics.
  3. Choose a Scenario from the list (or create one).
  4. Click the ▶️ Play button next to it to start your first test.
  5. Monitor the test in Simulation → Runs Overview.
  6. View transcripts, audio, and metrics in Results.
  7. Use Re-run Failed or Lab → Optimize to refine and rerun.

Value of VAPI Integration

Integrating your VAPI Assistant with Cekura unlocks powerful testing and observability features:
  • Detailed Tool Call Information: You are able to see granular data on tool calls made by your VAPI agent during a conversation, which is critical for debugging complex workflows.
  • Metadata Access: You are also able to access any metadata available from VAPI calls, enabling richer, context-aware evaluations of agent performance.
  • Automated Outbound Calling: You can use Cekura’s infrastructure for automated outbound calling to run large-scale, performance-driven test campaigns. Outboundvapi Pn
This setup is recommended as it configures your VAPI API Key once, making it available across all agents within your project. If you complete this step, you will not need to enter the API Key when creating subsequent VAPI agents.
  1. Log in to your Cekura Dashboard.
  2. Click on the Settings button (usually on the top right of the navigation bar).
  3. Navigate to the Provider API Keys tab.
  4. Locate the VAPI section.
  5. Enter your VAPI Private API Key in the designated field.
  6. Click Save Changes. Vapi Providerapi Pn
