Getting started with Vapi
- Log in to the Vapi dashboard and click on Evals in the left sidebar under Observability.
- Click Create Evaluation to start setting up your test.
- Configure the basic settings by entering a Name and Description for your evaluation.
- Add conversation turns by clicking Add Message, selecting message types, and configuring the evaluation criteria with an AI Judge.
- Click Save Evaluation to store your evaluation setup.
- Select Assistant or Squad as your target type under the Run Test section and click Run Evaluation.
- View your test results and click View Details to inspect the full conversation transcript.
Tips
- Before relying on an AI judge, check that it accepts a correct response and rejects an invalid one.
- Evals run at the text and model layer, so use Simulations for complete conversations and controlled real calls for testing the phone path and live integrations.
- You can run evaluations with transient assistant or squad configurations by providing assistant or squad objects instead of IDs in the target.
