Setup

​
Choose your voice platform and stay on that path.

If you use Retell, stay in the Retell section. If you use Vapi, stay in the Vapi section. Mixing both paths creates avoidable setup mistakes.

Retell setup

Start with the Retell connection guide, then move through functions, variables, webhook setup, and example scripts.

Vapi setup

Start with the Vapi connection guide, then move through functions, variables, webhook setup, and example scripts.

​
For either platform

  1. Connect your platform.
  2. Configure function tools.
  3. Review dynamic variables.
  4. Confirm webhook behavior.
  5. Use example scripts only after the core setup works.

​
What this section covers

  • Platform connection setup for Retell and Vapi.
  • Function tool setup for each platform.
  • Dynamic variables.
  • Webhook behavior.
  • Example scripts and prompts.
If you only use one platform, ignore the other section entirely and keep your path simple.
