how can i enable keypad inputs in workflows , basically i am building an workflow of creating surveys in which ai will asks questions and record inputs how to implement this any suggestions

To enable keypad input in your Vapi workflow, add the following to your assistant or workflow node configuration:

json
{
  "keypadInputPlan": {
    "enabled": true,
    "delimiters": "#",
    "timeoutSeconds": 2
  }
}

Use a "Gather" node to collect and store each input as a variable for your survey. For more details, see the [Vapi keypad input documentation](https://docs.vapi.ai/changelog/2025/2/27) and [Gather node guide](https://docs.vapi.ai/workflows/nodes/gather).
