Voice API

Wait

Pauses execution for a fixed number of seconds.

Try in API Playground ↗Sign in to prepare and run this request.
POST/api/v1/voice/call-control/wait

Before you start

Choose the documented wait duration for an existing control session.

Result

Continue according to the resulting call state.

Charges and safe retries

Waiting keeps the call open; normal call charges can continue.

Authentication

Send your account API key in the X-Api-Key header. Keep it on your server; never embed it in browser code.

Request examples

Replace the example values with your own inputs. Examples do not run on this page. Production requests can change your account or incur charges.

Request behavior

Useful inside action chains when you need timing control between prompts.

Response fields

  • status: Request outcome. Read the resource state separately; success does not always mean delivery or completion.
  • call_control_id: Control session reference returned by Create or Answer; use it for subsequent live actions.

HTTP responses

Expand a status to inspect its documented response format and examples. Example prices, IDs and timestamps are illustrative values, not quotes or account records.

200 Successful customer-facing response.
