Before creating a campaign, upload your contacts CSV to get a source_url.
Set telephony_configuration_id to pin the campaign to a specific telephony configuration. If omitted, Menace Voice falls back to the organization's default outbound configuration — supplying an id that doesn't exist in your organization returns 400 telephony_configuration_not_found.
The time_slots field controls when Menace Voice is allowed to place calls. If omitted, calls can be placed at any time. The timezone field applies to all time slot windows.
Once created, the campaign is in draft status. Call Start to begin dialing.
