Streaming Cohorts (JSON Cohort Uploads)

Voice Agents

Cohort uploads now support JSON via the Stream cohort API, for teams that want to add contacts programmatically instead of uploading a CSV in the dashboard. Send up to 1,000 users per request, and add contacts to a campaign while it’s running - they queue to dial within the current schedule. See Cohorts.

Code Tools

Voice Agents

Added Code Tools, letting you upload a custom Python file to define tools that go beyond the built-in API and data-validation tools. Available on request - contact us to get access.
