# Upload cohort

POST https://apps.sarvam.ai/api/scheduling/v1/orgs/{org_id}/workspaces/{workspace_id}/deployments/{deployment_id}/cohorts/upload
Content-Type: multipart/form-data

Upload a cohort of users for a deployment. When a known user calls in, the agent receives their personalized variables (name, balance, language, etc.) for a tailored conversation.

Upload as multipart form-data with three fields:
- `name` — Cohort name (1–50 characters)
- `cohort_file` — CSV file with a header row and user data
- `cohort_transformation_file` — JSON file that maps CSV columns to phone numbers and agent variables

Reference: https://docs.sarvam.ai/conversations/api/deployments/cohorts/upload
