Stream cohort

Stream a cohort as JSON with two fields: - `name` - Cohort name (1-50 characters) - `users` - Array of user records (1-1000) **When to use** Stream cohort adds contacts to a campaign programmatically (up to 1000 users per request). Use it when your system already has user records and you do not need to upload a CSV. - **CRM integration** - sync leads or customers from Salesforce, HubSpot, Zoho, or your own database into a campaign - **Webhooks and automation** - push contacts from form submissions, payment events, or internal workflows - **Active campaigns** - queue new contacts to dial within the current schedule (same as Add cohort in the dashboard) - **Scheduled or paused campaigns** - load contacts before the campaign starts, or while it is paused - **Incremental batches** - send multiple API calls over time instead of one large CSV upload For CSV files, use **Upload cohort** instead. The campaign must be **active**, **scheduled**, or **paused**. Processing is asynchronous - poll **Get cohort** until `status` is `completed` or `failed`. **Limits and rules:** - `user_phone_number` is required for every user (E.164 preferred; 10-digit Indian numbers are normalized automatically) - `app_variables` must match variables configured on the agent - `app_overrides` supports only: `initial_language_name`, `initial_state_name`, `initial_bot_message` **Common validation errors:** - No users, or more than 1000 users - Invalid cohort name - Missing `user_phone_number` - Unsupported `app_overrides` key - Unknown `app_variables` for the selected agent.
