# Bulk Subscribe

`POST /slack/enrollments/bulk`

## Request

- Base URL: `https://api.traversal.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.traversal.com/slack/enrollments/bulk`
- Auth: none declared

## Request body

- BulkCreateSlackChannelEnrollmentsRequest
  - `slack_channel_names` string[], required
  - `mode` 'MANUAL' | 'AUTO' | 'CUSTOM' | 'READ_ONLY', required: How Traversal is wired into a chat channel. Stored as ``slack_channel_enrollments.mode``. A channel with no enrollment row is implicitly ``MANUAL``, except a Slack mention, which uses the org default so it agrees with the row the join handler is about to write. Storing an explicit ``MANUAL`` row lets the channel carry per-channel state (like ``custom_instruction``) without enabling auto-triggers. Removing a channel from Channel Management entirely is a separate act (archiving the enrollment), not a mode. ``READ_ONLY`` is the one mode that suppresses *outbound* behavior rather than selecting a flavor of it: Traversal keeps ingesting and storing every message, and answers every interactive surface with a fixed notice instead of doing work. It is only offered while its organization's gate is on -- see ``engagement_policy``. Existing ``READ_ONLY`` channels keep the mode when that gate is turned back off, so nothing starts talking again behind a customer's back.
  - `custom_instruction` string, nullable
