Slack notifications deliver Roleplay Sessions activity directly to each learner's Slack inbox as a 1:1 direct message. Learners get notified when a roleplay is assigned, when they complete one, and when an assignment is overdue — without leaving the tools they already use. Setup is a one-time authorization by an organization admin, after which messages are dispatched automatically.

## What learners receive

Once Slack is connected, learners receive a 1:1 DM for each of the following events:

- **On assignment**— a DM with the roleplay title, thumbnail, and a link into Synthesia Learn App to get started.  
- **On completion**— a DM confirming completion with a link to view results.  
- **Overdue reminders** — up to three escalating reminders if a roleplay isn't completed by its due date: a first nudge 1 day overdue, a stronger reminder at 3 days, and a final reminder at 7 days. Each links straight back to the roleplay.

## Permissions and scope

The Synthesia Slack notifications is outbound-only. It sends direct messages and looks up users by email — it does not read channels or message contents.

| Provider | Authentication | Scope |
| --- | --- | --- |
| Slack | OAuth 2.0 (bot token) | DMs only — outbound, no channel posting |

## Connect Slack

As an organization admin in Synthesia:

1. Go to the Learner Portal (learn.synthesia.io) → **Manage** → **Integrations**.
2. Select Slack.
3. Authorize the Synthesia Slack app for your workspace.

Once authorized, the integration is live and DMs are dispatched automatically on assignment, completion, and reminder events.

## How learners are matched

Learners are matched to Slack users by email. The Synthesia app looks up each learner's email in your Slack workspace; if a match is found, that learner receives DMs. Notifications follow the learner's status in Synthesia — only active learners receive them.

## Things to know

- **No per-learner opt-out.** If your org has Slack connected and a learner's email matches a Slack user, they receive DMs. There is no per-learner toggle.
- **No notification preferences.** Assignment, completion, and reminder DMs all fire together — learners can't subscribe to only one type.
- **No digest or batching.** Each event is its own DM, so multiple assignments at once means multiple DMs.
- **Messages are read-only.** Learners can't reply to the DMs; the app is outbound-only.
- **Fixed reminder cadence.** Reminders are sent at 1, 3, and 7 days overdue. The timing and number of reminders can't be changed.
- **One workspace per organization.** An admin can connect only a single Slack workspace.
- **No custom message copy.** Title, thumbnail, and CTA are templated and can't be customized.
