Slack (first channel)

Slack is the first production channel on Open-Wire. Customers install your Slack app into their workspace via OAuth — no Vercel login.

Do you need to publish on Slack Marketplace?

No for private / your-customers installs. Create a Slack app, enable OAuth + Event Subscriptions, and distribute the install link (Rails Agent → Connect does this). Marketplace publishing is only for public discovery later.

Slack app settings to configure

OAuth & Permissions → Redirect URLs

https://openwire.rails-agent.com/api/v1/oauth/slack/callback

Event Subscriptions → Request URL
```
https://openwire.rails-agent.com/api/v1/hooks/slack
```
Subscribe to bot events: app_mention, message.channels, message.groups, message.im, message.mpim.
Bot Token Scopes(OAuth & Permissions). Include join + write so the bot can enter public channels and reply:
```
app_mentions:read
channels:history
channels:join
channels:read
chat:write
chat:write.public
groups:history
groups:read
im:history
im:read
im:write
mpim:history
mpim:read
users:read
```
Public channels: Open-Wire auto-joins via conversations.join when posting. Private channels: someone must /invite @YourBot (Slack does not allow bots to self-join private channels).
Copy Client ID, Client Secret, Signing Secret into Open-Wire env (SLACK_CLIENT_*, SLACK_SIGNING_SECRET).

Install flow

Rails Agent Channels → Connect Slack
Open-Wire returns Slack authorize URL
User approves the app in Slack
Callback stores the workspace bot token on the installation → status active
Inbound events fan out to the agent webhook

Custom bot token

Advanced: paste an xoxb-… token in Custom branding to skip OAuth (sandbox / own Slack app).
