Slack

Cauldron’s Slack app posts review updates to channels your team picks, and keeps the Slack thread under each review message in sync with the asset’s Thread. Optionally, it can post your studio’s wins (level-ups, feats, new members) to a channel of their own.

What posts to a brand’s review channel:

• One asset submitted for review: a message with the asset image and Approve and Request changes buttons.
• Several assets submitted, approved or sent back at once: one summary per brand, with a contact sheet of thumbnails and a link to the brand’s review queue.
• A decision made in Cauldron: approvals and change requests post to the channel too.

Setting it up has three parts:

1. An owner or admin adds Cauldron to your Slack workspace once, from Settings → Studio.
2. Someone with access to the brand picks a channel for each brand’s review updates, plus a channel for studio wins if you want one.
3. Each person who wants to review from Slack connects their own Slack account from their profile.

Add Cauldron to Slack

You need to be a studio Owner or Admin to do this.

1. Open Settings → Studio and find the Slack section.
2. Click Add to Slack. Slack opens and lists what Cauldron is asking for (see Permissions).
3. Choose the Slack workspace if Slack asks, then click Allow. Slack’s page says App is not approved by Slack. That’s expected: Cauldron isn’t listed in the Slack Marketplace, so Slack shows this for every install. It doesn’t change what Cauldron can do.
4. You come back to Studio settings, see Slack connected., and the section reads Connected to followed by your Slack workspace’s name.

If you click Cancel on Slack’s page, you’ll see Slack install canceled. and nothing changes.

Your Slack admin may need to approve Cauldron. Some Slack workspaces only let admins install apps. If yours does, Slack offers to send a request to your Slack admins instead of showing Allow. Once they approve it, click Add to Slack again.

One Slack workspace per studio

A studio connects to one Slack workspace, and a Slack workspace can be connected to one studio. If the Slack workspace you pick is already connected to a different Cauldron studio, you’ll see That Slack workspace is already connected to another studio. Disconnect it from that studio first, or pick a different Slack workspace.

Enterprise Grid organization-wide installs aren’t supported. Install Cauldron into a single workspace in the organization instead.

Choose channels

Cauldron only posts to channels you choose. Nothing posts until a channel is set.

1. In the Slack channel, type /invite @Cauldron and send it. This works the same for public channels, private channels, and Slack Connect channels shared with another company.
2. Copy the channel ID: click the channel name, open the About tab, and the ID is at the bottom. It starts with C, like C0123ABCDEF.
3. Paste the ID into the field in Cauldron (see the table below) and save. Saving sends a test message to the channel, so you can see it worked. If the message can’t be delivered, nothing is saved and you see why.

To stop posting, clear the field and save.

Where	Field	What posts there
A brand’s Integrations tab → Slack row	Channel ID	Submitted, approved and changes-requested updates for that brand, with the asset image and review buttons. See Brands
Settings → Studio → Slack	Slack channel for studio updates	Level-ups, feats, new members joining, and a monthly leaderboard shout-out. See Studio settings

Each brand posts to its own channel. There’s no studio-wide default: a brand with no channel set posts no review updates to Slack. Until Slack is connected for your studio, the studio channel field is grayed out and the brand’s Slack row offers only Connect, which takes an Owner or Admin to Studio settings.

You can also set these channels by asking Claude, or another AI tool connected to Cauldron. Owners and admins can set any of them, and brand managers can set the review channel for their own brands. Saving from Claude sends the same test message. See Connected AI tools.

Connect your own Slack account

When you click Approve or Request changes in Slack, Cauldron needs to know which studio member you are. It checks two things, in order:

1. A linked Slack account. You link it once from your profile (steps below).
2. Your email. If your Slack email matches the email of someone in this studio, Cauldron treats you as that person and remembers the link.

If neither matches, Slack shows you a private note asking you to connect Slack in your profile, and the asset doesn’t change.

To link your Slack account:

1. Make sure your studio has added Cauldron to Slack.
2. Open your profile and find Slack account under Preferences.
3. Click Connect Slack and approve on Slack’s page. You come back to your profile and see Slack connected.

After that:

• Studio updates @-mention you instead of only naming you.
• Approve and Request changes in Slack act as you, with your brand role. If you can’t approve on that brand in Cauldron, you can’t approve from Slack either.
• Your Slack replies on a review thread show on the asset under your studio name.

Your Slack account has to belong to the Slack workspace your studio connected. If it doesn’t, you’ll see That Slack account belongs to a different workspace than the studio bot. To unlink, click Disconnect on the same row. See Profile.

Working with other companies over Slack Connect

If you share a channel with another company through Slack Connect, you can use it as that brand’s review channel. Invite the bot to the shared channel and paste its ID as the brand’s review channel.

People from the other company can reply in the review thread without a Cauldron account. Their replies show on the asset as “Name · via Slack”. Only studio members with the right brand role can approve or request changes. Their click on those buttons gets a private note saying Cauldron couldn’t match their Slack account, and the asset doesn’t change. Reviewing has more on Reviewing from Slack.

Permissions

When you add Cauldron, Slack asks for these permissions on behalf of the Cauldron bot. Cauldron never asks for a token that acts as you.

Permission	Why Cauldron needs it
Send messages, and post under a person’s name and avatar	Post review updates, and mirror studio comments into Slack under the commenter’s name
Upload and read files	Attach the asset image to review messages
View people and their email addresses	Match Slack users to studio members so @-mentions and review buttons reach the right person
Read messages in channels, private channels and direct messages it’s in	Bring replies in a review thread back to the asset. The bot only sees conversations it has been added to
View basic channel info, and join public channels	Check that a channel you set exists and that the bot can post there
Read and add reactions	Keep reactions in sync between Slack and the asset
Read @-mentions, work as an assistant, and read and unfurl links	Requested now for Slack features that are coming, so you won’t have to add Cauldron again when they arrive

What Cauldron stores

• The bot token for your Slack workspace, encrypted, for your studio alone. It’s used only to post to the channels you choose and to read replies in synced review threads.
• Replies and reactions from synced review threads, with the names and avatars of the people who made them. These are kept as part of the asset’s history.
• Your Slack identity, if you connect your own account. That’s your Slack user and workspace IDs, never a personal Slack token.

Cauldron never uses Slack data to train AI models. The Privacy policy has the full details.

Disconnect

An Owner or Admin can disconnect at any time from Settings → Studio → Slack. Click Disconnect and confirm. Cauldron deletes the bot token and revokes it with Slack straight away, then stops posting to your Slack workspace.

Removing the Cauldron app from Slack’s side (through your workspace’s app management) does the same thing: the token is deleted as soon as Slack tells Cauldron.

Either way:

• Comments already synced stay on the asset, as part of its history, until the asset is deleted permanently from the Archive.
• Review messages already in Slack stay where they are, but their buttons stop working.
• The channel IDs you set stay saved. If you add Cauldron to Slack again, invite the bot back to each channel.

Troubleshooting

What you see	What to do
The Cauldron bot isn’t in that channel — /invite it there first	Type /invite @Cauldron in the channel, then save the channel ID again
Channel not found — double-check the channel ID	Copy the ID again from the channel’s About tab. Paste the ID itself, like C0123ABCDEF, not the channel name. If the channel is private, invite the bot first
Slack isn’t connected on this studio	An Owner or Admin needs to add Cauldron to Slack first
That Slack workspace is already connected to another studio.	See One Slack workspace per studio
Couldn’t connect Slack. Try again.	Try Add to Slack again. If it keeps failing, check that you aren’t installing org-wide on Enterprise Grid, then contact us
A click on Approve says it couldn’t match your Slack account	Connect your own Slack account from your profile, then click again
Add to Slack isn’t shown	Only Owners and Admins see it. Ask one of them to connect Slack
Review updates stopped arriving	Check Settings → Studio still reads Connected to …. If it doesn’t, someone disconnected or removed the app from Slack, so add it again and re-invite the bot. If it does, check that the brand still has a review channel set and that the bot is still in that channel
