About the Slack connector

The Slack connector lets your app send messages, read conversations, and work with channels and workspace data using a single Slack connection. You can post alerts to team channels, generate digests, power dashboards with Slack data, and tie your app’s workflows into your Slack workspace. The Slack connection is shared across your app. When you connect Slack, you authorize one Slack account for that app, which can send to public channels, private channels, DMs, and group chats in that Slack workspace. Everyone who can edit the app uses the same shared Slack connection and sees the same Slack-powered data inside the app.

Important: Connectors are app-level, shared connections. Do not use the Slack connector if each person using your app needs to connect their own Slack account. For per-person Slack login, create a custom OAuth flow with backend functions.

​
Slack use cases and prompts

Use the Slack connector to keep your team in sync, turn conversations into data, and connect your workspace to the rest of your tools. You can post alerts, generate summaries, power dashboards, and trigger workflows that run across your app and Slack.
Keep your team updated by sending structured messages to channels, group conversations, and DMs whenever something important happens in your app. Share new tickets, incidents, deployments, signups, or sales in real time so the right people can respond.Example prompts:
Post a message to #support when a new ticket is created, including the ticket ID, title, priority, and a link.

Send a daily summary of completed tasks to #team-updates at 5pm, grouped by assignee.

Notify me in a direct message when a high-value sale is made in my app, with customer name and order value.

Share important updates in the #announcements channel when a document is approved in this app.

Send alerts to a Slack channel when deadlines are approaching for tasks due in the next 24 hours.
Read Slack conversations and transform them into dashboards, reports, and searchable views in your app. Track mentions that need a reply, summarize busy channels, or create filters to quickly find past decisions and action items.Example prompts:
Build a dashboard showing where I have been mentioned in Slack and which messages still need a reply.

Summarize #product and #support from the past 7 days and post a clean digest to #leadership.

Create a search view that lets me filter Slack messages by keyword, channel, sender, and date range.

Show a list of pinned messages from #support in my app as a structured task list with links back to Slack.

Highlight any message in #incidents that contains the word "urgent" and surface them in a dedicated view.
Connect Slack to other systems you integrate with Base44. Route events from data warehouses, CRMs, documents, and spreadsheets into Slack, or mirror Slack activity into other tools so teams see the same information wherever they work.Example prompts:
Post a message in Slack when a new row is added to my connected Google Sheet of customer feedback, with the feedback text and rating.

Send a Slack alert when my BigQuery-powered data agent finds an unusual drop in conversions or revenue.

Share a link to each newly created Notion page for client briefs in the #project-updates channel.

Notify #sales when a Salesforce or HubSpot deal moves to the Closed Won stage, including deal size, owner, and expected close date.

Post a weekly KPI report to Slack that pulls metrics from BigQuery and links to the dashboard in this app.
When you describe multi-tool flows in the AI chat, be explicit about which events should trigger which Slack messages and what details to include in each post.

  3. Review the Action required and Required permissions in the side panel.
  4. Click Connect to Slack.
  5. In the Slack window that opens:
    1. Select the Slack workspace you want to connect.

After you create Slack-powered functions, ask the AI to add structured formatting to your Slack messages, such as bold text, bullet lists, or code blocks, to make alerts easier to scan. Then test each flow by triggering the event and checking the target Slack channel.

FAQs

Click a question below to learn more about the Slack connector.
No. Each app uses one shared Slack account. To post from multiple Slack accounts or workspaces, create separate apps or build a custom Slack integration with backend functions and separate OAuth flows.
No. Connectors are app-level. When you connect Slack, you connect a single Slack account that all flows in the app use.To let each person connect their own Slack account, you need a custom per-person OAuth flow using backend functions and the Slack API. This includes managing redirects, storing user tokens, and handling token refresh.
  1. Go to your app dashboard and click Integrations.
  2. Click the My integrations tab.
  3. Find Slack and click the More Actions icon , then Switch account.
  4. Complete the Slack authorization flow for the new workspace.
Yes. When you describe Slack messages in the AI chat, you can specify:
  • The text content and formatting.
  • Whether to include fields like IDs, links, and counts.
  • How often and when messages are sent.
You can also open the generated backend functions in Dashboard → Code → Functions to fine-tune the message payload (for example, using blocks for more complex layouts).
