About the Slack connectors

The Slack connectors let your app send messages, read conversations, and work with channels and workspace data inside Slack. You can post alerts to team channels, generate digests, power dashboards with Slack data, and tie your app’s workflows directly into Slack. Base44 offers two Slack connectors:
  • Slack User connects as a user in your Slack workspace. It allows your app to read conversations, search channel history, and send messages using the connected user’s permissions.
  • Slack Bot connects as a bot identity in your Slack workspace. It allows your app to send structured messages as a configurable bot for alerts, announcements, and automation workflows.
Slack connector in Base44
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.
Before you begin: You need a Builder plan or higher to use connectors in your app.

​
Slack use cases and prompts

Use Slack or Slack Bot to keep your team in sync, turn conversations into structured data, and connect your workspace to the rest of your tools.

​
Slack User

Use Slack User when your app needs to read Slack data or act with the permissions of a specific Slack user.
Slack User is best for:
  • Reading public and private channel history.
  • Searching messages and conversations.
  • Tracking mentions and replies.
  • Building dashboards and summaries from Slack data.
  • Sending messages as the connected user.

​
Slack Bot

Use Slack Bot when your app needs to send automated or structured messages as a branded bot. You can customize how Slack Bot appears when it sends messages.
Slack Bot is best for:
  • Incident alerts.
  • Release announcements.
  • Broadcast updates.
  • Scheduled summaries.
  • Automation-driven notifications.
To customize how Slack Bot appears, prompt the AI chat directly. For example: Send messages as "Deploy Bot" with a rocket emoji icon.
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.These examples typically use Slack Bot, since they focus on automated and structured message delivery.Example prompts:
Send a Slack alert to #incidents when a deployment fails, including environment, commit hash, and error summary.

Post a formatted incident summary to #ops with severity, owner, and resolution time whenever an incident is marked resolved.

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

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.

Send a weekly release recap to #announcements every Friday at 4pm with links to merged pull requests.
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.These examples typically use Slack User, since they require reading Slack data.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 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 User or Slack Bot 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.Depending on the workflow, you may use Slack Bot to send automated updates, or Slack User to read and transform Slack data inside your app.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.

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

Mirror messages from #customer-feedback into a structured feedback table inside my app.

Track all mentions of our product name across public channels and display them in a dashboard.

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

  3. Review the Action required and Required permissions in the side panel.
  4. Click the Connect button shown in the side panel to authorize the required Slack connector.
  5. In the Slack window that opens:

FAQs

Click a question below to learn more about the Slack connectors.
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 User or Slack Bot, 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 or Slack Bot 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).
Slack Bot must be explicitly added to private channels before it can post messages there.In your Slack workspace:
  1. Open the private channel.
  2. Click the channel name.
  3. Go to the Integrations tab.
  4. Click Add apps and select Base44.
Once added, your app’s Slack Bot can post messages in that channel.
