Create a webhook in Slack, then add it to a new or existing app to post task updates, and fix common issues. Note: Slack integration is available on the Builder plan and above. *** ## Part 1: The Slack side If you already have your Slack webhook, you can skip ahead to [Part 2 - The Base44 side.](https://docs.base44.com/Integrations/Slack-integration#part-2%3A-the-base44-side) Slack API apps page with a Create an App button * Head over to: [https://api.slack.com/apps](https://api.slack.com/apps) * Click **Create an App** * Click **From Scratch** Slack dialog offering to create an app from a manifest or from scratch Slack dialog with an app name field and a workspace picker * For example: `Base44 Notifications` * Pick your workspace Slack Incoming Webhooks settings with the activation toggle switched on * In the sidebar, open **Incoming Webhooks** * Toggle **Activate Incoming Webhooks** to On Slack webhook list, empty, with the Add New Webhook button outlined * Scroll down on this same page * Click on **Add New Webhook to Workspace** * Select the channel where messages should appear * Click **Allow** * Your webhook URL should look similar to this: `https://hooks.slack.com/services/T000/B000/XXXXXXXX` * Keep this handy, you'll use this in Base44 when it prompts you for the **secret**. *** ## Part 2: The Base44 side Once you have your Slack webhook URL, you can connect it to Base44 in 2 different ways: * Choose this path if you are starting a new app from scratch. * Choose this path if you are already in the midst of building and would like to integrate Slack into an existing app. *** ### Option A: Ready-made integration (for new apps) * In Base44 click on Integrations Base44 home prompt page with Integrations outlined in the top navigation * Select **Slack** * Select **Use this Integration** Slack integration page in the Base44 catalog with a Use this integration button Slack integration setup with a field to enter the webhook URL * When prompted, paste your `SLACK_WEBHOOK_URL` * Type out your first prompt to scaffold the app * Sample prompt: `Build me a to-do list app "Todo" that will send a message to my Slack channel every time a task is created or the status changes to Done, In Progress, or Deleted.` Slack channel receiving task created and task completed messages posted by a Base44 app * Creating or updating your tasks should now post a message into your Slack channel * If nothing appears, double-check: * The webhook belongs to the correct channel * The secret is saved correctly * Posts are happening from the backend only (not the browser) *** ### Option B: Instant integration (connecting Slack to an existing app) Preview of a to-do app with All Tasks, Active and Completed filters and a list of tasks * Here's the prompt that we typed out in the AI chat to build our sample app: \ `Build me a to-do list app called Todo` AI chat explaining how to get a Slack webhook URL, with a button to add it, beside the app preview * Sample prompt for the AI Chat: `Connect this app to Slack using an Incoming Webhook. Ask me for SLACK_WEBHOOK_URL and save it as a Secret. Post to Slack from the backend only.` Dialog with a field to enter the Slack webhook URL and a save button * When prompted by the AI Chat, click on `Update SLACK_WEBHOOK_URL secret` * Then paste your webhook URL into the pop up window * Tell the AI chat how you want your app to use Slack * Sample prompt: `Hook the backend Slack post into the todo lifecycle:` `- On create: post "New task: {title}"` `- On status change: post "Task status updated: {title} -> {status}"` `- On delete: post "Task deleted: {title}"` `Use the channel from SLACK_WEBHOOK_URL. If a call fails, show a small toast and continue.` Slack channel receiving task created and task completed messages posted by a Base44 app * Create a task. * Change its status to *In Progress*, then *Done*. * You should see the corresponding messages land in your Slack channel. *** ## Troubleshooting * **No message in Slack** → The webhook might point to a different channel. Create a new one for the right channel. * **Frontend errors (401 / CORS)** → Don’t call Slack directly from the browser. Always post from the backend. * **Webhook rotated or revoked** → Paste the new webhook into Base44 Secrets. * **Workspace blocks custom apps** → Ask a workspace admin to approve your Slack app. *** ## Common use cases This integration is great for keeping your team in the loop without leaving Slack. Some popular patterns include: * **Task tracking:** Post a message every time a new task is created, updated, or completed in your app. * **Team notifications:** Send alerts to a shared channel when key events happen, like a status change to *Done*, *In Progress*, or *Blocked*. * **Error reporting:** Have your backend send a Slack message when something fails (for example, a payment or data sync) so you can react quickly. * **Daily summaries:** Combine with Zapier or another integration to push a morning digest into Slack, showing todos created or completed yesterday.
