New Channel and New File, plus 5 more triggers
Can do
Archive Channel and Create Channel, plus 30 more actions
Works via
Native nodes, Webhooks, Polling, HTTP Request, JavaScript

Production readiness
Production workflow controls
Use these controls when a workflow needs to stay stable after launch, not just pass a happy-path test.
01
Retry failed API calls
Automatically retry temporary failures before a run is marked as failed.
02
Handle 429 / rate-limit responses
Pause, back off, and continue the workflow safely when an upstream API throttles requests.
03
Add fallback branches for missing fields
Route incomplete payloads into a safe branch instead of letting the main scenario break.
04
Prevent duplicates with lookup-before-create logic
Check whether a record already exists before creating a new one in the destination system.
05
Use JavaScript to normalize dates, phone numbers, tags, and statuses
Clean and standardize values before mapping them into downstream fields.
06
Store execution logs for debugging
Keep a trace of what happened in every run so production issues are easier to inspect.
07
Route failed runs to email or a database
Notify the team or save failures for follow-up when a run cannot complete successfully.
08
Manually rerun failed executions
Replay a failed run after the issue is fixed without rebuilding the scenario from scratch.
Example payload

Slack + Webhook workflows
One-click templates — customise in minutes, no code required.
Automatically capture leads from website, sync to CRM or Sheets, notify team in Slack
This template receives a website lead on a Latenode webhook, creates or updates the HubSpot contact, appends a row in Google Sheets, and posts name and email to a Slack channel. Paste the webhook URL into your form or site. Connect HubSpot, Google Sheets, and Slack, then map email, name, and message on those steps.

Automate blog publishing with AI-generated content and CMS integration
This template turns a topic webhook into a WordPress.com post. Perplexity gathers sources, ChatGPT writes title, excerpt, slug, and HTML, and JavaScript assembles the body. WordPress.com publishes, then Gmail and Slack send the live URL and Notion stores the row. Connect WordPress.com, Gmail, Slack, and Notion. ChatGPT and Perplexity are Latenode AI steps, so you do not paste an OpenAI key.

Image moderation alerts
This template starts when a webhook receives an image URL, scores it with Sightengine in JavaScript, and posts a Slack message when the image should be blocked. Connect Slack and put the Sightengine API key in that JavaScript node. Point your upload pipeline at the webhook URL.

GitHub release automation: Generate notes, draft releases, Slack notify
This template starts when you post owner, repository, and branch to a Latenode webhook. GitHub searches merged pull requests. JavaScript groups them by label, writes the notes, and creates a draft GitHub release. Slack posts a summary to the channel you choose. Connect GitHub and Slack. Put the GitHub token for the draft release in that JavaScript node.
15s$0.0009
Automatically notify Slack when new Basecamp 3 to-dos are created
This template posts a Slack message when Basecamp 3 creates a to-do. Basecamp sends the event to a Latenode webhook. JavaScript reads title, due date, and assignee. Slack posts that summary in the channel you choose. Connect Slack. If you poll Basecamp instead of a webhook, put the Basecamp access token in the JavaScript node.
7s$0.0005
Dialpad call alerts
This template starts when Dialpad posts a call event to a Latenode webhook. JavaScript reads caller, state, and duration, Slack posts a channel message, and an HTTP request sends the same payload to the URL you set. Put the Dialpad API key in that JavaScript node if you verify the signature or fetch extra call fields. Connect Slack. Put any destination API token on the HTTP request.
