This template watches a Slack channel for public messages, reads the first website URL in JavaScript, captures the page with a headless browser, and uploads the screenshot back to the same channel. Connect Slack and put Slack access on that connection. Watch the channel that should trigger captures.
Latenode bills workflow runtime in CPU seconds. The first 10,000 CPU seconds are free each month, then usage follows pay-as-you-go CPU-second pricing. Plug-and-Play (PnP) AI nodes are billed separately—each PnP token is $1 USD, charged pay-as-you-go at vendor cost plus a small processing fee, with no API keys required.

The scenario starts when a public message is posted in the Slack channel you choose.
JavaScript pulls the first URL from the message text. The run stops if the message has none.
A headless browser opens the URL and takes a screenshot.
Slack uploads the image to the same channel.
Add a Slack connection with access to the channel you want to watch and permission to upload files there.
Add a Slack trigger for new messages posted to that channel.
In JavaScript, extract the first website URL. Open it in a headless browser, take a screenshot, and upload the file to Slack. Send a test message with a URL and confirm the image lands in the channel.

This template watches Slack for new files, downloads each file, and uploads a copy to a Google Drive folder. Use it as a backup so channel attachments are not only in Slack. Connect Slack and Google Drive, then pick the channel to watch and the Drive folder that should hold the copies.
This template starts when Slack sends a saved-item event to a Latenode webhook. JavaScript reads the message text with the Slack API. Put the Slack token in that JavaScript node. Google Tasks creates a task with that text as the title and the permalink in the notes. Connect Google Tasks and point Slack's saved-item events at the webhook URL.
This template receives Slack reaction events on a webhook, keeps the run when the emoji matches the one you chose, loads the original message from Slack, and creates a Linear issue with that text. Connect Slack and Linear. Paste the Latenode webhook URL into Slack Event Subscriptions for reaction events. Put the Slack bot token on the Slack connection and the Linear API key on the Linear connection.
