Slack Alerts (Incoming Webhook)

Post a short summary to a Slack channel whenever a scheduled scrape finishes.

Setup Steps

1. Go to api.slack.com/apps → Create New App → From scratch, and pick your workspace.
2. Open “Incoming Webhooks”, turn it on, then click “Add New Webhook to Workspace” and choose a channel.
3. Copy the webhook URL (it starts with https://hooks.slack.com/).
4. In Lection, set the delivery channel to "Slack" and paste the URL.

Mapping Tips

• Each message shows the schedule name, status, row count, and an “Open dataset” button.
• The message links to the export instead of pasting rows, so large runs stay readable.

Payload Highlights

• Slack-formatted message (text + blocks), not the raw JSON payload.
• Need the full rows in Slack? Use a Zapier, Make, or n8n webhook and format them there.

Test Checklist

• Paste the webhook URL in Lection and save the schedule.
• Use “Run now” on the schedule and wait for it to finish.
• Check the channel for the run summary and open the dataset link.
