Log UK Apify grant alerts to Notion and send closing-soon Slack notifications

Description

Quick overview
This workflow receives an Apify webhook when the UK Grant Alert Engine actor run completes, fetches the matched grants dataset from Apify, logs all new matches to a Notion database, and posts a Slack alert only for grants flagged as closing soon.

How it works
Receives an Apify webhook request when the actor run completes and immediately replies “OK” to prevent retries.
Calls the Apify dataset items API to fetch up to 200 grant match records from the run’s default dataset.
Filters the dataset to keep only items marked as new matches.
Creates a Notion database page for each new grant with key fields like funding body, award range, deadline, days to close, matched keyword, and application URL.
Checks whether the newly logged grant is marked as closing soon.
Formats and posts a closing-soon alert message to a specified Slack channel.

Setup
Create an Apify webhook for your UK Grant Alert Engine actor that points to this workflow’s Webhook URL (path apify-uk-grants-notion).
Replace YOUR_APIFY_API_TOKEN in the Apify dataset request with your Apify API token.
Create a Notion database with the required properties and replace YOUR_NOTION_GRANTS_DATABASE_ID, then add your Notion API credentials in n8n.
Add Slack OAuth2 credentials in n8n and set YOUR_SLACK_CHANNEL_ID to the channel that should receive closing-soon alerts.
