Have you tried https://pipedream.com? You can run Node.js (with any npm package) on webhook/http requests, emails and schedules for free. It also manages auth (including oauth token generation and refresh) for popular apps like Google Sheets, Discord, Slack and Airtable -- just use the auths object to reference tokens and keys in code.
Paid tiers are coming soon, and if you hit our daily compute limit before that, we're happy to raise your limit to make sure your workflows run without issue.
Let me know if you have any other questions! Feel free to reach out to me directly at dylan [at] pipedream [dot] com.
