Configure Vercel to forward logs

Configure a Log drain to send your logs to Better Stack:

  1. Go to Vercel dashboard → Team Settings → Log Drains.
  2. Click Add Log-Drain button and select Custom Log Drain.
  3. Choose projects and sources to collect logs from.
  4. Select NDJSON as your delivery format.
  5. Choose your target projects.
  6. Get your source token and ingesting host from Sources → Configure.
  7. Enter https://$INGESTING_HOST as your Endpoint.
    The Vercel's form might instruct you about domain verification, but the step should be optional for Better Stack URLs and you should be able to just click on Verify it without doing anything special.
  8. Enable Custom Headers, and add a header with Key Authorization and Value Bearer $SOURCE_TOKEN.
  9. Click the Add Log Drain button and you're done.

You should see your logs in Better Stack → Live tail.

Not seeing any logs?

Click the Test Log Drain button in Vercel to send a sample log. You should see the log in Live tail.
