ForSubs + Beehiiv

Automatically sync verified YouTube subscribers to your Beehiiv newsletter

How it works

When a viewer verifies their YouTube subscription on your ForSubs page and opts in to email updates, their email is automatically added to your Beehiiv publication.

  • Real-time sync - subscribers are added within seconds
  • Source tracking - subscribers tagged with utm_source: forsubs
  • Historical sync - import existing verified subscribers when you connect

Setup Instructions

  1. Log in to your Beehiiv dashboard
  2. Go to Settings > Integrations > API
  3. Create a new API key with "Full Access" permissions
  4. Copy the API key and your API V2 Publication ID (starts with "pub_")
  5. In ForSubs, go to Settings > Integrations > Beehiiv
  6. Paste your API key and Publication ID, then click Connect

Frequently Asked Questions

What data is synced to Beehiiv?

Only the subscriber's email address with utm_source: forsubs for tracking. We never share YouTube account details or subscription data.

Where do I find my Publication ID?

In Beehiiv, go to Settings > Integrations > API. Use the API V2 Publication ID (starts with "pub_").

Do subscribers need to opt-in?

Yes. Subscribers must explicitly provide their email address during verification. We only sync emails from subscribers who opted in.

What happens if the sync fails?

ForSubs automatically retries failed syncs up to 3 times. If all retries fail, you'll receive an email notification with details about the issue.

How do I filter ForSubs subscribers in Beehiiv?

Create a Segment in Beehiiv filtering by utm_source = forsubs to see all subscribers that came through ForSubs.

How do I disconnect Beehiiv?

Go to Settings > Integrations in your ForSubs dashboard and click "Disconnect" next to Beehiiv. This removes the connection but does not delete subscribers already in Beehiiv.

Security & Privacy

  • API keys stored with AES-256 encryption
  • Keys are never exposed in your browser or logs
