Next.js + beehiiv integration

Plandalf does not currently create a beehiiv subscriber after a purchase, and beehiiv has no native Plandalf steps. A Next.js app can host the checkout, and a beehiiv post can link to a hosted checkout. If you build subscriber sync yourself, a Send Webhook step can call a route handler of yours.

1. Publish the offer and copy the links

   In Plandalf publish the offer, then copy its hosted checkout link and its Test mode link from the Share tab.

2. Add the checkout to Next.js

   Load the SDK in a client provider with next/script and render a data-plandalf-present button after the SDK is ready. Keep the provider under the root layout so one script serves every route.

3. Link from beehiiv

   In a beehiiv post or page add a button that points to the hosted checkout link. Send yourself a preview first and click through on the received email.

4. Add a countdown if needed

   In Plandalf Promos, Emails choose beehiiv and copy the snippet. In the beehiiv editor type /, pick HTML Snippet and paste it, then preview before sending.

5. Decide how buyers reach beehiiv

   If you want paying buyers as subscribers, that needs a separate, consent-aware step. beehiiv's API can create a subscription with an email, so a route handler fed by Send Webhook is one way to build it, and the work is yours.

• Plandalf's beehiiv page says plainly that native subscriber or buyer sync is not currently available.
• The countdown snippet needs an eligible beehiiv plan or trial for the HTML Snippet block, per Plandalf's beehiiv guide.
• Use a public checkout host before publishing a beehiiv page or sending a campaign, because a local test host will not open for readers.
• beehiiv's create subscription endpoint takes an email and a bearer token with the subscriptions write scope. Whether and when to confirm by email is your choice through its double opt-in setting.

Does Next.js integrate with beehiiv?

Plandalf does not connect them. A Next.js site can host a Plandalf checkout and beehiiv posts can link to it, but buyers are not added to beehiiv automatically.

Can I add Plandalf buyers to beehiiv as subscribers?

Not natively. Plandalf's beehiiv page says buyer sync is not available, so it would need your own route handler calling beehiiv's API, with consent handled.

Can a beehiiv email show a Plandalf countdown?

Yes, on an eligible beehiiv plan, through an HTML Snippet block with the snippet Plandalf generates for a promo.
