Hmm, I don't believe the allow only 1 subscription per customer feature expands into your usecase. You'd need to track this yourself.

If they sign up for a sub, you can store their email in your DB with the subscription ID.

and redirect them accordingly

So, you're saying that I can prevent checkout registration, when user entered (on checkout) email - I can check for it's usage somehow, before subscription would be created?

[dusk fog]

Correct

If you don't see their email in your DB, most likely they don't have a subscription (with that specific email)

How can I check it?

Is there some webhook?

[dusk fog]

When you say "checkout", are you referring to Stripe Checkout?

[abstract drum]

Yes

[dusk fog]

Ah I assumed you had your own form for this.

[abstract drum]

Oh, damn

Sorry, hard day
I forgot to mention it in initial message

My bad

[dusk fog]

Don't think you can do it with Stripe Checkout, the only option would be to have them provide their email address prior to redirecting to checkout page and then check your DB

Got it, thanks
