Is this suited for github?

  • Yes, this is suited for github

To Reproduce

When using Better Auth with Stripe, the referenceId (defaulting to user ID) is marked unique in the DB. This causes problems when a user cancels a subscription immediately and tries to resubscribe to the same plan.

  1. User subscribes to a plan (e.g., "Starter") — subscription stored in DB with referenceId = user.id.
  2. User cancels subscription immediately in Stripe portal.
  3. DB record still exists with status = canceled.
  4. User tries to subscribe to the same plan again.
  5. Server throws duplicate key error due to unique constraint on referenceId.

Current vs. Expected behavior

  1. Users should be able to resubscribe to the same plan after canceling.

What version of Better Auth are you using?

Additional context

referenceId is currently unique across all subscriptions, not just active/trialing ones.
Better Auth docs mention that only one active or trialing subscription per reference ID is allowed, but the unique DB constraint may be too strict, blocking canceled subscriptions.

subscriptionSchema.index({ referenceId: 1 }, { unique: true });
subscriptionSchema.index({ plan: 1 });
subscriptionSchema.index({ status: 1 });

@dosubot[bot] commented on GitHub (Nov 5, 2025):

The unique constraint on referenceId in the Better Auth Stripe plugin applies to all subscriptions, regardless of status. This means that when a user cancels a subscription, the canceled record still blocks any new subscription with the same referenceId, causing the duplicate key error you’re seeing. This is stricter than the intended business logic, which is to allow only one active or trialing subscription per user but permit resubscription after cancellation.

There’s currently no built-in config or hook in Better Auth v1.3.34 to scope the uniqueness constraint to only active/trialing subscriptions. To achieve the behavior you want (1 user = 1 active subscription, but allow resubscription after cancel), you have a few options:

  • Change the unique index in your database to a compound or partial index, such as { referenceId: 1, status: 1 } and enforce uniqueness only for active/trialing statuses. This aligns the DB constraint with the business logic, but requires a migration and may depend on your DB’s support for partial indexes (MongoDB supports this with a partialFilterExpression).
  • As a workaround, manually delete or archive canceled/incomplete subscriptions in your DB to unblock resubscription, but be aware this can affect your audit/history.
  • If you need to keep all records, enforce the “only one active/trialing subscription per user” rule at the application level, not with a DB unique constraint.

This is a known issue and has been discussed in several threads (example, example). There is no official fix in the core package yet, so any solution will require a schema change or custom logic in your project. Be careful with migrations and test thoroughly to avoid allowing multiple active subscriptions per user.

@bytaesu commented on GitHub (Nov 7, 2025):

Would you like to try subscription.restore? If referenceId were unique, you would get a database error when resubscribing after a subscription is completely ended. Therefore, I believe there is no issue with this part. If you continue to experience specific problems, please leave a comment! 🙂
