📄 Description

Closes https://github.com/better-auth/better-auth/issues/2495

This pull request improves the Stripe integration by enhancing customer creation logic and adding a new test case to ensure correct behavior. The changes focus on optimizing how Stripe customers are handled and verifying the functionality through testing.

Stripe customer creation improvements:

  • packages/stripe/src/index.ts: Updated the customer creation logic to first check for existing customers by email before creating a new Stripe customer. This prevents duplicate customer records and ensures efficient handling of customer data.

  • packages/stripe/src/index.ts: Ensured the customerId is properly updated with the Stripe customer ID after creation or lookup.

Testing enhancements:

  • packages/stripe/src/stripe.test.ts: Added a new test case to verify that Stripe.customers.create is only called once during signup and upgrade processes, ensuring the logic avoids redundant customer creation.
