However, credentials added in test mode will not be automatically replicated in live mode. You can reach out to Razorpay for basic sanity testing of the integration. Razorpay will try a test payment of a small value and ensure that the credentials are correct. ## Go Live After the integration is tested and successful, you can go live with ShopSe on Razorpay Optimizer.
