## Best Practices

Before routing all traffic or some traffic to a new gateway via Optimizer, the following best practices are recommended:

### Live and Test Mode Rules

All rules configured in live or test mode on the Razorpay Dashboard will reflect in live mode. However, credentials added in test mode will not be automatically replicated in live mode.

### Sanity Test at Razorpay

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.
