# Validate & Deploy

## Get Ready to Run!

Once you have completed your integration, we will provide a set of validation transactions to complete prior to issuing your production credentials. Please reach out to your Integration Delivery lead to request the most recent validation test suite and to complete this validation step.

### Sample Validation Tests

You may use any numbers for the CVV when using these test cards. The highlighted cells must be filled out from the response data and returned to your Integration Lead to confirm the completion of the validation step.

## UAT Response Codes

When testing in UAT, you can trigger specific decline scenarios by charging a particular amount (in cents) against a brand-specific test card. Each amount maps to a specific association response code and description.

See the full reference in the [Test Cards](/docs/guides/payments/test-cards) guide — covering AMEX, Discover, Mastercard, and Visa.

## Next Steps

With your integration built, tested, and deployed, you are ready to run payments! Explore the other features of Run Developer to extend your payments capabilities including accepting ACH payments and storing card-on-file records.
