Testing

NeonPay provides sandbox environments to integration partners for use during application development.

The Sandbox and Production environments are nearly identical, with a handful of minor differences. 

Testing Credit Card Charges

The sandbox environment is not capable of processing real payments. It can, however, simulate most payment scenarios encountered in production.

Successful charges can be tested by creating a token using NeonPay.JS, then submitting the charge using the NeonPay API.

A number of charge failure scenarios can be tested by sending one of the following strings as the payment token instead.

Testing ACH Charges

In sandbox environments, ACH failures can be tested by manipulating the charge amount:

Amount Result Description
500.01 Failed Exceeds Approval Amount Limit

Testing Payouts

Payouts occur automatically. The process for payouts differs slightly between sandbox and production environments. The following differences apply:

  • In sandbox, all payouts will finish with a failed status. They will never appear as processed.

Testing Fees

Fees function the same in sandbox and production environments. These are automatically applied at each fee's appropriate circumstance.

Testing Merchant Onboarding

Merchant onboarding is nearly the same in the sandbox as it is in production environments.

You can use fake data for most fields when boarding test accounts in the sandbox. The following fields do require valid data:

  • IP Address - Can be any valid IP address.
  • Routing Number - We recommend using 123123123 for testing.

Testing Disputes

It is not currently possible to simulate disputes in a sandbox environment. This is a known deficiency that our team is working to resolve.

Load Testing

The sandbox environment does not accurately simulate the performance of the production environment. As such, it is not suitable for load testing. If you plan to load test an application that relies on NeonPay, please contact the NeonPay team.

Launching to Production

The following changes will need to be made to switch your application from Sandbox to Production:

  • Update your API endpoint URLs to the Production endpoint
  • Generate new API keys in the Production merchant portal
  • Create new webhook subscriptions in the Production merchant portal
  • Update your App ID to match your Production App ID
  • Update your Public API Key to use the one generated by the Production environment
