Simulate Authorizations and Declines
Warning: The Highnote test environment allows you to explore the platform features and functionality freely. It is intended for experimenting, building integrations, and training your team.
To ensure the security of your real-world data, please do not enter production data in the test environment. Production data includes sensitive information like customer details, financial data, or personally identifiable information (PII).
Use only dummy or test data explicitly created for testing purposes in the test environment.
To test your payments integration, you can use test Primary Account Numbers (PANs), addresses, and CVCs to simulate various scenarios, including specific card brands, error code responses, and successful payments.
We currently support simulation card data for the following brands:
| Card Network | PAN | CVV/CVC | Expiration | Address |
|---|---|---|---|---|
| Visa | 4000 0000 0000 0000 | 111 | Any future date | 1234 Visa St, Visa, CA 12345 |
To simulate a successful authorization, use the following inputs in your payment form:
- A valid simulation PAN
- A valid simulation CVC
- Any valid future expiration date
- A valid simulation billing address
Use the corresponding simulation values of the card network of your choosing for each of the required inputs by referencing the simulation card data table above.
The following transaction amounts will generate specific decline codes for cards. Set the desired card network using the simulation card data listed above:
