Sandbox & Testing
Prove Flows Before Go-Live
Use sandbox credentials and test cards to simulate approvals, declines, and 3DS — without touching real customer funds.
A complete rehearsal environment for payment teams
Sandbox mode mirrors production patterns with test API keys and simulated gateway behavior. Engineering validates integration logic, QA exercises edge cases, and operations confirms webhooks and dashboard visibility before live cutover.
- Sandbox API keys
- Test charge paths
- Test card scenarios
- 3DS simulation
- Dashboard sandbox visibility
How sandbox testing works
Generate test credentials
Create sandbox API keys and encryption material from your merchant account after signup.
Call test endpoints
Send charges or hosted checkout requests to test paths using sandbox credentials only.
Use test cards
Trigger success, decline, and 3DS outcomes with known test card scenarios during development.
Verify webhooks and UI
Confirm your systems receive events and that sandbox transactions appear correctly in the dashboard.
