Environments: Sandbox and Production
Two environments: Sandbox (testing) and Production (live). URLs e.g. app.sandbox.zevio.io (Sandbox) and app.zevio.io (Production). In panel header - environment switcher (Go to Sandbox / Go to Production); click opens the same section in the other environment.
Differences
In Sandbox the payment gateway runs in test mode - no real charges; you can simulate payments and webhooks. In Production payments are real. Users, organizations, offers and transactions in Sandbox and Production are separate - switching environment is a different app instance with its own data. Webhooks from Production gateway are verified; in Sandbox verification may be relaxed for testing.
