Test mode API keys
Develop against a parallel sandbox dataset without touching production.
Issue sv_test_* keys from Settings → Developers (Mode radio above the Generate button). Test-mode calls operate on a completely separate dataset — properties, site visits, action items you create with a test key never appear under a live key, and vice versa.
Test mode is free and unmetered. Test resources don't count against your free-plan property or visit limits, so developers on any tier can build end-to-end without paying.
Webhook endpoints can also be created in test mode — those only receive events from sv_test_* traffic. Payloads include livemode: false so receivers can branch without parsing the resource.
