Sandbox Environment

Test keys (ss_test_…) validate read integrations against the same v1 API.

What sandbox gives you

  • Same request contract — use the same base URL, parameters, and response envelopes as production reads.
  • Same API, same filters, same response shapes — test keys call the same v1 endpoints as live keys, so integration code does not need a separate base URL.
  • Zero-credit reads — test-key entity reads return sandbox data and charge zero credits.
  • Write protection — test keys cannot mutate tags or review/data flags.
  • Production-only lookalikesPOST /v1/lookalikes rejects test keys with 400 PRODUCTION_KEY_REQUIRED and charges zero credits.

Safe to reproduce examples
Test-key reads charge zero credits. Use them to compare modes, formats, filters, and pagination before switching to production data.

Switching to production

Replace your ss_test_ key with your ss_live_ key. No code changes are needed for sandbox-supported read paths. Live keys can access lookalikes and perform production-only metadata and write operations when they include the relevant scopes.

Build with sandbox first
Sandbox keys are the safest way to validate request shape, pagination, filters, and response handling before spending production credits.

Keys are issued by our team, not a signup form. Book a 25-minute walkthrough and you'll leave with sandbox and live credentials.
