The sandbox uses the same base domain as production, with/api-test/ instead of /api/ in the path:
Example
Authentication in Sandbox
Authentication works identically to production — you still need a valid mTLS client certificate and a Bearer token obtained from the OAuth endpoint. Sandbox and production share the same auth flow.Getting Sandbox Credentials
Sandbox credentials are separate from production credentials. Contact your Clara integration team to request access:What You Can Test
The sandbox supports the same endpoints as production. You can test:- Card creation, configuration, lock/unlock, and deletion
- Transaction retrieval with filters and pagination
- User management
- Billing statement retrieval
- VCN lifecycle (create, update, cancel)
Differences from Production
Sandbox data is periodically reset. Do not build long-running dependencies on sandbox UUIDs or state — treat each test session as ephemeral.
