Sandbox Endpoint

Overview

A Sandbox Endpoint is a non-production API or RPC address intended for integration testing. It differs from a mock endpoint because the provider may operate a complete test backend with state, limits, callbacks, and validation behavior.

The main risks include sending production data to test systems, using sandbox URLs in live mode, missing features, unrealistic timing, and environment-specific bugs. It accepts sandbox credentials and returns test or simulated outcomes according to the provider environment.

In production, teams should define ownership and apply explicit hostname, TLS validation, separate credentials, environment configuration, callback isolation, data cleanup, and parity documentation. Scenario data for Sandbox Endpoint should be repeatable, isolated, and safe to reset without affecting live customers or balances.

Useful measures include sandbox availability, test request success rate, parity defects, configuration drift, and accidental cross-environment calls. Sandbox Endpoint is closely connected to Sandbox Account, Mock Server, and Live Mode. Test data, credentials, endpoints, and callbacks used for Sandbox Endpoint should remain clearly separated from production resources.

The Sandbox Endpoint evidence should retain environment, scenario, version, request and event IDs, observed result, and reviewer decision. The Sandbox Endpoint environment should state which production behaviors are simulated, which are omitted, and which results require later live validation.

A successful Sandbox Endpoint scenario should verify final application state rather than only a mocked response or transport status. Failure coverage for Sandbox Endpoint should include invalid input, timeout, duplicate delivery, partial processing, and recovery where the interface supports them. The Sandbox Endpoint plan should include expected results and assertions for both technical responses and the resulting application state.
