Each planned site is built as a high-fidelity "digital twin" and simulated in a sandbox before physical installation. This is a simulation/pre-deployment sandbox rather than a payments-style test-key environment. sandbox: type: simulation / digital-twin free: true purpose: >- Integrate against a sandbox and simulate future operations before committing; validate host-system integration and model site throughput. access: Provisioned with Instock during onboarding (no self-service test keys documented). docs: https://instock.com/en/docs/getting-started/ test_values: published: false note: >- Instock does not publish magic test identifiers, test cards, or fixed sandbox credentials.
