# Environments

> Separate sandbox development from regulated production use.

Heyrafiki keys are bound to one environment.

| Environment | Key prefix | Purpose                                                         |
| ----------- | ---------- | --------------------------------------------------------------- |
| Sandbox     | `sk_test_` | Synthetic data, integration development and conformance testing |
| Production  | `sk_live_` | Approved live workloads                                         |

Sandbox and production do not share keys or data. A key for one environment is rejected in the other.

## Safe development

* Keep keys in server-side secret storage.
* Use one project per integration and environment.
* Request only the scopes the integration needs.
* Revoke a key when it is exposed or no longer used.
* Never copy live health data into the sandbox.

Production access is staged. A documented production resource may still require project-specific approval.
