# Variable: STOREFRONT\_ENVIRONMENTS\_CASCADE

> `const` **STOREFRONT\_ENVIRONMENTS\_CASCADE**: `ScopeCascade`

Defined in: [packages/b2c-tooling-sdk/src/clients/storefront-environments.ts:85](https://github.com/SalesforceCommerceCloud/b2c-developer-tooling/blob/36eea0d308f1312d1a446ec8813ed30b0bdba62c/packages/b2c-tooling-sdk/src/clients/storefront-environments.ts#L85)

Per-operation scope cascade for the SCAPI Storefront Environments API.

Reads accept either rw or ro; writes require rw. The auth middleware tries
each candidate against AM in order, caches the first that survives, and lets
a broader cached token satisfy a later narrower request without an extra
round trip.
