Steps
In Breww, go to Settings > Breww Apps & API to generate an API key.
Choose an access level for the key: Read only (GET/HEAD/OPTIONS only) or Full access (adds POST/PUT/PATCH/DELETE) — this is the default for new keys and applies to the entire key, with no per-endpoint scoping.
Call endpoints under the base URL https://breww.com/api/... using the documented Authorization header format from the public API reference (https://breww.com/api/schema/elements).
For read-heavy integrations (dashboards, reporting), issue a Read only key so accidental writes are rejected with a 403 rather than silently succeeding.
For integrations that must create/update records (e.g. the newer Customers & Orders write support, including order lines and adjustment lines), issue a Full access key instead.
If you get an 'endpoint not reachable' style error, check in order: whether a read-only key attempted a write, whether the Authorization header is malformed/missing its prefix, whether the base URL is exactly https://breww.com/api/..., and whether the endpoint actually exists in the public API schema.
Known gotchas
Access level is all-or-nothing per key — there is no way to grant a key write access to Orders but read-only access to everything else; use multiple keys if you need mixed scopes.
Every documented endpoint is technically reachable by any authenticated key regardless of access level; access level only gates which HTTP methods are allowed, not which endpoints are visible.
Not all Breww functionality has a public API endpoint yet — if something isn't in the published schema, it isn't accessible via API no matter the key's access level.
