Prerequisites
- Concept Trusted Network Zones **Trusted Network Zones** is a security concept used to prevent redirection attacks by defining a list of trusted hosts or network zones. Developers and administrators use it to maintain a [protection allowlist](https://help.sap.com/docs/btp/sap-business-technology-platform/81aed02afbdb41379fe0eb4b23f7756a?locale=en-US&state=PRODUCTION&version=Cloud) of approved hosts, helping to guard against threats such as clickjacking. The [Trusted Network Zones entity](https://help.sap.com/docs/btp/sap-business-technology-platform/e544675d9a4a4e98b00f94118b45325d?locale=en-US&state=PRODUCTION&version=Cloud) exposes properties that can be read and managed programmatically via integration services, enabling automated maintenance of these allowlists.
- Concept OAuth2 Client Credentials Grant Flow The provided sources do not contain sufficient information to define a specific, identifiable SAP developer concept — the concept name is listed as "undefined" and the source snippets cover a broad range of unrelated topics (OAuth2 Proxy, JWT security, API calls, service instances, and various tutorials) without converging on a single definable concept. A meaningful, source-grounded definition cannot be produced.
