Which API architectural style is used by Zscaler for Zero Trust Automation?

Zscaler Zero Trust Automation uses RESTful API architecture. REST aligns with standard HTTP methods such as GET, POST, PUT, and DELETE and is the expected API style for OneAPI and Zscaler automation workflows. Option D (REST) is correct because REST is the API architectural style used.

Why the other options are incorrect:

A. JSON-RPC: JSON-RPC is a remote procedure call style; Zscaler automation APIs are REST-style resources and methods.

B. SOAP: SOAP is an XML-based protocol with envelopes and operations; it is not the REST style used for Zscaler automation.

C. GraphQL: GraphQL lets clients query exactly shaped data through a schema; Zscaler Zero Trust Automation uses REST instead.
