Headers
string
enum
Defaults to 2.0

Selects the RAP API version for this request. New integrations should pin 2.1 (identical to 2.0 today; future refinements land there). Omit to use the base version (2.0). A value naming an unsupported version — including an empty value — returns HTTP 400; if the header is sent, it must name a supported version. See the API description for the full version policy.
