ETag support
The business entity schema endpoints support the use of ETags. An
ETag
response header is returned with every request. The ETag acts
as a checksum of schema content, so it changes depending on which query parameters you
use.
Use the ETag with the If-None-Match
request header. If this
matches the current checksum, you’ll receive a “304 not modified” response. If it
doesn’t match, the request will be processed normally.
ETag is a standard HTTP header. More information can be found by doing an internet search.
