According to the API documentation here, the Response header should include the etag. But when I look at the response headers, I do not see an etag, just this:
Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0
Date: Thu, 09 Mar 2017 05:51:29 GMT
Pragma: no-cache
Content-Length: 1284
Content-Type: application/json
X-Ratelimit-Remain: 598
X-Ratelimit-Limit: 600
Access-Control-Expose-Headers: Location,www-authenticate,cache-control,pragma,content-type,expires,last-modified
X-Ratelimit-Reset: 1489038864
Instead, the etag is in the JSON body. Is the documentation wrong, or am I missing something?
