An ETag is an identifier for the content of an object. HCP generates an ETag for each object or version stored in a namespace. HCP returns the ETag for an object or version in an ETag header in the response to a GET, HEAD, or PUT request for that object or version. If HCP has not yet generated the ETag for an object or version, the ETag header is not included in the response.

You can use ETags in conditional operations. For example, you could use an If-None-Match header to store a new version of an object only if the content of that new version does not match the content of the current version.
