## Deprecated header + Sunset
If you are calling some endpoint in a version that will not be supported in
the future, you will receive a response with the header
`X-Shoptet-Deprecated`. If you detect this header within the response and
its presence is logged,
you should be aware of the support termination for a specific endpoint in
advance and thus have enough time for correction.
Furthermore, you shall also receive the response with a`Sunset` header with
the date when the support for this endpoint is to be terminated.
