This is a very bad idea. No matter what problem you have,
a custom HTTP header is very nearly certainly the wrong solution.
For API versioning it definitely is.
Putting the version in the URI is the right approach – if in fact
you even need an explicit version. (You can always switch to
a different URI space no matter whether you made a provision for
it using a version number in the URI or not.)
Of course eBay didn’t have a lot of options, being that their API
is SOAP-centric (even though they now support non-SOAP options).
So don’t make their mistake: don’t use SOAP. If you inescapably
have to support it as an option, then at least don’t design your
API from its point of view.
