From August 2009 Amazon will require all REST requests to have a hash appended to url parameters of all REST requests.

Thanks a lot! I modified ecs.py version 0.3 from Kun Xi (http://kunxi.org/archives/2008/05/pyaws-030-released/) after your changes and it works. Seems that I cannot attach it here :(

Just to add, the occurrences of

for (k,v) in sortedArgv if v

should really be

for (k,v) in sortedArgv if v is not None

because *without* this tweak, values of 0 are omitted from the request, which means that removing an item from a cart by setting its quantity to 0 would fail.

Hope this helps!

Also, the timestamp is not in UTC. Instead the datetime module should be imported. Then in buildRequest there should be

argv['Timestamp'] = datetime.utcnow().strftime("%Y-%m-%dT%H:%M:%SZ")

instead of

argv['Timestamp'] = strftime("%Y-%m-%dT%H:%M:%SZ")
