LAS:eR API Authentication

From ianibbo:
In case it's useful for devs on the issue - this is how I'm testing the auth:

#!/bin/bash
secret="YOURSECRET"
token="YOURTOKEN"
host="https://laser-qa.hbz-nrw.de"
path="/api/v0/subscriptionList"
timestamp=""
nonce=""
q="globalUID&v=1"
auth=`echo -n "GET$path$timestamp$nonce$q" | openssl dgst -sha256 -hmac "$secret" | awk '

Unknown macro: {print $2}

'`
echo sending curl $host$path?$q -H "x-authorization: hmac $token:::$auth,hmac-sha256"
curl $host$path?$q -H "x-authorization: hmac $token:::$auth,hmac-sha256"
