Function works with POST but fails with GET request

I'm building an api that interfaces with various sms providers and allows users to send and receive texts. I'm using Flask and Python 3.4. My issue is that when I try to verify an account it works fine if I send data using a POST request. But if I use a GET request I get an error telling me to authenticate. Here is my function:

@coma_inbound.route("/twilio/verify/account",methods=["GET","POST"])
def verifyAccount():
    #pdb.set_trace()
    account_sid = request.values.get("account")
    auth_token = request.values.get("credentials")
    targetAcct = request.values.get("targetAcct")
    print(account_sid, auth_token, targetAcct)
    try:
        client = TwilioRestClient(account_sid, auth_token)
        print(client.auth)
        print("authenticated")
    except TwilioRestException as e:
        print(e)
        print("Updating Status 1")
        status = str(e.msg)[:250]
        print(status)
        return status
    try:
        print(account_sid, auth_token, targetAcct)
        print(client.auth)
        account = client.accounts.get(targetAcct)
        status = account.status
    except TwilioRestException as e:
        print(e)
        print("Updating Status 2")
        status = str(e.msg)[:250]
        print(status)
        return status   
    print(status)
    return status

My POST request is this:

curl -vvv --data "account=ACf7e45c1e1547c066005efe64f933aa45&credentials=6d76c0bab837a10e6763a61aabacf7f2&targetAcct=ACf7e45c1e1547c066005efe64f933aa45" http://127.0.0.1:5000/twilio/verify/account

Which outputs this from curl (active is expected result):

My GET request is this:

curl -vvv http://127.0.0.1:5000/twilio/verify/account?account=ACf7e45c1e1547c066005efe64f933aa45&credentials=6d76c0bab837a10e6763a61aabacf7f2&targetAcct=ACf7e45c1e1547c066005efe64f933aa45

Which outputs this to curl:

At this point it hangs until I ctrl+c then outputs this:

twilio.exceptions.TwilioException: 
Twilio could not find your account credentials. Pass them into the
TwilioRestClient constructor like this:

    client = TwilioRestClient(account='AC38135355602040856210245275870',
                              token='2flnf5tdp7so0lmfdu3d')

Or, add your credentials to your shell environment. From the terminal, run

    echo "export TWILIO_ACCOUNT_SID=AC3813535560204085626521" >> ~/.bashrc
    echo "export TWILIO_AUTH_TOKEN=2flnf5tdp7so0lmfdu3d7wod" >> ~/.bashrc

and be sure to replace the values for the Account SID and auth token with the
values from your Twilio Account at https://www.twilio.com/user/account.

Please have a look at the curl parameters. In second case you run it without double quotes - so shell parses the string. But "&" have a special meaning - run program in background. So in this case you run one script

curl -vvv http://127.0.0.1:5000/twilio/verify/account?account=ACf7e45c1e1547c066005efe64f933aa45

in background mode and another one

credentials=6d76c0bab837a10e6763a61aabacf7f2

in foreground.

As a result your python script does not get credentials and fails:

GET /twilio/verify/account?account=ACf7e45c1e1547c066005efe64f933aa45 HTTP/1.1

Quotes single or double will help.

Yours, Eugene
