    Hi Smiley

    Please write a script to use the following FIX API endpoint: https://docs.gdax.com/#fix-api
    Compatible to python 3.4.2 version!
    I'm paying you 0.03 BTC , but at least 100€ and at max 150€ (in case BTC price changes)

    I don't like module style with several scripts and an init script (no install of of module, just import from same folder) So I just want 1 single script, that I can import.
    If REST API calls are needed (don't know if so), please use the requests modul. The script should fully handle the FIX connection. I would like to have one function for each method described in API documentation.
    You do not have to write a FIX script, I think you can use "PyFIX" module for that: https://github.com/wannabegeek/PyFIX
    Don't forget SSL-Tunnels, I don't know if this is included in PyFIX? Please add error handling for all FIX related errors (eg. connection aborted/reconnect).
    You dont have to analyze the response from GDAX. I will myself see what it includes and handle it according my needs.

    Please also include a small "how to use".
    I'm familiar with REST and websocket API, but have no clue what FIX API is and how it works. Since you can use the PyFIX module, I think a small budget is enough.

    In case you already know an open source project that is already for GDAX FIX and compatible to python 3.4.2 please tell me. I will pay 0.005 BTC in this case.

    If you need to test private calls, you need yourself an account at GDAX and create API Key, since I can not give you my API key to test. Even with sandbox API keys you can see my account details and of course I don't want that Cheesy Or you can present me your solution and I will test private connection.

    Is this what you needed

    It doesn't support FIX API currently

    Hi there,

    Was a solution for this ever reached? I can't get the logon message to work, I'm sending this from Python 3.5:

    b'8=FIX.4.2\x019=170\x0135=A\x0134=1\x0152=20171105-14:04:23.536\x0149=f3e85389ffb809650c367d42b37e0a80\x0156=Coinbase\x0198=0\x01108=30\x01554=password\x0195=44\x0196=g2xSF8vPFYVuP4cpiVgM+E+B1cvzwoSFhzbUQFC6FQ4=\x018013=Y\x0110=238\x01'

    (The password bit is my actual password in reality). Can anyone advise on what to do to make it work? Willing to pay for help getting it to work.

    JP

    I'm also looking to collaborate on this project and I have some funds to throw around.

    I am using PyFIX and I have full connectivity up to the login phase.  No matter what I do I'm unable to get a successful login.  Here is the code i'm currently using to generating my login message.  Everything looks good on the wire.

    Code:
        def logon():
            timestamp = datetime.utcnow().strftime("%Y%m%d-%H:%M:%S.%f")[:-3]
            # pseudo code for message because the blog won't let me paste the actual char command, replace chr1 with chr function and send it a 1
            message = timestamp + chr1 + 'A' + chr1 + '1' + chr1 + 'api_key' + chr1 + 'Coinbase' + chr1 + 'passphrase'
            hmac_key = base64.b64decode('api_secret_key')
            signature = hmac.new(hmac_key, message, hashlib.sha256)
            signature_b64 = signature.digest().encode('base64').rstrip('\n')
            msg = FIXMessage(msgtype.LOGON)
            msg.setField(fixtags.Password, 'passphrase')
            msg.setField(fixtags.RawData, signature_b64)
            msg.setField(fixtags.EncryptMethod, 0)
            msg.setField(fixtags.HeartBtInt, 30)

    The message I'm getting back from the server is saying that there's something wrong with the signature and the specific failure id is MsgType=3, SessionRejectReason=5 which translates to "Value is incorrect (out of range) for this tag".

    Thanks for the help!
