Kraken API 'EAPI:Invalid key' with Python3

Trouble importing module in Python

QUESTION

Kraken API 'EAPI:Invalid key' with Python3

Asked 2019-Feb-25 at 23:49

I tried making a simple function which makes a HTTP request to Kraken exchange API. The method is private, I am trying to fetch my account balance.

According to Kraken documentation (https://www.kraken.com/features/api#general-usage):

HTTP header:

API-Key = API key

API-Sign = Message signature using HMAC-SHA512 of (URI path + SHA256(nonce + POST data)) and base64 decoded secret API key

POST data:

nonce = always increasing unsigned 64 bit integer

otp = two-factor password (if two-factor enabled, otherwise not required)

I tried to make my signature generation similar to the "veox" Python library (available at: https://github.com/veox/python3-krakenex/blob/master/krakenex/api.py).

I am using Python 3.6.7 on Ubuntu 18.04.

2FA (otp) is turned on for my account on Kraken exchange, though I am not sure if I need to include in the request.

I searched stack overflow for the solution, but I can't seem to get anything from the posts available. (Please keep in mind I'm fairly new to Python and Stack Overflow)

I get 200 response from the server so I am pretty sure the problem is in generating the signature.

Here is my code (xxx, yyy and zzz variables are purposefully written like that):

So I figured out why my code was not working.

Short answer:

POST data used in the Kraken API call has to be URL encoded. That means that "nonce" and "otp" have to be URL encoded for the API to work properly. I used "urllib.parse.urlencode" method from the "urllib" module to get API to work properly.
Header values have to explicitly be called the same names as in the Kraken API manual.

Long answer:

This may be because I am a beginner in coding API's, but Kraken API manual does not explicitly state that POST data has to be URL encoded. OTP (2 factor authentication) did not affect my code in this case so I got rid of that part of the POST data in the call.

In my case, the only POST data I used was the "nonce" value. So for example, if in the above code nonce was equal to

QUESTION

Trouble importing module in Python

Asked 2017-Jul-30 at 21:44

Versions

OS: OSX Sierra Python: 3.5

What am I trying to achieve?

I'm trying to import krakenex and run it with cmd + b in Sublime Text 3 on OSX.

What do I expect to happen?

I expect to be able to run the example open-positions.py (or any other).

What happens instead?

When pressing cmd + b, I get
"import krakenex ImportError: No module named krakenex"

If I create a new file that just says "print 'hello world'" and then press cmd + b, it does print 'hello world'.

However, krakenex is not imported when I press cmd + b within open-positions.py.

The problem is probably very basic. I learned python the day before yesterday, installed Anaconda yesterday, and I have very little experience with APIs. Apologies for the incompetence.

I downloaded the zip file from https://github.com/veox/python3-krakenex/, extracted it, then ran python3 setup.py install within that extracted directory. I then opened that whole extracted folder with Sublime Text 3. Then, within open-positions.py, if I press cmd + b, I get said error message.

The full output is

raceback (most recent call last): File "/Users/Norbert/Downloads/python3-krakenex-master/examples/open-positions.py", line 1, in import krakenex ImportError: No module named krakenex [Finished in 0.1s with exit code 1] [shell_cmd: "python" -u "/Users/Norbert/Downloads/python3-krakenex-master/examples/open-positions.py"] [dir: /Users/Norbert/Downloads/python3-krakenex-master/examples] [path: /usr/bin:/bin:/usr/sbin:/sbin]

Much appreciated.

Here is your problem. See, your program is written in Python 2. Had you run it in Python 3, it would say SyntaxError: Missing parentheses in call to 'print'.

You've installed that module into your python3 and are running python2 from ST3.
