Splynx API in python

Hi everybody,
I did an implementation of Splynx API 1.0 in python using PHP class API.

using it for some obscure reason I always get 401 code with all http methods.
Can someone look at the python code to see what changes are needed?

BR,
Narcisse

Looks great :slight_smile:

can you try ?

  def _signature(self):
      st = "%s%s"%(self._nonce_v, self._api_key)
      hsh = hmac.new(self._api_secret.encode('utf-8'), digestmod=hashlib.sha256)
      hsh.update(st.encode('utf-8'))
      sign = hsh.hexdigest()
      return sign.upper()

please let me know about result.

ps: i’m not a python dev, so sorry for any possible errors.

lol I see my error…hmac.new(key[msg [, digest_algo]])

in place of

             hsh = hmac.new(st, self._api_secret, hashlib.sha256).hexdigest()

it should be

             hsh = hmac.new(self._api_secret, st, hashlib.sha256).hexdigest()

a big mistake!

Now is working?

Can you post lib to some repository?

For future community usage.

It works fine now…I will post my code for this.
I don’t know but for some reasons modifying an API key many times
make the key buggy…may be you can investigate this…
Even after modifying the key I got 401 error code so I finally deleted it
and create another to resolv the issue.

please check parameter nonce = and it checking on API key.

if on API key = check nonce is enable - every request increase it, and every next request nonce must be more than on request before.

https://bitbucket.org/splynx/splynx-python-api

i’m added to repo, please fork it and make pull request in case of any changes needed.

thanks.

I tested last version, it works fine. There is test python-script at Bitbucket - https://bitbucket.org/splynx/splynx-python-api/src/5313da3bddb3ae894e928e38420d5f512d4afe30/example.py?at=master&fileviewer=file-view-default

I have finally post the code on bitbucket it is the final version
