HI gurus

Very new to Python and therefore to all this so go easy on me, I am trying to just login to logicMonitor using python 3

I have my accesskey and all that good stuff, well I think do, but I cant seemed to be able to login into my account.

I have :

signature = base64.b64encode(hmac.new(AccessKey,msg=requestVars,digestmod=hashlib.sha256).hexdigest())

But i get the expected a "byte" and got str instead.

can someone share their Python code to just login into logicmonitor , so I can learn on how to do it and what am I doing wrong?

Thanks a bunch

With the API, you log in for each and every call.

You might consider using the SDK, instructions here. My personal wrapper to streamline the sdk is described a href="https://communities.logicmonitor.com/topic/7713-lm-wrapper-for-the-python-sdk/#comment-86637" rel="">here.

Here's my LM_GET function, don't remember where I got it.
