I have tried logging in to the above mentioned website using python mechanize.

Answer 1

Ended up using requests . Turns out that I was not submitting all the details that the end-point expects. For future references anyone looking to submit any forms using POST make sure you submit all the form parameters that the end point expects. These parameters have a attribute name in their tags or You could also do Ctrl+Shift+I and look for the form parameters in the Network section.
