You will need to get your SWID and ESPN_S2 values to utilize the bot in order to access all of the necessary data.
You can use this chrome extension to more easily get the information after navigating to your league page. (Source code for this extension can be found here for inspection, if curious.)
Alternatively, you can get this information manually. You can find these two values after logging into your ESPN fantasy football account on ESPN’s website. (Chrome Browser) Right click anywhere on the website and click inspect option. From there click Application on the top bar. On the left under Storage section click Cookies then http://fantasy.espn.com. From there you should be able to find your SWID and ESPN_S2 variables and values.
