PEPZ

How low can I put the value on confirmationChecker before Steam starts to limit the requests?

Yeah I know about the decoy. What I've also noticed is that the real sentry file tends to be with a longer filename (atleast mine) and the "Date modified" is older. Thanks!

Does that mean I can give it a ssfn file that's located in my Steam folder?

So it would be possible to handle trade offers for multiple Steam accounts.

How about support for multiple accounts?

I'm occasionally having issues when trying to query user json formatted inventories. I'm getting 429 errors which means too many requests but what's the actual limit? What I've done to make less requests is cache the bot inventory for 3-4 minutes and cache the users inventory for 1 minute. Even then I'm greeted with 429 sometimes. I did this in PHP but as far as I know the tradeoffer-manager uses the same endpoint for inventory requests.

About the sessions, how about an internal refresher? By default it would refresh cookies for example every hour but an option for the user to set it to whatever.

Would it be possible to not have to worry about sessions expiring?
