Steam Donation Bot

README.md

Steam Donation Bot

A Steam bot that accepts item donations.

Basically, it accepts any offer that doesn't ask for any items from its inventory.

Feel free to use if you want to accept item donations for your project, or modify it as you see fit.

This bot does not support mobile auth as of yet.

Install and run

1. Install the latest Node.js.
2. Click 'Download ZIP' button on the top of this page.
3. Unpack this ZIP file wherever you like.
4. Switch to the resulting directory in a command line or a terminal.
5. Do npm install in the directory.
6. Edit donation_bot.js to put your account credentials. Leave authCode as is for now.
7. Run node donation_bot.js. It will 'crash' shortly, and you'll receive an email with Steam Guard code.
8. Edit donation_bot.js again to put Steam Guard code into authCode, then run node donation_bot.js again. A sentry file will be created in the same directory with the bot. From now on you can run node donation_bot.js to launch the bot.

Note: After sentry file is created, you'll need to wait for 7-15 days due to Steam Guard trade restrictions. Do NOT delete sentry file!

Mr0Inka, check your email, and paste code from email here:
var authCode = 'code here';
then save file and run again

I have almost the exact same error as Mr0Inka but have not received any emails to copy codes across. Any ideas?
Edit: Scrap that. Ran it a second time and it succeeded.

Can anyone explain here what is the use of sentry file??????

And the wait for 7-15 days are mandatory for all devices or only for new devices????

Ребят кто русские помогите!!!
P.S.

This bot does not support mobile auth as of yet.

Only email? Auth code from mobile app same as email, isn't?
