Redeem Hoyo Codes Automatically

Don't want to miss out on free stuff but too lazy to do it by hand? This is what this script helps to solve. Works for Genshin, Honkai: Star Rail, and Zenless Zone Zero.

Google Apps Script

1. Create a Google Apps Script and copy the code from Code.gs into it. Then for each account and game do steps 2 to 7 to setup your account info.

2. Open a redeem code page in your browser.

3. Login to your account.

4. Open the developer menu by hitting F12 and go to the network tab.

5. Enter anything in the code and click the button. A request should appear.

6. Click on the GET webExchangeCdkey request., and copy over to the right game URL in the script the region, game_biz and uid parameters. -- or directly copy the URL and you'll replace that, at your own risk if there are more parameters (it needs lang to work too).

7. Then, scroll down into the Request Headers section and copy the part of the cookie that includes cookie_token_v2, account_mid_v2 and account_id_v2.

8. In the Google apps script, on the left sidebar go into "Project Settings", and in the bottom add/edit a property named COOKIE and paste what you just copied in and click save. If you have multiple accounts, you can save different cookies by providing a property per account you are using. For example if you named your profiles "main" and "2nd", you can provide the properties "COOKIE_main" and "COOKIE_2nd" to have the script use these for the configured profile.

9. Set DISCORD_ID and WEBHOOK_URL properties also, so that it notifies you when it uses a new code or when you need to copy a new cookie. If you don't want to be pinged, leave DISCORD_ID blank.

Running:

First, run it by choosing first_main in the top bar and running. Then, you will to set a trigger for it to run periodically.

In the left sidebar, go to "Triggers", then click "Add Trigger". The function to run should be main, and I recommend to make the source Time-driven, triggering at Day timer and a random time of day. Then click save and it's finished.

NEVER CLICK LOG OUT ON HOYOVERSE WEBSITE.

If it ever says you are not logged in, just repeat steps 5 to 8.
