Once you find and click on your competition, view the complete URL in your browser. It should have the format of:
thebluealliance.com/event/**{event_code}**
The word after the last “/” is your blue alliance code. Copy this into the app when creating a competition.
For example, let’s find the blue alliance code for the SFR 2024 Regional.
The url is: https://www.thebluealliance.com/event/2024casf
Therefore, the blue alliance code is 2024casf
