There this VC site which uses the BBB Api and sends over variables and checksum to BBB to join a conversation. I wanted to know how I could change the fullName property without alerting the checksum.

I've tried using Burp Suite to pause redirection to API and then switch fullName with "Test101" and then forward, but then it results in Checksum failed, which is expected.

How do I (only) change my name without the checksum failed error? Ideas?

  • this is not possible with out a new checksum, the checksum is basically for the full query string and other parameters so if you change the query string you need to create a new checksum – Nigel Savage May 25 '21 at 19:43

It is impossible to do so. I have tried a lot and couldn't make it work. You are supposed to generate a checksum exactly based on the complete URL; any minor change in the URL, would cause Checksum failure.
