Can not change 'configure callback handler url' on fireblocks sandbox

[nathan]

I’m working on the Sandbox with the cosigner feature. Initially, I configured the callback handler URL using a temporary ngrok domain. After restarting my local machine, the domain changed, but I realized the Sandbox only allows setting the callback handler once. I can not change ‘CONFIGURE CALLBACK HANDLER’ to other url.

How can I change ‘CONFIGURE CALLBACK HANDLER URL’?

Hi @nathan ,

Please consider submitting a support ticket with us to configure/update the callback handler URL for Fireblocks CCMT.

Thanks!
