Hi,
My Sandbox Webhook Worked for months but recently encountered “Invalid webhook signature”…
Are there any changes to the public key for sandbox recently?
Here is my sandbox account: devenvs@myunbox.com
Please advise.
Many thanks!

I am also facing this issue in my sandbox account

Same here, public key for the sandbox environment simply does not work for validation with crypto.createVerify(‘RSA-SHA512’).

I have tried to modify the key adding/replacing line jump characters, but alas nothing is working, not even the example code. The same code works perfectly on production I must add.

Has been a new change made to the sandbox public key that is not reflected on the documentation?

Please let us know, thank you!.

I’m trying a brand new Webhook integration with Fireblocks. I thought I was doing something wrong, but I’m also seeing this error. I used the public key found on this page: https://developers.fireblocks.com/reference/verify-requests. Is the documention out of date?
