According to your documentation, it states that:

> “During migration, both headers are sent with each webhook.”

However, in our actual webhook requests, we only receive **one signature header** :  
Fireblocks-Signature.  
I have tested and observed this behavior for both **v1 and v2 webhook payloads** , but I do **not** see two separate signature headers being sent simultaneously as described in the documentation.

Could you please help.

Thank you for your assistance.

The same situation. But I’m getting no any headers related with signature.
