📌 Need Help with HMAC Signature Verification in Pabbly Webhook

[OlivierFrench]

Hello,

I'm sending a form from my React website to a Pabbly Webhook and want to secure the transmission using an HMAC SHA256 signature.

Frontend: I'm generating the HMAC signature with a secret key and sending it in the "X-Signature" header.
Problem: How can I verify this signature in Pabbly before processing the data?

If anyone has implemented this verification or knows how to do it, I’d appreciate any guidance!

Thanks in advance!

Hello @OlivierFrench,

Currently, we have the feature to hash a string into HMAC SHA256 format. However, your requirement seems to have the ability to decode an HMAC SHA256-encoded key back into the normal string, you can submit your request on our Integration Request Board:
