Zoho Books Trigger "Bill Created" does not work

Zoho Books Trigger "Bill Created" does not work

Hello everyone,

I'm trying to set up a flow, but the trigger for Zoho Books "Bill Created" does not work.

I've been trying repeatedly to test it by creating fake bills in Zoho Books and even tough the Webhooks seems to be called through a workflow in Zoho Books, nothing happens in Flow (nothing shows up in the History tab also). I've attached some screenshots. 

Does anyone have a solution please?

Thank you!!
