We use a Microsoft PowerAutomate Cloud Flow as our webhook receiver. After updating to Enterprise 11.3, we're trying to use signature verification to authenticate the webhook trigger.
However, since our Microsoft services are deployed in US Goverment (GCC High), we're unable to use the Encodian - Connectors | Microsoft Learn and Utlity - Create HMAC.
I'm wondering how others are generating these HMACs, using the secret key specified in the Server webhook? Or, any pointers on how to do this in Power Automate Cloud flows without using Encodian?
