I'm trying to trigger a Power Automate flow via an HTTP Callout action in my SF flow, but am not having any luck. I have the 'When an HTTP request is received' trigger setup in PA, giving me the HTTP URL to POST to, but I'm not having any luck connecting in the 'Connect for Schema' portion during the external service configuration. I'm pretty sure the issue is with the Named/External Credentials, but I can't seem to find the right configuration needed to successfully authenticate to Microsoft/Power Automate. Normally I trigger PA off of a record update, but it doesn't have the flexibility of triggering only when a particular field is changed on a record like SF does. I tried triggering PA from via a Platform Event, which I'm then able to set as my object to trigger from in PA, but it for some reason never triggers the flow to run. Has anyone had any luck with doing something similar? Thanks!!
Sorry, I haven't had to do much with External Services and HTTP Callouts in Flow.
This Trailhead goes through a process to register an External Service.
