@Robert Heynen Thanks for reaching out. If you can share the schema or the response data (removing the sensitive information in your HTTP trigger output) then I can assist you with how you can access that property in your workflow. You can also refer to this document on how to create your workflow based on your alert.
How can I access Azure Alert Custom Properties in a Logic App
In the standard Common Alert schema, there is a "CustomProperties" object that holds an array of Key Value pairs (I am assuming this references the Custom Properties of the Alert"
How can I access the values from inside a Logic App that is sending an email?
I have tried expression variable('keyname')[0] but that will not allow me to save without instantiating the variable
Ultimately I am hoping to store the emailTo and emailCC in those fields so I can easily change them if needed. We have multiple clients that I want to send an alert to but need some flexibility as to who I can send it to
