Certificate Based Authentication HTTP action

(0) ShareShare
ReportReport
Posted on by CU29081029-2
Hello,
 
While Authenticating HTTP request based on Certificate Authentication in Power Automate , I am getting an error "Could not load the certificate private key. Please check the authentication certificate password is correct and try again."
I have uploaded the certificate (.pfx) in Azure Vault and loaded that with Get Secret Action . gave the password in the HTTP action ( the one that was used to export pfx file)
Any leads will be much appreciated

    Hi,
     
    Azure removes the password from an imported pfx when exporting it (via portal, REST-API, connector).
     
    As the HTTP action's password field is mandatory, you can use a secured parameter for it. I created a Compose action with expression "string('')", secured it and used its output for the password field.
