Using a global variable in the body of a http request in copilot studios

I'm making a http request to change a users password. I'm trying to set the password to a global variable that has been previously set within the flow.

I've tried multiple methods, listed below with the results, but nothing has worked. I have set my body to formula.

Method 1:

{

password: Global.password

}

Got a 400 for this

Method 2:

{

password: "Global.password"

}

This set the password to the variable name and not the variable value.

Method 3 (Suggested by Copilot AI):

{
  password: "{{Global.password}}"
}

Again set the password to everything within the " " and not the actual variable value.

Please use the PowerFx expression in your case:

Concatenate("{'password':", Global.password, "}")

Sorry, previous answer was for Power Automate, which you could use inside Copilot studio to do the call. If you want to do it using advanced try setting the body to raw and use the following Power FX formula

Concatenate("{'password':", Global.password, "}")

You need to insert the password using the dynamic content dialog and selecting the variable from the list. The result should look something like this. The JSON for the variable is variables('password') if password is the name of the variable.
