How to pass parameter to runbook using HTTP Post?

(0) ShareShare

Posted on by 105

I was having problems passing some variables in a powershell script/runbook/webhook via a post http call so I thought I would find a much simpler script and try, but its still the same so I’m obviously doing something wrong. Here is the powershell script/runbook which I’m calling via a webook:

 

 

 

 

 

 

 

Param
(
 [Parameter (Mandatory= $true)]
 [String] $Name
)

## Hello 
write "Hello $Name"

 

 

 

 

 

 

 

This is my basic flow

I just cant seem to wrap my head around the formatting that is required and I've tried to many variations that I'm starting to get lost. Here are a few other screenshots that might be useful:

Since the script has " [Parameter (Mandatory= $true)] [String] $Name" it prompts you to enter a:

"default value which would be used if no specific value is entered instead".

during the creation of the Webhook, I tried removing this as well but then it just says "Hello" and still ignores any value I put in my PA flow.

 

I must be doing something so stupid but if I can get this simple example working I can implement the same formatting over to my more complicated (well complicated for me) project and continue working away.

 

Thanks for any help or advice.
