How to display array in Slack Webhook of Azure Logic Apps? - azure-logic-apps

Question

I have LogicApps. It receives property ListOfNames array in HTTP request.
I have difficulty to display correctly in Slack webhook. How to format body?
Current message displayed in Slack:
ListOfNames:
["Name1 \n","Name2\n","Name3\n"]
Target message in slack:
ListOfNames:
Name1
Name2
Name3
I tried Split:
Code: No errors, but don't array items listed correctly in message:

Answer 1

You can add a compose connector before the webhook connector and use split functionality which gives the right format and then add the output of the compose connector to your webhook connector.
Here is a screenshot for your reference:
Note: Make sure you modify the expression in your split from compose connector as split(triggerBody()?['ListOfFiles'],'\n') to split(triggerBody()?['ListOfFiles'],'\n') because when we write the expression for this, it first takes '\n' as a string and then adds another ''.
Below is the split expression in compose connector:
split(triggerBody()?['ListOfFiles'],'
')
Updated Answer
As we are retrieving an array and passing it to the body of text it is adding the extra characters to it. We have created a new Logic App and added each item that we are retrieving to a variable and finally added that variable to the Webhook body.
Here is the screenshot of the logic app
Here is my code view
