Append outputs with a comma

All,

I have this "eventid" output in an apply to each loop. I would like to combine all the event ID's and separate them with a comma.

For example: If my flow ran 4 apply to each loops my new output would show this

169652;34664;23223;45454

Hi @PowerAppsUser99

You can use join function to join elements with delimiter.

to use join you should have elements in array

So in apply for each, you can add each element to an array using append array action

and outside the loop, use join action

see the output of join action when i used ; to join elements of array ['A','B','C']

Hope this helps you !

Not related to joining the values as such - is there a reason you are using multiple Apply to each loops to get the Event IDs? Maybe you can change this to use a Select that extracts the Event IDs, then use a Join expression on the Select.

I tried appending to my string variable and I am seeing this error.

Append to string variable: outputs('HTTP_Body.1')

HTTP Join:
join(variables('Summary'),',')

This is the error

As per your other post... Assuming you want to split your string on space, then join each word with a comma.

join(split(variables('Summary'), ' '), ',')
