Invoke Web Service - Zendesk

Posted on by jsteele64289

Hello All!

I'm working on a project right now that requires me to upload some files to Zendesk via API, and then attach them to a ticket later on. I can create tickets and add comments to them, with no problem, but I'm struggling to get files to upload with the method Zendesk suggests. I am starting to wonder if this action in Power Automate Desktop is not capable of doing what I need it to do, and I'm curious if others have seen the same, or if anyone has suggestions.

For reference, the attachment procedure is outlined on this page: https://developer.zendesk.com/documentation/ticketing/using-the-zendesk-api/adding-ticket-attachments-with-the-api/

They say there's the option to do it from the command line, but I am not able to get this command to work in either PowerShell or CMD:

curl "[URL of Attachment]" \ --data-binary @img_0603.png \ -H "Content-Type: application/binary" \ -v -u jdoe@example.com/token:xpfRUSj51oGQta26nhRyaLaIBdhf \ -X POST

In PowerShell, the --data-binary section doesn't work and outputs the error:

"+ --data-binary @?img_0603.png \
+ ~
Missing expression after unary operator '--'.

Any help or suggestions would be appreciated, thank you!

Hi @jsteele64289

Something appears wrong with the parameters and the syntax.

You have pasted the command from the zendesk documentation so it is not clear what is going wrong with the actual command that you are using via PAD.

Are you able to print the command you are submitting via cmd and display it into a message box and see what's wrong?

Also I hope you have taken care of other things like the one mentioned on the documentation.

If the file name contains spaces or other characters that might confuse cURL, enclose the name in quotes. If the file name doesn't have a file extension, make sure to include one in the cURL command

Hey there,

Thanks for your response. I do believe I took care of the quotes around items with spaces, and I did include the extension. The code I used in PowerShell was the same as what I pasted, so if there is an issue with syntax, please point it out to me. I got rid of the PowerShell and CMD actions, as they continually gave the error I pointed out in my original post, no matter what I did.

I will paste the code I used in Invoke Web Service below:

Also, for what it's worth, the above is the latest in a long series of revisions, and is not indicative of what I would normally try in that action.

I have attempted to use the cURL command in its entirety, in the Invoke Web Service action. I have attempted to enclose the filepath in <> "<>" " ", and I've attempted to remove extra white space within the cURL command, all to no avail so far.

Finally, I think it is worth pointing out that in all cases, a file gets uploaded to Zendesk, but the contents of said file are always a copy of whatever text I have submitted in the body of the API request. For instance, Zendesk believes a PDF has been uploaded, but when opening the PDF in notepad, the text is simply the body of the request, and the file will not open in a PDF viewer.

Okay, its hard to tell. Hope you have tried at first in Postman and it works there. Then the same values/parameters can be passed via PAD. Also this will tell whether its an issue in calling the web service or in PAD or in the parameters.

Hey there,

Yes, I tried and succeeded in Postman, but also found that PAD was not capable of sending the upload request in the Invoke Web Service action in the same way as Postman can.

This is now being achieved with calling a Python script from PowerShell, outputting the tokens from the uploads, and finally feeding those into the PAD action that creates the ticket and adds a comment with the attachment.

Let me know if knowing the code itself would be helpful at all, and I can try to post it here!

Glad to know you got to work it out in another way.

Yes you can post it here so that anyone landing on this thread having the same issue can utilise your solution.
