I'm trying to upload a file to an API using cfhttp but not having any luck. The documentation example is:

This API request must have its Content-Type set to multipart/form-data.

curl -v -u api_key:X -F 'attachments[]=@/Users/user/Desktop/api2.png' -F 'priority=2' -X PUT '<https://domain.freshservice.com/api/v2/tickets/51>'

but when I try the following,

cfhttp(url="#fsURL#",method="PUT",result="fsResult") {
    cfhttpparam(type="header",name="Authorization",value="Basic #fsAuthorization#");
    cfhttpparam(type="header",name="Content-Type",value="multipart/form-data");
    cfhttpparam(type="file",name="attachments[]",file='e:\fsApi\attachments\#childData.ticket_id#\test.jpg');
}

I get the following error:

{"message":"Invalid request parameters: invalid %-encoding (����\"#Exif\u0000\u0000II*\u0000\b\u0000\u0000\u0000\u000B\u0000\u000F\u0001\u0002\u0000\u0014\u0000\u0...\u0019\u001A%)","code":"invalid_encoding"}

If I add priority, then I don't get an error, priority does get set to 2, but the attachment never gets added:

cfhttp(url="#fsURL#",method="PUT",result="fsResult") {
    cfhttpparam(type="header",name="Authorization",value="Basic #fsAuthorization#");
    cfhttpparam(type="header",name="Content-Type",value="multipart/form-data");
    cfhttpparam(type="formfield",name="priority",value="2");  
cfhttpparam(type="file",name="attachments[]",file='e:\fsApi\attachments\#childData.ticket_id#\test.jpg');
//cfhttpparam(type="file",name="test.jpg",file='e:\fsApi\attachments\#childData.ticket_id#\test.jpg');
}

I tried the commented out line above too and still no error and no attachment.

Are you using ACF? You could try adding

multipart="yes"

to the cfhttp call. I have had issues mixing formfield and file in the same request with ACF. Maybe a bug?

I tried adding multipart="yes" and the API errors out with a a 500.

The CFHTTP tag will overwrite your content-type fields on outgoing calls. Try pointing the cfhttp call to a webhook.site url to see what is actually being sent out.

you could try this workaround to see if it works for you.

```
var NEW_LINE = chr(13) & chr(10);
var requestBody = [];
var fieldBoundary = "--------------" & getTickCount();
requestBody.append("#NEW_LINE##NEW_LINE#--#fieldBoundary##NEW_LINE#");
requestBody.append("Content-Disposition: form-data#NEW_LINE#");
requestBody.append("Content-Type: application/x-www-form-urlencoded#NEW_LINE#");
requestBody.append(NEW_LINE);
requestBody.append( "priority=2" );


requestBody.append("#NEW_LINE#--#fieldBoundary##NEW_LINE#");
requestBody.append("Content-Disposition: form-data; name=""attachments[]""; filename=""#file.getFormattedName()#.csv""#NEW_LINE#");
requestBody.append("Content-Type: text/csv#NEW_LINE#");
requestBody.append(NEW_LINE);
requestBody.append( fileRead('e:\fsApi\attachments\#childData.ticket_id#\test.jpg', "utf-8") );
requestBody.append("#NEW_LINE#--#fieldBoundary#--#NEW_LINE#");

var requestParameters = [
	{ type: "header", name: "Authorization", value: "Basic #fsAuthorization#" },
	{ type: "header", name: "Content-Type", value: "multipart/form-data; boundary=#fieldBoundary#" },
	{ type: "body", value: requestBody.toList( "" ) }
];

cfhttp(
	method=fsMethod,
	charset="utf-8",
	url=fsURL,
	result="httpResponse"
) {
	for ( var httpParameter in httpParameters ) {
		cfhttpparam( attributeCollection = httpParameter  );
	}
}
```

I set up an endpoint that I could send this to and dumped the GetHttpRequestData() but the content is just binary. Is there a better way to capture the request?

You could try something like this.

content = isBinary(gethttprequestdata().content ) ? CharsetEncode(gethttprequestdata().content, "UTF-8") : gethttprequestdata().content ;
writeOutput("<pre>#content#</pre>");abort;

This is with the code I originally posted:

I would try it with the curl command and see what that looks like.

I'm not familiar with curl, but I tried it and am getting access denied. It doesn't seem to like my authorization. {"code":"access_denied","message":"You are not authorized to perform this action."}

I meant to hit your dummy endpoint to just see what the raw request looks like.

I captured the request from curl so I'll see if I can adapt your code to the structure curl sent.

No problem. In my case it was a csv. You would need to change this bit for a binary image.

requestBody.append("Content-Type: text/csv#NEW_LINE#");
requestBody.append(NEW_LINE);
requestBody.append( fileRead('e:\fsApi\attachments\#childData.ticket_id#\test.jpg', "utf-8") );

yeah, I did that.

Makes me wonder if there is some whitespace character throwing it off.

hmm, no matter what I upload through the API, the service has the content-type as "application/octet-stream":

Can you make the call work with a tool like Postman? I'd try working with that first, then reverse engineering it from there. That way you can quickly iterate tests and see what is being sent back and forth. Also, if you can't get it to work with Postman, you at least have some ammo to go back to the API vendor and ask them to help get it working there...

Good idea. I found an article where someone created the request using PHP. They also have an example for Postman that I tried to follow. Verified I have basic functionality getting simple requests to work with Postman but trying to upload attachments with that doesn't seem to work either. I just get a response back with an error:

{
  "message": "Invalid request parameters: invalid %-encoding ('' id='W5M0MpC...) , #)",
  "code": "invalid_encoding"
}

Not encouraging. I'm reaching out to Freshservice to see what they have to say.
