PDF response from Channel with http(s) source connector

[elemle]

My destination created a PDF attachment. Can't get this PDF to be sent as the channel response. Tried dozens of things, too many to list here, nothing works.
Found this old forum question and there was never a solution....

No code, no screenshots. No answer. You post enough here to know better.

I'd at least expect a screenshot of your source tab and response selection and how you set $r (or if you are responding from the post processor) with an attachment/attachment ID's (assuming the PDF is an attachment) base64 content assigned to a JSON object - for that matter the expected structure of your response to the caller.

Any example of returning a PDF from a mirth channel with an HTTP Listener Source Connector would be much appreciated.

(In my case the Multi-part always says No. Also do we need this to say Yes and how?) At this point I tried to return the Base64 text as the content, but I also tried to return the attached PDF too.

Not a PDF, but I suspect your problem is you have not written an http listener. The content is the easy part. That is one way of many to create responses.

I got this to work today. I have the following in a JS response transformer step of the PDF generating destination and then set the source connector return type to binary and application/pdf. I think the final piece that made it work was the ISO-8859-1 parameter.

responseMap.put('PDF', getAttachments(false).get(0).getContentString("ISO-8859-1"));
