Cfhttp call to send multiple files

Trying a api to post message and it is working fine:
<cfhttp result="httpResponse" method="post" url="#request.api#Message/post" timeout="30">
	<cfhttpparam type="header" name="authorization" value="Basic #ToBase64("#request.username#:#request.password#")#" />

	<cfhttpparam type="formfield" name="toEmail" value="#toEmail#"/>
	<cfhttpparam type="formfield" name="subject" value="#subject#"/>
	<cfhttpparam type="formfield" name="message" value="#message#"/>
	<cfhttpparam type="formfield" name="attachment[]" value=""/>

Question is this how can I send multiple files as an array attachment[] through Lucee?

response without attachments

    "status": true,
    "message": "Message sent successfully",
    "data": {
        "id": 324

This thing is achieved in JavaScript but need to do in Lucee., index){
    formData.append('attachment[]', val.file)

Don’t forget to tell us about your stack!

you need to use <cfhttpparam type="file"> to send files?

Thanks for the reply.
Yes, this is to send single file by specifying file path.
What if need to send multiple files.

well, you need to experiment yourself!

look at what the javascript post looks like in dev tools

then run chttp thru a local proxy like fiddler and compare the results

Sure. Thank you! :]
