Getting SendGrid API Keys to work with ColdFusion

Question

I'm having issues getting my ColdFusion application to integrate with Sendgrid's v2 API using API Keys. My solution has worked for years using username/password, but with the switch over to API Keys, something is amiss that I cannot figure out. I've tried a few different configs, but none have worked thus far:

<cfhttp method="POST" url="https://sendgrid.com/api/mail.send.json?api_user=apikey&api_key=[my key]" resolveurl="no" timeout="60" result="mailSent">
<cfhttpparam type="formField" name="to" value="to@email.com">
<cfhttpparam type="formField" name="from" value="from@email.com">
<cfhttpparam type="formField" name="fromname" value="Test User">
<cfhttpparam type="formField" name="subject" value="Test Send">
<cfhttpparam type="formField" name="text" value="This is a test">
</cfhttp>

<cfhttp method="POST" url="https://sendgrid.com/api/mail.send.json" resolveurl="no" timeout="60" result="mailSent">
<cfhttpparam type="formField" name="to" value="to@email.com">
<cfhttpparam type="formField" name="from" value="from@email.com">
<cfhttpparam type="formField" name="fromname" value="Test User">
<cfhttpparam type="formField" name="subject" value="Test Send">
<cfhttpparam type="formField" name="text" value="This is a test">
<cfhttpparam type="formField" name="api_user" value="apikey">
<cfhttpparam type="formField" name="api_key" value="[my key]">
</cfhttp>

<cfhttp method="POST" url="https://sendgrid.com/api/mail.send.json" resolveurl="no" timeout="60" result="mailSent">
<cfhttpparam type="formField" name="to" value="to@email.com">
<cfhttpparam type="formField" name="from" value="from@email.com">
<cfhttpparam type="formField" name="fromname" value="Test User">
<cfhttpparam type="formField" name="subject" value="Test Send">
<cfhttpparam type="formField" name="text" value="This is a test">
<cfhttpparam type="header" name="api_user" value="apikey">
<cfhttpparam type="header" name="api_key" value="[my key]">
</cfhttp>

<cfhttp method="POST" url="https://sendgrid.com/api/mail.send.json" resolveurl="no" timeout="60" result="mailSent">
<cfhttpparam type="formField" name="to" value="to@email.com">
<cfhttpparam type="formField" name="from" value="from@email.com">
<cfhttpparam type="formField" name="fromname" value="Test User">
<cfhttpparam type="formField" name="subject" value="Test Send">
<cfhttpparam type="formField" name="text" value="This is a test">
<cfhttpparam type="cgi" name="api_user" value="apikey">
<cfhttpparam type="cgi" name="api_key" value="[my key]">
</cfhttp>

Help?

I think I figured it out. After poking around in this codebase:

https://github.com/mjclemente/sendgrid.cfc/blob/master/sendgrid.cfc

...it looks like the syntax needs to be:

<cfhttp method="POST" url="https://sendgrid.com/api/mail.send.json" resolveurl="no" timeout="60" result="mailSent">
<cfhttpparam type="formField" name="to" value="to@email.com">
<cfhttpparam type="formField" name="from" value="from@email.com">
<cfhttpparam type="formField" name="fromname" value="Test User">
<cfhttpparam type="formField" name="subject" value="Test Send">
<cfhttpparam type="formField" name="text" value="This is a test">
<cfhttpparam type="header" name="Authorization" value="Bearer [my key]">
</cfhttp>
