Question

I’m not experienced with cURL at all, but from what I can gather, it’s equivalent to cfhttp.

I want to work with the Instagram API and authenticate a user. Their example uses cURL.

curl \-F 'client_id=CLIENT-ID' \
    -F 'client_secret=CLIENT-SECRET' \
    -F 'grant_type=authorization_code' \
    -F 'redirect_uri=YOUR-REDIRECT-URI' \
    -F 'code=CODE' \https://api.instagram.com/oauth/access_token

Would I be correct in thinking the CF version would be:

<cfhttp url="https://api.instagram.com/oauth/access_token" method="post" resolveurl="true">
    <cfhttpparam type="formField" name="client_id" value="CLIENT-ID" />
    <cfhttpparam type="formField" name="client_secret" value="CLIENT-SECRET" />
    <cfhttpparam type="formField" name="grant_type" value="authorization_code" />
    <cfhttpparam type="formField" name="redirect_uri" value="YOUR-REDIRECT-URI" />
    <cfhttpparam type="formField" name="code" value="code" />
</cfhttp>

I’m not able to try this yet as I won’t be at my development machine until a lot later, so I’m just digging around right now looking at possibilities and making pseudo-code (not tested!).

Anyone with specific experience with the Instagram API and ColdFusion who could shed some insight would be greatly appreciated.

I’m using Railo.

According to how to use cURL the -F option is form data.

http://curl.haxx.se/docs/manpage.html

So you’re going to want to send form data, not url data in your cfhttpparam tags.

<cfhttp url="https://api.instagram.com/oauth/access_token" method="post" resolveurl="true">
    <cfhttpparam type="formField" name="client_id" value="CLIENT-ID" />
    <cfhttpparam type="formField" name="client_secret" value="CLIENT-SECRET" />
    <cfhttpparam type="formField" name="grant_type" value="authorization_code" />
    <cfhttpparam type="formField" name="redirect_uri" value="YOUR-REDIRECT-URI" />
    <cfhttpparam type="formField" name="code" value="code" />
</cfhttp>

I don’t know anything about the Instagram API and only what I read in the above link about cURL so this may not be the complete solution but it looks like you’re on the right track.
