Nexmo API & CFHttp POST

Question

I am trying to use CFHttp to POST to the Nexmo API.

API documentation

<cfhttp url="https://rest.nexmo.com/number/buy/" method="post">
    <cfhttpparam name="api_key" value="#api.key#" type="url">
    <cfhttpparam name="api_secret" value="#api.secret#" type="url">
    <cfhttpparam name="country" value="US" type="url">
    <cfhttpparam name="msisdn" value="11234567890" type="url">
</cfhttp>

I get a status 420 (wrong parameters) when running this.

What am I doing wrong?

Here is an example in PHP: API

Answer 1

Looking at the API documentation it appears to me that they are expecting the fields to be form values. Here is an excerpt from the documentation here:

HTTP Methods

All requests are submitted through the HTTP POST or GET method using UTF-8 encoding and URL encoded values.

Expected "Content-Type" for POST is "application/x-www-form-urlencoded", however we also support "application/json", "application/jsonrequest", "application/x-javascript", "text/json", "text/javascript", "text/x-javascript", "text/x-json" when posting parameters as a JSON object.

So try changing your code to the following:

<cfhttp url="https://rest.nexmo.com/number/buy/" method="post" charset="utf-8">
    <cfhttpparam name="Content-Type" value="application/x-www-form-urlencoded" type="header">
    <cfhttpparam name="Accept" value="application/xml" type="header">
    <cfhttpparam name="api_key" value="#api.key#" type="formField">
    <cfhttpparam name="api_secret" value="#api.secret#" type="formField">
    <cfhttpparam name="country" value="US" type="formField">
    <cfhttpparam name="msisdn" value="11234567890" type="formField">
</cfhttp>

Note that I have the Accept header set to application/xml. According to the docs this could also be application/json. Change that value depending on what you want.

Try changing to formfield

<cfhttp url="https://rest.nexmo.com/number/buy/" method="post">
    <cfhttpparam name="api_key" value="#api.key#" type="FormField">
    <cfhttpparam name="api_secret" value="#api.secret#" type="FormField">
    <cfhttpparam name="country" value="US" type="FormField">
    <cfhttpparam name="msisdn" value="11234567890" type="FormField">
</cfhttp>

This docs are looking for a POST and your sending a combo post/get. Based on what your sending over, your not sending the variables. FormField will fix that.
