JSON check on CFC

I have a CFC (call it proxy.cfc) which I use as a proxy for the simple API that I wrote. Everything is going well, and several partners are starting to use the API effectively.

However, one site that is trying to send data does not send valid JSON, and I cannot seem to gracefully handle this error.

A valid JSON string hosted as a URL might look like this:

{"apicomponent":"proxyRemoteAdd","apimethod":"add","apiarguments":{"ph_num":1212,"rbpid":999,"ph_exch":555,"state":"HI","address_1":"123 Main Street","address_2":"","rmtid":"PON83","last_name":"Smith","test":1,"zip":999999,"first_name":"Joe","email":"test@test.com","city":"Honolulu","type":"SP","ph_area":995},"apiauthkey":"abc123"}

And it works great.

However, if this line is truncated for any reason:

{"apicomponent":"proxyRemoteAdd","apimethod":"add","apiarguments":{"ph_num":1212,"rbpid":999,"ph_exch":555,"state":"HI"

I will catch the exception as follows: Exception: JSON parsing error: Unexpected end of JSON string

This comes from my onError in Application.cfc. I added code to isolate it in Application.cfc as follows:

<cfif ARGUMENTS.EXCEPTION.MESSAGE IS "JSON parsing failure: Unexpected end of JSON string">
 <!--- do some stuff here ---> 
</cfif>

? - proxy.cfc, ? , Application.cfc proxy.cfc.

UPDATE - . , :

<cfhttp url="https://www.domain.com/api/proxy.cfc" method="post" result="httpResult" charset="UTF-8">
  <cfhttpparam type="url" name="method" value="apiauth"/>
  <cfhttpparam type="url" name="argumentCollection" value="#jsData#"/>
