I believe I have it working. Thank you.

I realize that you’re probably not versed in RPG on the IBM I. But this type of thing works all the time. Could you just confirm that the URL contains the source_language, target_language and the text to be converted? The documentation on RAPIDAPI.COM is not very concise.

url = ‘https://text-translator2.p.rapidapi.com/+
translate?source_language=en&target_language=es&+
text=’ + http_urlencode(textIn);

       http_xproc( HTTP_POINT_ADDL_HEADER
         : %paddr(headers) );

      http_req('POST':
                url:
                *omit:
                jsonOut:
                *omit:
                *omit:
                'application/x-www-form-urlencoded');    
									
									The error I'm getting back is that the source_language is required. 

It would be. The program I’m using to make the call is doing a Post.

I’m sorry, but the endpoint ‘/translate’ only supports the POST method
