How is a POST API created and called?

Question

8345.HelloWorldAPIv2.zip 
 I have attached a functioning GET and POST API, but I don't know how to view the json arguments sent to the API. 
 Example:the 'value': 'something to test' string. How do I get to that value in the API?. 
 
 app . api . call ( 'POST' , app . api . buildURL ( 'Hello/World/1' ), { 'value' : 'something to test' }, 
 { 
 success : function ( data ){ 
 if ( this . disposed ){ 
 return ; 
 } 
 console . log ( data ); 
 self . message = data ; 
 _ . extend ( self , self . message ); 
 self . render (); 
 }, 
 error : function ( e ) { 
 console . log ( 'error' ); 
 console . log ( e ); 
 } 
 });

I think the problem lies in Javascript. 
 SugarCRM uses CRUD approach for api calls, so you should not use POST/PUT/GET etc manually. You have to use create/read/update/delete. 
 Eg: 
 app.api.call('read', ... // GET 
 
 app.api.call('create', ... // POST 
 
 app.api.call('update', ... // PUT 
 
 Anything that is not CRUD is considered GET, so your JSON is never sent to backend, which is why you didn't see the value in your API. If you change it to create, it should do a POST and you should be able to see the value in $args. 
 I've tried to document some common snippets and usages here, in case it helps: https://seventunes.com/sugarcrm-javascript-snippets-1/#crud

Hi Amy, 
 All JSON parameters are available as part of your $args variable in your API method argument. 
 This method will require the parameters $api and $args . Any path variables, query string parameters or posted data will be available in the $args parameter for you to work with. 
 From documentation: https://support.sugarcrm.com/Documentation/Sugar_Developer/Sugar_Developer_Guide_10.2/Integration/Web_Services/REST_API/Extending_Endpoints/ 
 
 So if you pass {'value':'something to test'} , you will be able to access it like $args['value']
