Salesforce Integration example

Salesforce POST Method Integration
===================================
/*
    In this example, we get the account name from any other platform or any other salesforce. If the insertion process is success, we send the response as 'success'.
 
    - 'postconnectform' - This is the URL for this class. We can call this class using this URL with session Id of this Org.  
        Ex: https://ap1.force.com/services/apexrest/postconnectform/
 
    - https://ap1.force.com - is salesforce org instance
        Note: we need to change the url form salesforce.com to force.com
 
    - /services/apexrest - standard syntax
*/

***************************************************
Example for inserting a Account with requested name
***************************************************

@RestResource(urlMapping='/postconnectform/*')
global class AccountForm {  
 
    public class AccountClass{
 
        public String Name;
     
    }
 
    @HttpPOST
    global static string postFormRegistration(){
     
          try{
     
            RestRequest req = RestContext.request;
            Blob body = req.requestBody;          
            String JSONString = body.toString();
            AccountClass RegCls = new AccountClass();
            RegCls = (AccountClass)JSON.deserialize(JSONString, AccountClass.class);
         
            if(RegCls != NULL){
                Account acc =  new Account();
                acc.Name = RegCls.Name;
                insert acc;
            }
        }catch(Exception e){
     
        }
        return 'success';
    }
}
