I am trying to write a REST service which will send SF objects between Orgs. Right now, as a test, I am sending data to the same Org that it is coming from. I wrote a GET request which worked so I know the communcation part is working. But I am now trying to send an Account using POST. My JSON looks like this

    

{
    "acct": {
        "attributes": {
            "type": "Account",
            "url": "/services/data/v34.0/sobjects/Account/0018A000002ryhSQAQ"
        },
        "Id": "0018A000002ryhSQAQ",
        "IsDeleted": false,
        "Name": "Test",
        "RecordTypeId": "012C0000000QakwIAC",
        "BillingAddress": null,
        "ShippingAddress": null,
        "OwnerId": "0058A000000I5WbQAK",
        "CreatedDate": "2015-08-25T16:07:17.000+0000",
        "CreatedById": "0058A000000I5WbQAK",
        "LastModifiedDate": "2015-08-25T16:07:17.000+0000",
        "LastModifiedById": "0058A000000I5WbQAK",
        "SystemModstamp": "2015-08-25T16:07:17.000+0000",
        "LastViewedDate": "2015-08-28T13:54:38.000+0000",
        "LastReferencedDate": "2015-08-28T21:54:40.000+0000",
        "IsPartner": false,
        "IsCustomerPortal": false,
        "Advocacy__c": false,
        "Background_check_required__c": "Criminal",
        "External_Content_Approval_Required__c": false,
        "Indicative_Data_Options__c": "Name",
        "Internal_Content_Approval_Required__c": false
    }
}

**This is the service**

@RestResource(urlMapping='/ClientMigration')
global with sharing class ClientMigrationService {
    static Account clientMigrated;
    @HttpPost
    global static string Migrate(Account Client) {
        //Account a = JSON.deserialize(client);
        /*Map<String, SObject> mapJsonObjects = (Map<String, SObject>)
            JSON.deserialize(Client, Map<String, SObject>.class);
        Account a= (Account) mapJsonObjects.get('Account');   
        
        insert a;
        clientMigrated = a;
        */
        system.debug (client);
        return 'Success';
    }
    
     public class RequestWrapper{
        Account acct;
        public RequestWrapper(){}
    }        
        
 }

    

This is the code calling the service


    

public PageReference Migrate() {

        Account myAct = accountInfo ;

        system.debug('myAct = ' + myAct);

        RequestWrapper rw = new RequestWrapper();

        rw.acct = myAct;

        string myActJSON = JSON.serialize(rw);
        system.debug('myActJSON = ' + myActJSON );
        
        sendAccountDetails(myActJSON );
        return null;
    }
    
    private string sendAccountDetails(string actDetails) {
        HttpRequest req = new HttpRequest();

        req.setMethod('POST');
       
        string endpoint = oauth.instance_url +'/services/apexrest/ClientMigration';
        system.debug('endpoint = ' + endpoint);
        req.setEndpoint(endpoint);
       

        req.setBody(actDetails);
        req.setCompressed(true); 
        req.setHeader('Authorization', 'OAuth '+ oauth.access_token);
        req.setHeader('content-type', 'application/json');

        Http http = new Http();

        HTTPResponse res = http.send(req);

        System.debug('BODY: '+res.getBody());

        System.debug('STATUS:'+res.getStatus());

        System.debug('STATUS_CODE:'+res.getStatusCode());

        return res.getBody();

    }

 public class RequestWrapper{
        Account acct;
        public RequestWrapper(){}
    }

This is the error I keep seeing
Unexpected parameter encountered during deserialization: acct at [line:1, column:10]","errorCode":"JSON_PARSER_ERROR"}]

It seems that no matter what I do it complains at the location in the JSON where it get just past the very first object and gets into the inner objects. I tried doing this without the RequestWrapper and just serializing the account directly but had the same problem. I think I must be doing something wrong with the serialization process.

Does anyone have some suggestions?
Thanks,
Chris
