Is there any REST service available in Salesforce to Convert Leads into Accounts

Question

We have to convert Leads to accounts via REST -OAuth calls. We are able to create, update(Edit) and Detail Lead fields but not able to convert them.

We found the same is possible via SOAP API but we are following REST OAuth only.

Yes and we resolved this by creating an Apex class for REST call. Sample code is this -

@RestResource(urlMapping='/Lead/*')
global with sharing class RestLeadConvert {            

    @HttpGet
    global static String doGet() {
        String ret = 'fail';
        RestRequest req = RestContext.request;
        RestResponse res = RestContext.response;
        String leadId = req.requestURI.substring(req.requestURI.lastIndexOf('/')+1);              
        Database.LeadConvert lc = new Database.LeadConvert();
        lc.setLeadId(leadId);

        LeadStatus convertStatus = [SELECT Id, MasterLabel FROM LeadStatus WHERE IsConverted=true LIMIT 1];
        lc.setConvertedStatus(convertStatus.MasterLabel);           
        Database.LeadConvertResult lcr ;
        try{
            lcr = Database.convertLead(lc);
            system.debug('*****lcr.isSuccess()'+lcr.isSuccess());            
            ret = 'ok';
        }
        catch(exception ex){
            system.debug('***NOT CONVERTED**');           
        }
        return ret;
    }   
}

And you can use this call by

<Your Instance URL>/services/apexrest/Lead/<LeadId>

This test will give you around 93% of coverage.

@isTest
public class RestLeadConvertTest{

    static testMethod void testHttpGet() {
        Lead l = new Lead();
        l.FirstName = 'First';
        l.LastName = 'Last';
        l.Company = 'Unit Test';
        insert l;

        Test.startTest();
        RestRequest req = new RestRequest();
        RestResponse res = new RestResponse();
        req.requestURI = '/Lead/' + l.Id;
        req.httpMethod = 'GET';
        RestContext.request = req;
        RestContext.response= res;
        RestLeadConvert.doGet();
        Test.stopTest();
    }

}
