Below is my complete process, modified few things:

set up remote site Setup->Security Controle->Remote Site setting. click on New Remote Site



Enter the detailes as in the image and "remote site url" is your ord url

Schedule class:-

global class ScheduleFinacialNotification implements Schedulable {

global string sendSessionId;

global ScheduleFinacialNotification(String sessionId){

this.sendSessionId = sessionId;

}

global void execute(SchedulableContext SC) {

BatchSendFinacialNotification batchApex=new BatchSendFinacialNotification();

batchApex.sessionId = this.sendSessionId;

Database.executeBatch(batchApex,1); }}

Batch class:-

global class BatchSendFinacialNotification implements Database.Batchable<sObject>,Database.Stateful,Database.AllowsCallouts {

public String query;

global string sessionId;

global BatchSendFinacialNotification(){

this.sessionId = sessionId;

query = 'Select Id,Name,Project__r.Go_Live_Date__c from Service_Project_Junction__c ';

}

global Database.QueryLocator start(Database.BatchableContext BC){

System.debug('=========='+Database.getQueryLocator(query));

return Database.getQueryLocator(query);

}

global void execute(Database.BatchableContext BC, List<Service_Project_Junction__c> scope) {

//List<Service_Project_Junction__c> pojJunRecList = [Select Id,Name,Project__c,Opportunity_Deal__c,Project__r.Id,Project__r.Go_Live_Date__c,Product_Opportunity_Junction__r.Service__r.Service_Type__c,Product_Opportunity_Junction__r.Service__r.Product_Price__c,Product_Opportunity_Junction__r.No_Of_Months__c,Product_Opportunity_Junction__r.Total_Price__c,Product_Opportunity_Junction__r.No_Of_Listings__c
from Service_Project_Junction__c where Opportunity_Deal__c != null AND Project__r.Go_Live_Date__c != null];

for(Service_Project_Junction__c proRec: scope){

Integer duration = integer.valueOf(proRec.Product_Opportunity_Junction__r.No_Of_Months__c);

Integer totMonthTillToday = proRec.Project__r.Go_Live_Date__c.monthsBetween(System.today());

System.debug('Test in for loop==>'+proRec);

if(totMonthTillToday <= duration && proRec.Project__r.Go_Live_Date__c.Day() == Date.today().day()){

System.debug(sessionId+'Test in if loop==>'+this.sessionId);

ServiceInvoiceRedirectController.attachPdfToRecord( proRec.Project__r.Id, this.sessionId);

System.debug('Test in if loop after condiyion==>');

}

}

}

global void finish(Database.BatchableContext BC){

}

}

Call of REST Api class:-

@RestResource(urlMapping='/AttachPDF/*')

global class ServiceInvoiceRedirectController

{

@HttpGet

global static void AttachPDFtoRecordREST()

{

RestRequest req = RestContext.request;

id recordId = req.requestURI.substring(req.requestURI.lastIndexOf('/')+1);

PageReference pdfPage = new PageReference('/apex/ServiceInvoicePDF?Id='+recordId);

pdfPage.getParameters().put('id',recordId);

Blob pdf = pdfPage.getContentAsPdf(); //!Test.isRunningTest() ? pdfPage.getContentAsPdf() : Blob.ValueOf('dummy text');

Project__c prjRec = [Select Id,Name,Builder_Name__c from Project__c where Id =: recordId];

//Insert Invoice record for related project

Invoice__c invoRec = new Invoice__c();

invoRec.RecordTypeId = Constants_PicklistVariables.serInvoice;

invoRec.Project__c = recordId;

invoRec.Account__c = prjRec.Builder_Name__c;

try{

insert invoRec;

}catch(Exception e){

System.debug('Invoice=Exception-->'+e);

}

System.debug('Invoice=invoRec.id-->'+invoRec);

//Insert Attacment to the invoice

Attachment a = New Attachment();

a.body = pdf;

a.parentID = invoRec.id;

a.ContentType = 'application/pdf';

a.Name = 'SER-INV-'+invoRec.id+'.pdf';

try{

insert a;

}catch(Exception e){

System.debug('Attachment=Exception-->'+e);

}

//Create the email attachment

Messaging.EmailFileAttachment efa = new Messaging.EmailFileAttachment();

efa.setFileName('pdfName.pdf');//Pleace ad pdf name from contact name project and oppty concatinate

efa.setContentType('application/pdf');

efa.setBody(pdf);

// Create the Singal Email Message

Messaging.SingleEmailMessage email = new Messaging.SingleEmailMessage();

email.setSubject('Financial Notification');

email.setToAddresses(new String[] { 'dagny.fernandes@extentor.com' });//add account email id

email.setPlainTextBody( 'Please Find Attachment your financial report Attached with this email.');

email.setFileAttachments(new Messaging.EmailFileAttachment[] {efa});

// Sends the email

Messaging.SendEmailResult [] r = Messaging.sendEmail(new Messaging.SingleEmailMessage[] {email});

}

// call this method from your Batch Apex

global static void attachPdfToRecord( Id recordId, String sessionId )

{

System.debug('recordId==>'+recordId);

System.debug('sessionId==>'+sessionId);

System.debug('Iam in REST API Call method');

// String addr = 'https://cs5.salesforce.com/services/apexrest/AttachPDF/' + recordId;

HttpRequest req = new HttpRequest();

req.setEndpoint('https://cs5.salesforce.com/services/apexrest/AttachPDF/a04O000000EHJN6IAP');

req.setMethod('GET');

req.setHeader('Authorization', 'OAuth ' + sessionId);

Http http = new Http();

HttpResponse response = http.send(req);

}

}

Schedule class from Developer Console in Anonymous Window:-

Datetime sysTime = System.now();

sysTime = sysTime.addSeconds(5);

String chron_exp =' '+sysTime.second() + ' ' + sysTime.minute() + ' ' + sysTime.hour() + ' ' + sysTime.day() + ' ' + sysTime.month() + ' ? ' + sysTime.year();

System.schedule('Job1',chron_exp , new ScheduleFinacialNotification(UserInfo.getSessionId()));
