I have to download the file to system when an API is occur i am using below code may i know how to change my code to for download functionality.

 Global class GETPDF{
global static void sendEmail() {
  GeneratePDFController  c = new GeneratePDFController();
  PageReference ref = Page.AccountDetails;
    Blob b = ref.getContentAsPDF();
  • One simple solution is you can send this pdf to email. SF natively don't provide support for download file. And this is your Web service so i don't think you can use browser for this. Nov 22, 2015 at 10:37

    You can try return pdf as Blob or convert it to Base64 string.

  • @Gres Imporatant factor is content type here. setting content type to application/octet-stream makes that file downloadable and setting content-disposition with filename gives a name to the file. Nov 22, 2015 at 18:42

@Sathya you can do by below way:

global with sharing class FileDownloadService {
      global static void getResponse(){
         RestContext.response.addHeader('Content-Type', 'application/octet-stream');
         RestContext.response.addHeader('Content-Disposition', 'attachment; filename="kiran_machhewarpdf.pdf"');
         PageReference ref = Page.PdfPage;
         Blob pdfBlob = ref.getContentAsPDF();
         RestContext.response.responseBody = pdfBlob;


Page Code: enter image description here I have tested this by exposing this on site. https://kmforce-developer-edition.ap1.force.com/services/apexrest/FileDownloadService You can check by using above endpoint. As a common practice mark this as solution if this helps you.

  • can you plz post your PDF page code

  • @Sathya. There is nothing much in page. In my solution I used renderAs pdf but it will be fine to use normal page getContentAsPDF to get blob. I have updated answer with page code as you asked. I am having very hard time in putting code in Answers. For proper formatting I need to recode here. Thats why I just provided image of page code. Hope this helps you. Nov 22, 2015 at 18:58
  • i tested this service from workbench in that case pdf is not downloading ..

    @Sathya, As discussed in chat, this will work for downloading files. In order to test the same from other end. I have written a java code which is able to download such file. Here is the code--> gist.github.com/kiran-machhewar/… Nov 23, 2015 at 6:09
