Let's make the API first
    1. Open google drive in your favorite browser. Click on the “New”, then select “google apps script”.
    1. You can rename the file if you want. (optional).
  1. Delete all pre-code.
    1. Past the google apps script code here which provide in below.
  1. Click the save icon.
  2. After saving the code you don’t see any alert icon on this part.(see in Image)
  3. Click on the deploy button.
Google Apps Script Code
// kodular coder
function doGet(){
  return ContentService.createTextOutput("online");

function doPost(e) {
  var body = e.parameter.body;
    to: e.parameter.to,
    subject: e.parameter.subject,
    body: body,
    htmlBody: body
  return ContentService.createTextOutput("success");
  1. Click on “Done”.
  2. All done.
Let's move to kodular
    1. Open your :kodular:kodular project.
  1. For testing, you need 3 components. ( Web, Button and Notifier );
  1. Copy our block in your project, and it’s ready to test.
    NOTE: Don’t change the white mark section ( ! importent );

Details: We send a post request in API by web component. If our request succeeded then we got “success” as a response content. Otherwise, the request is failed due to some basic reasons. Such as internet connection error, wrong email address, wrong API, etc.

If I have done something wrong, please let me know so that I can correct my mistake. Because I am not a professional.

Thank you all :blue_heart: :blue_heart:

It is worth noting that:

  • all emails will be sent from the gmail account that created/authenticated the script
  • A "free" google account has a quota of 100 emails per 24 hours
