Google Apps Script receiver

[gloriouslyawkwardlife]

You can use the following Google Apps Script, set up as a web app, as a receiver. This is an example that simply saves the incoming JSON as a timestamped file in Google Drive (the first line of the function), but you can change that first command to parse the JSON and do whatever you like (add to a database, Google Sheet, Big Query, &c.). I do recommend setting the send interval to a long value as doing it every few minutes can max out your Apps Script quota.

function doPost(e) {
  DriveApp.createFile(`${new Date().valueOf()}.overland.json`,e.postData.contents,'application/json');
  var response = ContentService.createTextOutput().setMimeType(ContentService.MimeType.JSON);
  response.append(JSON.stringify({"result": "ok"}));
  return response;
}
