Andy Chase has published a Google Script that will let you automatically post Google Form submissions to a Slack channel. You need to place the script inside the script editor of your Google Forms editor and associate the onSubmit() method with the Form Submit trigger.
// replace this with your own Slack webhook URL // https://crowdscores.slack.com/services var webhookUrl = 'https://hooks.slack.com/services/****/****/****'; function onSubmit(e) { var response = e.response.getItemResponses(); // Setup 2: // Modify the below to make the message you want. // See: https://developers.google.com/apps-script/reference/forms/form-response var d = e.response.getRespondentEmail() + " | " + response[0].getResponse(); var payload = { "payload": '{"text": "' + d + '"}' } var options = { "method": "post", "payload": payload }; UrlFetchApp.fetch(webhookUrl, options); };
