Survey Embedding

Embed zeffi surveys into your webpage as a part of the page via iframe, or as a popup survey. Communicate with your surveys using our easy client API.

 

Make sure your survey is in Published state. The embeddings are disabled if the survey is in Unpublished or Offline state. 

Embedding via iframe

You can embed the survey via iframe using the following sample code.

<iframe src="https://survey.zef.fi/KEY/" width="100%" height="640px" hspace="0" vspace="0" scrolling="no" frameborder="0" marginwidth="0" marginheight="0" style="min-width: 320px; max-width: 960px" onmousewheel=""></iframe>
Make sure to replace the `KEY` with your web embed key that you get when you create a web embed

Popup via JavaScript

To create a popup survey, put the following script inside your page header tag.

<script src="https://zef.fi/s/zeffi.js?key=KEY1,KEY2,KEY3" async defer></script>
Make sure to replace the `KEY*` with your survey's popup key that is generated when you create a new popup. You only need as many keys as the number of surveys you wish to add as popups.

Survey communication

Make your embed or popup talk with your website by listening to events.

Note: Make sure to specify an origin in Zeffi, otherwise no event will be sent. You can find this under the advanced settings of your embed or popup.

The wildcard (*) is allowed, but strongly discouraged.

Read more here about the proper usage.


window.addEventListener('message', onMessageReceived); function onMessageReceived(message) { if (message.origin === 'https://survey.zef.fi') { // you have received a message from the survey // use message.data.type to get the message type // use message.data.data to get the message payload } }
