1&1 service doesn't allow to add scripts directly into the website's footer. So, for this integration to work, follow these steps.
1. Go to your 1&1 dashboard and select developer mode. Click here.
2. Go to the page where you want to install your booking widget.
3. Click on Insert Items and then Widget / HTML click and drag and drop the icon wherever you want to display the booking widget.
4. Add the tag <div> followed by the <script> inside the <footer> tag as such:
<div class="load-turitop" data-service="P1" data-lang="es" data-embed="box"></div> <script id="js-turitop" src="https://app.turitop.com/js/load-turitop.min.js" data-company="D1" data-buttoncolor="green" data-afftag="ttafid" ></script>
Keep in mind: in the code, "P1" must be replaced with the code of the service or category you want to install, "es" corresponds to the language in which you want to install it, and "D1" is the code of your company in TuriTop or commonly named short_id.
