This integration requires a paid Webflow plan to allow embedding custom scripts into your site.
To allow sign ups to your audience from your Webflow site, you can utilise a native Webflow form plus some drop-in JavaScript.

​
Add a custom form script to your Webflow site

If you do not add the custom script in the correct place, the form may not work properly.
To submit data to Loops seamlessly from your Webflow site we provide some JavaScript, which can be added to your site.

Get the script

Use this script in your Webflow page.

​
Where to add the script

  • If you have a Loops form on every page of your site, add this code to the “Footer code” section in your Site settings (read how in the Webflow docs).
  • If you have a Loops form on only one page, add this code to the “Before </body> tag” section in your Page setting (read how in the Webflow docs).

​
Add a form to your page

Next you need to create a form in your Webflow page. Use the “Input” and “Button” elements. When you add new fields, make sure the “Name” value in the field’s settings panel matches the name of the field in Loops: email, firstName, etc. You can check the full list of your available properties from your API Settings page.
Please make sure these contact properties already exist in your Loops account. You can add new contact properties in API Settings, with a CSV import or using the API.

​
How to add hidden fields

You may want to assign a property to all contacts that submit the form (for example, source or userGroup). For this add an “Embed” component inside your form on the same level as your input and button elements. In this Embed element add a hidden text field that passes on the custom value to Loops (make sure the name values match the “API Name” values in your API Settings). 
<input type="hidden" name="mailingLists" value="cly2xnjbn002z0mme68uog1wk, cly4xnjbn002x0mme28uog1wk" />

<input type="hidden" name="source" value="Webflow" />

<input type="hidden" name="userGroup" value="Some User Group" />

<!-- This also works with other default contact properties... -->
<input type="hidden" name="firstName" value="Barbara" />

<!-- ... and custom contact properties -->
<input type="hidden" name="signupPageUrl" value="https://yourdomain/this-page-url" />
Mailing lists need to be marked Public in your Lists settings in order for them to work in forms.
Here’s how it looks in the Webflow editor:

​
Add your Loops form endpoint URL

The last step is to make sure your form submits data to Loops. You do this by adding a Loops form endpoint as the form’s “Action” value.
  1. Go to the Forms page in your Loops account.
  2. Click on the Settings tab.
  3. Copy the URL shown in the Form Endpoint field.
  4. In Webflow, click on your Form Block, go to the Settings panel and paste the URL into the Action field.
Our form submission endpoint has rate limiting, so you will see an error in testing if you submit more than once per minute or submit the same email twice.
