The Webflow Package is a wrapper around the DOM Package, adding data attributes to access different Memberstack methods directly in your Webflow project. This guide provides a complete list of available data attributes, their functions, and usage examples. The Webflow Package is included in the Webflow install script.

    William de Broucker great idea!

    I have a few ideas, but I'm curious why you'd like this attribute? What would it help you to accomplish?

    Hello !

    I would like this attribute in order to use it in a cancelation form (in order to cancel the user via the Stripe API in Make). 
    Currently I'm using a script to extract the StripeCustomerId but that would be easier to have it in as an attribute

    William de Broucker Would you mind sharing the script you're using to extract the StripeCustomerID?

    Sure :) 

    Inside the form I hide then field stripeCustomerId which is empty at first
    <input type="hidden" name="stripeCustomerId" id="stripeCustomerId">

    and then I use this script (made using chatGPT) , then I collect the stripeCustomerId in a webhook in order to given the discount using the Stripe API

    const memberstack = window.$memberstackDom
    memberstack.getCurrentMember().then(({ data: member }) => {
        // Find the hidden input field and set its value to the stripeCustomerId
        document.getElementById('stripeCustomerId').value = member.stripeCustomerId;

    $(document).ready(function() {
        $('#wf-form-Cancelation-Form').submit(function(e) {

            var formData = $(this).serialize();
            console.log('Form data:', formData);  // check the serialized form data
            var actionUrl = $(this).attr('action');

            $.post(actionUrl, formData)
                .done(function() {
                    window.location.href = "/membership/offre-annulation";
                .fail(function() {
                    alert('There was a problem with the submission. Please try again.');
