Has anyone successfully integrated a Stripe custom variable API to a Webflow form for end-customers to input a specified amount, such as for donations?

Yes, it is possible to integrate Stripe's custom variable API with a Webflow form to allow end-customers to input a specified amount, such as for donations. Here's a step-by-step guide on how to achieve this:

1. Set up your Stripe account: If you haven't already, sign up for a Stripe account at stripe.com. Once you've created an account, navigate to the Dashboard and retrieve your API keys.

2. Create a form in Webflow: Log in to your Webflow account and navigate to the Designer. Create a new form or use an existing one where customers can input their desired donation amount.

3. Add an HTML Embed element: In the Designer, drag and drop an HTML Embed element onto your form or page. This element allows you to inject custom HTML code into your Webflow project.

4. Set up the HTML Embed element: Double-click on the HTML Embed element and paste the following code:

<form id="stripe-form">  <label for="donation-amount">Donation Amount:</label>  <input type="number" step="0.01" min="0" id="donation-amount" required>  <script src="https://checkout.stripe.com/checkout.js"></script>  <button type="submit">Donate</button></form><script>  document.getElementById('stripe-form').addEventListener('submit', function(event) {    event.preventDefault();        var amount = parseFloat(document.getElementById('donation-amount').value) * 100; // convert to cents        var handler = StripeCheckout.configure({      key: 'YOUR_STRIPE_API_KEY',      locale: 'auto',      token: function(token) {        // Send the token to your server to create a charge or save it for future use        // You can make a POST request to your server using Fetch API or XMLHttpRequest        fetch('/charge', {          method: 'POST',          body: JSON.stringify({            amount: amount,            token: token.id          })        })        .then(function(response) {          if (response.ok) {            // Handle successful payment          } else {            // Handle failed payment          }        })        .catch(function(error) {          console.error(error);          // Handle errors        });      }    });        handler.open({      name: 'Your Organization',      description: 'Donation',      amount: amount    });        // Close Checkout on page navigation    window.addEventListener('popstate', function() {      handler.close();    });  });</script>

1. Replace 'YOUR_STRIPE_API_KEY' with your actual API key: In the code, replace 'YOUR_STRIPE_API_KEY' with the publishable API key you obtained from your Stripe account.

2. Customize the form and styling: Modify the HTML code to match your desired form fields and styling. You can add additional form fields and validation, as needed.

3. Publish and test your form: Save and publish your Webflow project. Test your form by entering a donation amount and submitting it. If everything is set up correctly, you should see the Stripe Checkout window open, allowing you to complete the payment process.

By following these steps, you can successfully integrate Stripe's custom variable API with a Webflow form to collect specific donation amounts from end-customers.
