One-Page Checkout Setup on Tilda + Mollie Integration (Orders API / Klarna) + JS Slider Order Description: Hello! I need to set up a one-page checkout on an existing Tilda website (on our subdomain). What needs to be done: Set up a simple form/cart on Tilda (Name, Phone, Email, detailed shipping address to Italy). Implement a ready-made JS script (provided in the specifications) for an interactive price slider. When dragging the slider, the amount should dynamically update and be transferred to the native Tilda cart. Connect the Mollie payment system via the built-in Tilda module. Critically important: switch the integration to Orders API mode to transfer detailed order data (name, quantity, m², VAT). This is necessary so that Klarna installment payment options are activated on the payment screen for Italian customers. Design a page footer based on the provided legal data (in Italian) to pass the Klarna audit. A detailed, step-by-step Technical Specification with all the details, field structure, and ready-made JS code for the slider is attached as a PDF file to this order. Requirements: Experience with Tilda (shopping cart setup, custom HTML/JS T123 blocks). Understanding of payment gateways (experience with Mollie/Stripe is a huge plus). Prompt delivery. Work is tested in Mollie Test Mode.

Hi there, A common pitfall with Tilda and Mollie setups is that the default built-in module often falls back to the basic Payments API instead of the Orders API, which immediately hides Klarna installments at checkout and causes your Italian customers to abandon their carts. I will correctly inject your custom JS slider into a T123 block to feed dynamic pricing directly into the native Tilda cart, while explicitly overriding the payment payload to utilize the Orders API with full line-item tax and m² breakdowns to ensure you pass the Klarna audit seamlessly. Before we hop on a call to review the PDF specification, here are my questions: Does your provided JS slider script already account for Italy-specific VAT calculations, or should that logic be handled programmatically inside the Tilda cart integration? Do you already have an approved Mollie merchant account with Klarna actively enabled for the Italian region in your dashboard? Drop me a message so we can get started right away.

Hello, Could you share your current Tilda website link so I can review the existing setup? Setting up a one-page checkout involves creating a custom form for order details and implementing the JS slider for dynamic pricing. I’ll ensure the Mollie payment system integrates smoothly with the Orders API for detailed order data, enabling Klarna options for your Italian customers. To clarify your requirements, I have a few questions: 1. Are there any specific design elements you want for the checkout page? 2. Do you have a preference for how the order confirmation is displayed after checkout? 3. What is your desired timeline for launching the new checkout system? 4. Is there any additional functionality needed for the price slider beyond what’s provided in the specifications? 5. Will you provide the legal text for the footer, or should I draft it based on common practices? Costs and timelines can be refined after I have more details. I look forward to your response!

Hey — saw your post about setting up a one-page checkout on Tilda with Mollie (Orders API / Klarna) and a JS slider for the order description. The tricky part here is usually keeping the slider logic perfectly in sync with the amount and order details passed to Mollie, so nothing breaks at payment step. Quick question before I suggest an approach: Do you already have Mollie fully configured (API keys, webhooks, Klarna enabled), or does that still need to be set up from scratch? I’ve integrated Mollie (including Klarna) with custom JS frontends before, handling dynamic amounts and order descriptions without breaking the UX. If you send your Tilda link, current setup, or a short spec, I’ll review it and tell you exactly what’s needed to get this working smoothly.

I understand you need to integrate Mollie payments and a custom JS slider into your Tilda one-page checkout, similar to how dynamic pricing modules are often linked to carts. My experience setting up complex payment gateways and front-end interactions on various platforms, including Tilda, will ensure a seamless integration. My approach involves leveraging Tilda's existing form builder for the checkout fields and then strategically embedding the provided JS slider script. I'll ensure the slider's output correctly updates the Tilda cart's total via its API or custom form field manipulation. For Mollie, I'll utilize the built-in Tilda module, configuring it precisely for your account and testing thoroughly with the Orders API and any Klarna-specific requirements. To confirm scope, are there any specific error handling requirements for the JS slider or Mollie transactions? I'm confident I can deliver this efficiently. Let's schedule a quick chat to discuss the project details further.

This project is similar like building one smooth checkout counter where slider pricing, cart and Klarna payments all need update together without breaking the flow. I worked before on similar Tilda and payment integration projects with custom JS logic, checkout customization and Mollie gateway configuration. I think pushing all detailed order data correctly through Mollie Orders API is the most important part so Klarna approval works properly for Italy customers. As a web full stack developer with 8 years of experience, I am very good with JavaScript. I expect it will take 4 days to complete this project. May I ask a question first? Is the Tilda store and Mollie account already connected now or should the full setup start from zero? Waiting for your response. Vasyl
