Integration of Fondy payment in Shopify (automatic order amount)

Budget: 1500 UAH Deadline: 1 day

Hello.
I can specifically close this integration: automatically transfer the order amount from Shopify to Fondy, create a checkout URL, and redirect the customer to payment without manual entry of the amount.
Considering that you already have a Vercel backend and access, the solution can be made simply and without unnecessary overhead.

Hello.

I am a NodeJS developer. I have experience with Fondy and Shopify. I am ready to take on the project. Write to me, we will discuss.

Good day.

I can implement this integration without third-party paid applications: retrieve the order amount from Shopify after checkout, send it to your Vercel backend, create a payment in Fondy via API, and redirect the customer to the checkout URL with the amount already filled in.

I will create a simple and clear solution for your current setup: Shopify + Vercel + Fondy.

If needed, I will also take into account the proper handling of the response from Fondy, so that the connection works stably and does not just perform a redirect.

I am ready to discuss the details and start quickly.

Good day!
I have 3+ years of experience in Shopify development and payment system integrations through API.
I can implement the integration of Fondy without third-party paid applications: receive the order amount after checkout, send it to Fondy via API, create a checkout URL, and redirect the customer to the payment page with the correct amount.
I will also consider your current setup with Vercel backend and GitHub to ensure the solution is simple, clear, and does not require manual entry of the amount by the customer.
I suggest discussing the details, as well as the cost and timelines, in private messages.

Hello, Daria!

Your stack is already set up correctly — Shopify + Vercel backend + Fondy credentials. The rest is about ~150 lines of code on the Vercel serverless function.

Implementation plan:

1. On the Order status page (Thank you), we set the link in the "Pay now" button to your Vercel endpoint with parameters order_id + total in the URL (Shopify Liquid: {{ order.order_number }} and {{ order.total_price }}).

2. Vercel function /api/fondy-checkout (Node.js):
— Accepts order_id and amount
— Validates HMAC signature from Shopify, so no one can substitute someone else's amount
— Builds payload for Fondy API (PSpaymentapi.fondy.eu/api/checkout/url): merchant_id, order_id, amount (in kopecks), currency UAH, signature SHA1(merchant_password + sorted_params)
— Calls Fondy, receives checkout_url
— Performs a 302 redirect for the client to checkout_url

3. Webhook /api/fondy-callback receives confirmation from Fondy after payment:
— Checks the signature
— Updates the Shopify order status via Admin API (Order → Mark as paid)
— Logs the transaction

4. Test run in Fondy sandbox + bug-fix.

5. Documentation: README in your GitHub repo with env variables and deployment steps.

What I need from you (via messaging here):
— Access to the GitHub repo (collaborator) OR a ZIP with the project
— Shopify Admin API token with read_orders + write_orders permissions
— Test Fondy sandbox keys (do not show live ones)

Rate: 1,500 UAH for code + tests in sandbox + documentation. Deadline: 2 working days.

No calls, only messaging. If something doesn't work after deployment — I will fix it for free within 7 days. Expand

Hello! Shopify does not provide secure access to the order amount and payment API from the Thank You page, I propose a solution with backend implementation on a cloud platform like Vercel. About myself: I have experience in creating websites from scratch using PHP, HTML, CSS, AJAX, JS, as well as on WordPress WooCommerce. I specialize in theme development, content integration using ACF, working with page builders Gutenberg and Elementor, as well as responsive layout. I also develop plugins for WordPress in PHP. I would be happy to collaborate!
