The order is created after a successful payment, so the store stays fully compliant with Shopify rules and protected from suspension.

three ways to connect online acquiring to Shopify — and why it matters
There are three fundamentally different ways to connect online acquiring (including WayForPay) to Shopify in the Ukrainian market: through the official Shopify Payment Apps API (our approach), through a Manual Payment Method with redirect (Walnut MultiPayments), or through a third-party checkout that replaces Shopify Checkout (Chekly). Only the first method is authorized by Shopify — the other two violate the platform's rules in different ways.
| parameter | TradeMinister (Payment Apps API) | Walnut MultiPayments (Manual Payment Method) | Chekly (third-party checkout) |
|---|---|---|---|
Integration mechanism |
✅ Shopify Payment Apps API (official) | ⚠️ Manual Payment Method + redirect to provider | ❌ Third-party checkout replacing Shopify Checkout |
Compliance with Shopify ToS (clause 4.5) |
✅ official mechanism | ⚠️ gray area (Manual PM not for online payments) | ❌ direct violation of clause 4.5 (prohibition of Checkout replacement) |
When an order is created |
after successful payment | pending payment | after payment in an external checkout, it is imported via API |
Payment placement |
in the standard Shopify Checkout | on the Thank You Page after placing an order | on a third-party domain instead of Shopify Checkout |
Shopify review process |
✅ yes | ❌ no | ❌ no (Shopify does not allow Checkout replacement) |
Source of criteria — official Shopify Payment Apps API documentation and Shopify Acceptable Use Policy. Shopify explicitly requires that all online sales go through the standard Shopify Checkout — replacing Checkout with a third-party solution is considered a direct violation of the platform and Partner Program rules. The Manual Payment Method is intended for offline payments (bank transfer, cash on delivery), not for online acquiring — its use with a redirect to a payment page is a gray area.
which option to choose: Thank You page or Shopify Checkout
We offer two options for connecting WayForPay to Shopify. They differ not only in price but also in operation logic: the Thank You Page option starts at 8,800 ₴ (3 connection options); QR payment (NBU standard No. 97) is available upon request as a separate service. The Checkout option via Payment Apps API is more expensive but provides clear financial reporting without pending orders and standard mainstream gateways.

advantages of Checkout integration
how it works
the customer selects WayForPay at Checkout
On the standard Shopify Checkout page (Payment step), the customer sees the option "Pay via WayForPay" alongside other payment methods. Icons of supported methods are displayed: Visa, Mastercard, Apple Pay, Google Pay, installment payments (monobank Installments, PrivatBank Installments). The customer selects the option and clicks "Pay now."
redirect to the secure WayForPay page
Shopify uses the Payment Apps API to send the amount and session ID data to the payment app servers. The buyer is directed to a branded WayForPay page with your store's logo. They complete the payment using a regular card, Apple Pay, Google Pay, or choose installment payments (monobank or PrivatBank) with real-time application approval.
The order is created and confirmed automatically
After a successful payment, WayForPay returns a confirmation via a service-URL callback with an HMAC-MD5 signature. The Payment Apps API notifies Shopify, and the order is created in the admin panel immediately with the status Paid. The buyer is directed to the standard Thank You Page. When paying in installments, the seller receives the full amount immediately — the buyer pays the interest to the bank. If the payment fails, the order is not created, and the buyer is returned to the Checkout for another attempt.

real turnover expense calculator
Calculate the total WayForPay Checkout commission including the Shopify tariff and Payment Apps fee. The standard WayForPay rate of 2% applies to both Ukrainian and foreign cards — the slider below is retained for compatibility.
The calculation includes the Shopify third-party fee, developer commission (0.4%), Shopify platform fee (0.35%), and WayForPay acquiring commission of 2% (standard). With increased turnover, an individual WayForPay rate is available — in this case, the total commission decreases accordingly. For turnovers from ₴500,000/month, switching to the Shopify Advanced plan pays off in 2–4 months. Offering installment payments usually increases the average check by 15–30% — this effect is not accounted for by the calculator.

frequently asked questions
In the Thank You Page option, the order is created before payment — the customer first places the order, then pays. In the Checkout option, the order is created only after successful payment — this is the standard scheme of mainstream payment gateways. No unpaid orders, no manual moderation. The WayForPay on Thank You Page option is available from 8,800 ₴. QR payment (NBU standard No. 97) — on request, as a separate service.
Works through the official Shopify Payment Apps API — this is the standard mechanism that Shopify provides for payment providers. A ready-made payment app that has already passed Shopify review is used. The store fully complies with Shopify's rules (including clause 4.5 of the ToS regarding the use of Shopify Checkout) and is protected from blocking. API documentation: shopify.dev/docs/apps/build/payments.
Consists of four components: 1) third-party transaction fee Shopify (depends on the plan — from 0.6% to 2%), 2) developer commission 0.4%, 3) Shopify platform fee 0.35%, 4) WayForPay acquiring commission 2% at the standard rate (or an individual rate with increased turnover). Total from 3.35% to 4.75% depending on the Shopify plan. Detailed breakdown is in the "technical details" section.
Through the standard Shopify Admin — the Refund button on the order page. The Payment Apps API automatically sends the refund request to WayForPay via the refund method. Funds are returned to the buyer's card within the standard timeframe (up to 10 banking days). For installment payments, the refund closes the installment plan — the bank stops charging the buyer monthly payments.
1–3 business days after application approval. Steps: installing the ready-made Shopify Payment App in the store, setting up WayForPay details and individual entrepreneur/LLC information, activating payment methods (Apple Pay, Google Pay, installment payments via monobank and PrivatBank), testing with a real order, providing instructions. No custom development for the store is required — a ready, proven solution is used.
No. After a one-time connection fee, there are no additional TradeMinister fees for using the app. The client only pays transaction fees — the breakdown by Shopify pricing plans is provided in the "technical details and fees" section. Server infrastructure, monitoring of service-URL callbacks, and updates for changes in the WayForPay / Shopify API are included in the developer's fee (0.4% per transaction).
Yes. WayForPay accepts cards from any banks, including foreign ones. The standard WayForPay rate (2%) applies equally to Ukrainian and international cards. For customers from other countries, Apple Pay and Google Pay are also available. If international sales are a key channel, we recommend using Shopify Markets for correct price display in the local currency.
