Vendor plugin
Yes. Square publishes and maintains its own free extension for Magento 2 and Adobe Commerce (square/module-squareup-omni) on the Adobe Commerce Marketplace. It is at version 1.19.0 (updated 29 December 2025) and covers payments plus catalog, inventory and customer sync. Webkul sells a paid, payments-only alternative.1
Connects through Marketplace extension installed with Composer (square/module-squareup-omni); Square-hosted card form plus express wallet buttons. Biggest gotcha: Square's two pages disagree on dates and countries.
| Capability | On this integration | Notes |
|---|---|---|
| Cards | Yes1 | Card payments through a Square-hosted iframe, with Authorize Only or Authorize and Capture as the payment action. |
| Apple Pay | Yes1 | You have to register and verify the store domain in the Square Developer Console before Apple Pay works. |
| Google Pay | Yes1 | Listed as a checkout and express-checkout method. |
| ACH bank payments | Yes1 | ACH bank transfer is listed as a payment method; release 1.19.0 reworked the ACH integration. |
| Buy now, pay later | Yes1 | Afterpay, added in release 1.14.0 and available in express checkout. |
| 3-D Secure | Yes1 | 3D Secure / SCA is switched on under Stores > Configuration > Sales > 3D Secure; release 1.12.0 made it possible to turn off. |
| Saved cards (vault) | Limited2 | Customers can save cards when card-on-file is enabled, but not on admin-created orders or while 3DS is enabled. |
| Subscriptions | Yes1 | Subscription plans are billed through Square invoices, and each paid invoice creates a Magento order. |
| Partial refunds | Yes1 | Refunds run from Magento credit memos; release 1.14.3 fixed orders refunded in two or more partial refunds. |
| Multi-currency | No3 | Square charges in the seller location's single currency; release 1.16.0 fixed amounts when base and display currencies differ. |
| Network tokens | Not verified here4 |
Capability status reflects the integration and documentation available at the time of verification, not necessarily every capability of the underlying gateway or platform.
Create a Square application in the Developer Console to get Sandbox credentials. Enter them in the extension's Square configuration (Stores > Configuration > Square), pick a location and complete the OAuth token step. Sandbox v2 has been supported since release 1.5.0, and gift cards since 1.8.0. Apple Pay needs its own domain registration in Sandbox and in production over HTTPS (localhost does not work), and Apple Pay rejects Sandbox test cards, so test it with a real wallet card. Webhooks need a public HTTPS URL. Sync jobs run on cron, mostly twice an hour, so run cron or wait before asserting on catalog, inventory, customer or transaction sync. For payments, check the order status (Processing, and whether the amount was authorized or captured), a void on cancel under Authorize Only, and credit-memo refunds showing in the Square Dashboard.1
UAT-Ops runs integration flows like this against the real sandbox and keeps the evidence. Get one email when it opens.
The Adobe Marketplace listing shows version 1.19.0 updated on 29 December 2025 and limits availability to the US, Canada, the UK, Australia and Japan. Square's own App Marketplace page was last updated on 7 February 2024 and lists eight countries, adding Spain, France and Ireland. Before promising support in Ireland, France or Spain, confirm it with Square and check the Adobe release notes, not the Square page.

From 2.4.7, Adobe runs CSP in restrict mode on payment pages. Inline scripts that are not whitelisted get blocked, and the payment methods can quietly disappear. Patch releases of 2.4.4 to 2.4.6 are affected too. Square added CSP enforcement compatibility in extension 1.18.0 for 2.4.6-p6+ and 2.4.7-p1+, so an older copy of the module on a patched store is a likely cause of a blank checkout.

Square's user guide says customers cannot store a card while 3DS is enabled, and cannot use a stored card on orders created in the Magento Admin. Merchants in regions where SCA is required have to choose between buyer verification and card-on-file convenience. Test both settings before launch, not just the default.

Catalog, inventory, customer, transaction and refund sync run as Magento cron jobs, mostly twice an hour, and the OAuth token is refreshed once a day at 4 am. If Magento cron is not running, stock goes stale and the token eventually expires. Release notes list token-renewal fixes in 1.13.2 and 1.16.2.

Release notes return again and again to amounts that do not match between the two systems. Version 1.19.0 fixed tax being calculated on the discounted price regardless of Magento's tax settings, plus rounding on fractional quantities. Version 1.16.0 fixed stores whose base and display currencies differ. Reconcile a sample of orders after every upgrade.

Where newer information, testing, or vendor documentation materially changes a published claim, UAT-Ops may revise the page to reflect the most current verified information. Readers should confirm time-sensitive requirements with the relevant vendor before making production or purchasing decisions.
