Square Payment Form

Please can you confirm that the Square Payment Form has been upgraded to support the new Square Payments SDK.

We are using the Nopcommerce 4.50 version of your plugin.

"We wanted to inform you that the SqPaymentForm JavaScript library retirement has been extended to 2022-10-31 and its functionality will be shut off after this date. Additionally, new applications will not be allowed to use SqPaymentForm from 2022-07-21.
SqPaymentForm has been deprecated since 2021-05-13 and replaced by Web Payments SDK. "

Kind Regards
Matt Hobson

We plan to upgrade it.

We released the new plugin [url=/squarewebpayments]Square Web Payments[/url].

Will this change also be reflecting in earlier versions of the Plugin as I have some websites running 4.20 and to migrate them to the latest version will be very difficult in the timescales.

Nop 4.20 use the old .NET version. The Square kernel library uses the new one.
I need to recompile this Square kernel library. It's not easy.

Is this the same for the 4.20 hosted version as well ?

Yes.
The plugin for old nop versions (4.30 and older) uses Square TransactionsApi from the Square kernel library.
The new Square kernel library uses PaymentsAPI.
