That was the problem. Client had not updated Square account with new URL info.
Working now.
Thanks!
Setting up foxnetsoft.SquarePaymentForm on a client site and getting following error when trying to process test order:
Square.Connect.Client.ApiException: Error calling Charge: {"errors":[{"category":"INVALID_REQUEST_ERROR","code":"NOT_FOUND","detail":"API endpoint for URL path `/v2/locations/transactions` and HTTP method `GET` is not found."}]}
at Square.Connect.Api.TransactionsApi.ChargeWithHttpInfo(String locationId, ChargeRequest body)
at Square.Connect.Api.TransactionsApi.Charge(String locationId, ChargeRequest body)
at FoxNetSoft.Plugin.Payments.SquarePaymentForm.Services.SquarePaymentManager.Charge(ProcessPaymentRequest paymentRequest, Boolean isRecurringPayment, String squareToken)
Any idea what is wrong?
