I am trying to understand whether PaymentSense, the payment processor (which is a partner of authorize.net) is an approved 3rd party/compatible with subscription payments? The only difference between PaymentSense and Authorize.net to my knowledge is the contracting entity as PaymentSense is a partner and uses the same technology. Authorize.net is only available to US/Canada and our business is in the UK.
Our business cannot use Shopify payments or Paypal Express so the only other option is 'Authorize.net '
Thank you for your patience while I looked for an answer to your inquiry. Unfortunately, PaymentSense is no longer a supported payment processor. Here is a list of payment gateways currently available to UK merchants: https://www.shopify.ca/payment-gateways/united-kingdom
May I ask why Shopify Payments or Paypal Express is not suitable for your business?
