Its Premium Swish Gateway for LatePoint.
Swish Gateway for LatePoint works like any standard WordPress plugin, and once installed and enabled, it will automatically add a Swish to your website which has LatePoint plugin installed and enabled.

As an addition to the plugin, you need the service Swish LatePoint that you order from one of the Swedish banks offering the service. Ask your bank if it does. Swish LatePoint is a special service developed for LatePoint and differs from the normal private “Swish” service and the corporate Swish corporate. Some banks have made it possible to order the service online in their internet bank but most of the banks still require a filled in and signed form to be sent in.

Its works for the following methods.

LOCAL CERTIFICATE

If your bank is not supporting the choice of technical supplier you can create a certificate of your own and place it on your webserver. You will find instructions for doing this in our installation description.

SIMULATOR

If you just want to see what the plugin will look like on your website or if you need to test payments in your staging or test environment you can configure the plugin to simulate payments.
Payment done via the simulator is done by a pre-configured fictive mobile number and will be automatically approved by the system. Because of this, you can not see how the payment will look like in the Swish-app
