I've read and re-read the documentation provided for configuring the EasyStore Paypal payment plugin, but unsurprisingly it doesn't work on my site, in either Live or Sandbox mode.
The reason for this is that the plugin is not passing required parameters to PayPal - i believe including API username and secret; yet there is no way of configuring this information in EasyStore: not is there any documentation about what API / webhook return URL settings require to be configured in PayPal.
At the moment, this leaves the PayPal plugin completely useless and unable to be used.
Can someone from Joomshaper please look in to this and provide complete setup instructions for PayPal?
