Paypal REST API Subscription Doesn’t Process

Thanks for an awesome plugin. We recently moved from Yith Subscriptions with standard Paypal Checkout which worked, but provided a less than ideal UX for the consumer. Users had to login to Paypal to cancel subscriptions.

As a better experience, we’d like to use your “Subscriptions for WooCommerce”, aka WebToffee Subscriptions, and wanted to integrate using “Paypal for WooCommerce” plugin with the Paypal Credit Card (REST) payment option. This way, the user didn’t have to visit Paypal to setup an account, and they could also stay onsite to manage their subscription.

However, we’ve not had any luck with getting the Subscriptions to process.

We’ve tried with and without the ‘Billing Agreement’ checkbox. I know the credentials are good, as I also run transactions with the Sprout Invoicing platform just fine.

Here is an example of a Live Transaction error message:

The customer gets a message ‘Error Processing Checkout’, and it appears as a Pending Payment in my orders.
