Where does Commerce Stripe store the plans that are created on my stripe account? I have a stripe account all setup and I have created plans. In Drupal Commerce I have created products, but I realised it should have pulled the "plans" down from stripe. I have also tried the stripe payment module which did pull the plans down, but it would have required a lot of customisation to work well with the roles that we needed to assign per plan.

Where does Commerce Stripe store the plans created on my stripe account?
While I'm not familiar with Stripe, it looks like the commerce_stripe stores the details in the remote Stripe system via the stripe-php library

e.g, in commerce_stripe_submit_form_submit

Stripe_Customer::create
...
Stripe_Customer::retrieve


The other place for payment gateway settings will be on the individual payment method configuration form under Rules.
