Changes to order and payment testing on all development stores
Beginning today, partners who want to test orders in development stores can only process payments using the following methods:
* Shopify's test payment provider (Bogus Gateway).
* A payment provider set to test mode.
If you want to test your development store using real transactions, then you can select and purchase a Shopify plan in the account settings of your development store.
This change was applied to all newly created development stores on March 30, 2020, as mentioned in our changelog update here. Beginning September 14, 2020, this change will be applicable across all development stores.
