Selling Plan APIs improvement

We’ve improved our Selling Plan APIs to make it easier to identify the default selling plan within a selling plan group.

What’s New?

A new isDefault key is now included under each selling plan. This indicates whether a selling plan is the default selling plan under a selling plan group or not

This is available across the following APIs:

• Storefront: List Selling Plan Groups
• Admin: List Selling Plan Groups and List Available Selling Plan Groups for a Product Variant
