Enable trial period billing using trialDays parameter in EnsureBilling class #240
Description
Overview
The Shopify PHP app template already supports, using the EnsureBilling class, the management of some Billing APIs mutations.
Since the underlying billing mutations already support the usage of "trialDays" parameter to enable a trial period of the app (https://shopify.dev/apps/billing/purchase-adjustments/free-trials), I would like to be able to define its value in the shopify.php config file and use it through the EnsureBilling functions as we can do for all the other billing parameters.
Type
- New feature
- Changes to existing features
Motivation
The EnsureBilling class enables setting up easily the Shopify app billing using middleware.
Since the billing API mutations used by EnsureBilling's functions already support for the trial period using the "trialDays" parameter, it would be convenient to be able to use all the mutations' native options also through EnsureBilling's functions which wrap them.
