New inventoryPolicy argument for billing mutations

As of 2025-01, we’ve introduced an optional ‘inventoryPolicy’ argument for mutations that create billing attempts. This feature allows developers to override a merchant's inventory settings during the billing process. Regardless of whether a merchant's settings permit or restrict overselling, you can now specify your preferred inventory policy when initiating billing attempts. This flexibility ensures that your billing processes align with your specific inventory management needs.

The ‘inventoryPolicy’ argument can be used with the following billing attempt mutations:

• subscriptionBillingAttemptCreate
• subscriptionBillingCycleCharge
• subscriptionBillingCycleBulkCharge.

For more detailed information on how to implement the inventoryPolicy argument, visit the Shopify.dev documentation.
