App Extensions scope and automatic deletion on uninstall

Clarified how App Extensions relate to the app that creates them and what happens to them when an app is uninstalled.

  • App ownership and scope — App Extensions are dual-scoped: each one is owned by the app registration that created it (through the app’s OAuth client_id) and stored independently in each store’s database. Only the owning API account can manage an app’s App Extensions.
  • Automatic deletion on app uninstall — BigCommerce automatically deletes a store’s App Extensions when the owning app is uninstalled, so no manual cleanup is required.
  • Uninstall callback guidance — The /uninstall callback is for cleanup within your own app; platform-registered resources such as webhooks and App Extensions are removed automatically and don’t need manual deletion.

For details, see the App Extensions overview and Single-Click App Callback Handlers.

Global Regions tutorial: clearer starting point

Thanks to user feedback, the Global Regions tutorial now explains how to reach its starting point instead of assuming you already know how to edit theme files.

  • Expanded prerequisites: the tutorial now recommends completing Create and Place a Widget first and describes both ways to edit theme files, locally with Stencil CLI or in the control panel.
  • Concrete steps: the tutorial now points to the theme’s templates/pages/ folder and spells out the stencil push command for applying local changes.

For details, see the Global Regions tutorial.

GraphQL Schema Updates

Authenticated customers can now delete a stored payment instrument through the Storefront GraphQL API. This mutation is an alpha release: the schema marks it deprecated with the reason “Alpha version. Do not use in production.”

Storefront GraphQL

  • Delete stored payment instruments: new deleteStoredPaymentInstrument mutation on the CustomerMutations type deletes a stored payment instrument for the authenticated customer.
    • Input: DeleteStoredPaymentInstrumentInput takes the token of the stored payment instrument to delete.
    • Result: DeleteStoredPaymentInstrumentResult returns an errors list of DeleteStoredPaymentInstrumentError; an empty list indicates success.

For schema details, browse the Storefront GraphQL API reference.

Removed invalid is_default filter from Get Locations

Thanks to user feedback, we’ve removed the is_default query parameter from the Get Locations endpoint reference: it was documented as a valid filter but the live API rejects it with a 422 error.

  • Removed the is_default filter parameter, which never worked against the live API
  • Other documented filters (location_id, location_code, type_id, managed_by_external_source, is_active, storefront_visibility) are unaffected and continue to work as documented

For details, see Get Locations.

  • New regions lab: Add Regions to the Product Page walks through adding a standard and a global region to the product page template.
  • New testing lab: Test Custom Regions and Config Settings provides branching steps for placing content in your custom regions in Page Builder and, optionally, in Makeswift (Beta), including built-in Stencil components and Component Styles.

Amazon EventBridge and Google Cloud Pub/Sub webhook delivery

BigCommerce webhooks can now be delivered to Amazon EventBridge and Google Cloud Pub/Sub in addition to HTTPS, giving you serverless, at-scale alternatives to hosting your own callback endpoint.

  • Amazon EventBridge — route webhook events to a serverless event bus. This delivery mechanism has graduated from closed beta to public documentation.
  • Alternative delivery mechanisms — the webhooks overview now surfaces HTTPS, Google Cloud Pub/Sub, and Amazon EventBridge as selectable delivery options.

For details, see Amazon EventBridge Webhooks and the Webhooks Overview.
