## API Updates for June 13, 2024

**API**

* We added the `origin_channel_id` to the list of read-only fields in the [Customers V3](/developer/api-reference/rest/admin/management/customers) API. This field is set upon customer creation and cannot be updated afterward.

* The newly released [Tax Settings API](/developer/api-reference/rest/admin/management/tax)’s `document_submission_strategy` field lets you choose when to submit tax documents to third-party tax providers.

* We’re happy to announce the new `store/modifier/updated` [webhook](/developer/docs/integrations/webhooks/event-reference) and the `store/option/updated` [webhook](/developer/docs/integrations/webhooks/event-reference), which fires when you update a modifier or variant option globally or for a channel.

* The new `store/product/updated` [webhook](/developer/docs/integrations/webhooks/event-reference) fires when you update the product for a channel.

**Announcements**

* The bigcommerce/docs repo now contains the OpenAPI Specification files for promotions, inventory, locations, and other newer API features!

* The narrative documents’ source file structure in the bigcommerce/docs repo now matches the Dev Center URLs. Finding the document you want to modify is now easier than ever.

* The API reference source file restructure in the bigcommerce/reference repo is in progress. After completion, we will give all API client maintainers enough notice to reset your references.

**Bug Fix**

* Corrected the request body for the [Create Cart redirect URL](/developer/api-reference/rest/admin/management/carts/redirects/create-cart-redirect-url) endpoint. Now, the request body will no longer throw errors.
