## API Updates and Announcement for August 3, 2023

**API**

* Added `date_created` and `date_modified` to the response body for the [Customers Group](/developer/api-reference/rest/admin/management/customers/v2) endpoint.

* Updated the webhooks blocking strategy. See the Callback retry mechanism section for more information.

**Announcement**

To help ensure platform stability, starting on August 15th, 2023, BigCommerce will begin limiting the [get a single price list record](/developer/api-reference/rest/admin/management/price-lists/price-lists-records/get-price-list-record) and [set a single price list record](/developer/api-reference/rest/admin/management/price-lists/price-lists-records/set-price-list-record) API endpoints to 40 concurrent requests each across the platform. Once we roll out the limits, API users can expect to see a 429 error code if they exceed this limit and should add appropriate error handling.

Please review the required steps below:

**Recommendations:**

* *For writes*, we recommend you implement either of our two batch price record endpoints:

Set up to 1000 price records to the [same price list](/developer/api-reference/rest/admin/management/price-lists/price-lists-records/upsert-price-list-records).

***OR***

* Set up to 1000 price records for [different price lists in a single request](/developer/api-reference/rest/admin/management/price-lists/price-lists-records/create-price-lists-records).

* *For reads*, we recommend you implement the paginated read endpoint to retrieve [multiple price records](/developer/api-reference/rest/admin/management/price-lists/price-lists-records/get-price-list-records).
