You may be able to improve performance by coding REST API calls in a way that controls the size and number of responses. There are specific query parameters provided in support of this, and we recommend that use them wherever they are applicable. Avoid using multiple endpoint calls where a bulk option exists, for example, fetching data per SKU instead of per product, which for some endpoints would give data for all child SKUs of that product. As discussed in the section that follows, consider a review of your code.
