# Dxplaination of Interface Call Request

Get information about all three level categories and their qualifications Note: This interface pulls the full amount of third-level category data, and the data back packet size is about 2MB. Therefore, merchants should make their own caches, and do not call them frequently (there is a strict frequency limit). The data in this category does not change frequency, and merchants are recommended to call once a day to update their own caching.

If the category qualification is required, a qualification application must be made through the category eligibility application interface before adding a product; If the category qualification is not required, the category is automatically owned, no application is required, and if the category is still invoked, the error 1050011 will be reported; If the product credential is required, bring the commodities credential field with you when you add a product. Access category audit corrections are required to obtain audit results.
