The following are limitations for the Salesforce Commerce Cloud connector:
+ The Contains filter is not working as expected when partitioning.
+ CDN Zones' entity doesn't support sandbox instances, and it supports only Development and production instance types. For more information, see [ https://help.salesforce.com/s/articleView?id=cc.b2c\$1embedded\$1cdn\$1overview.htm ](https://help.salesforce.com/s/articleView?id=cc.b2c_embedded_cdn_overview.htm).
+ In Salesforce Commerce Cloud, there is no API endpoint to fetch Dynamic Metadata. As a result, there is no provision to support the custom fields in the Product and Category entity.
+ Site id is a mandatory query parameter. You must pass the Site Id value through the Custom Connector Setting. For more information, see [Base URL and Request Formation ](https://developer.salesforce.com/docs/commerce/commerce-api/guide/base-url.html).
+ You can apply filters on maximum two fields (excluding Levels if present) in single API request with the combination of different operators as mentioned in the below table:
