HI @OsmanWa ,
Edge Delivery Services are part of Adobe Experience Manager. As such, Edge Delivery Services and AEM Sites can co-exist on the same domain, which is a common use case for larger websites. Additionally, your AEM Sites pages can seamlessly consume content from Edge Delivery Services, and the reverse is also true.
In your case does EDS and AEM exist on same domain? If yes then you can try to integrate salesforce with AEM and then can redirect the form response.
