To implement CRUD REST APIs in ABP, you create an AppService for your aggregate and expose GetAsync, GetListAsync, CreateAsync, UpdateAsync, and DeleteAsync endpoints. You then wire up permissions and validators before running the ABP app to call the endpoints.

Dynamic query filtering and pagination in ABP AppServices work by using the WhereIf extension method for conditional filtering and returning a PagedResultDto. This pattern supports sorting and paging operations safely across your domain entities.

Yes, you can use FluentValidation for DTO input validation in ABP REST APIs. The skill enforces input rules using mapped DTOs and FluentValidation to ensure data integrity before processing requests within your AppService endpoints.

ABP supports programmatic authorization checks for secure multi-tenant scenarios using its built-in authorization primitives. You wire up permissions and apply custom actions to enforce security across your multi-tenant API operations.

The best way to handle DTO mapping and error handling in ABP APIs is by enforcing patterns for mapped DTOs and utilizing FluentValidation. This approach ensures proper data transformation and validation rules across all CRUD endpoints.

You need custom actions in ABP AppServices when your API requires business logic beyond standard Create, Read, Update, and Delete operations. The skill covers optional custom actions alongside programmatic authorization checks for specialized endpoint requirements.
