New Attach and Detach Operations in REST Web Services

With the new attach and detach operations, you can define or remove a relationship between two record instances. For example, you can associate a contact record instance with a partner record instance, or you can associate a file record instance with an opportunity record instance.

Currently, you can attach or detach contact records and file records only.

To attach or detach two records, you must use the record type and IDs of the record instances. For example: .../services/rest/record/v1/customer/660/!attach/contact/106

For more information, see Attach and Detach Operations.

Support for Homogeneous Batch Operations in REST Web Services

With the new homogeneous batch operations, you can add, update, delete, or upsert multiple instances of the same record type in a single REST request.

Batch operations reduce the number of network requests by processing multiple records in one request, minimizing latency and server load. This approach is useful for large-scale data imports, updates, and deletions, because it improves system performance and user experience. Batch operations in REST web services are executed asynchronously.

For more information, see Batch Operations.

New create-form Operation in REST Web Services

The create-form operation returns a record form with all fields prepopulated. This operation enables you to see all default fields and the line IDs of default lines on a record, and you can modify these values before submitting the record.

With the create-form operation, you can emulate a NetSuite UI workflow by prepopulating fields on transaction line items with values from a related record. Your REST web services application can then modify only the values it needs to before submitting the record.

For example, in the UI, when you bill a sales order, an invoice record is loaded with fields populated with values from the sales order. When loading an invoice record in REST, you can reference the related sales order record to initialize fields with values from that sales order.

For more information, see Create-form Operation.

For information about every available operation in REST web services, see SOAP Web Services and REST Web Services Operations.

New selectOptions Operation in REST Web Services

With the new selectOptions operation, you can retrieve valid select options for specific records and fields.

This operation is useful if you are creating an application UI that needs to mimic NetSuite UI logic, if the referenced record type is not yet exposed to REST web services. The selectOptions operation is also useful when the logged-in user's role doesn't have permission to the instances of the referenced record type. The selectOptions operation can return different results for the same field for different roles.

For more information, see selectOptions Operation.
