# Add REST entity to model operation

# Add a REST entity to a model operation {#ariaid-title1}

Release version: Brazil  
Updated August 20, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Specify the REST entity that a Zero Copy Connector for ERP (Enterprise Resource Planning) model uses for a read, update, or create operation.

## Before you begin

The read, update, or create operation must be added before an entity can be added to it. For more information, see [Add an operation to a model in Zero Copy Connector for ERP](https://www.servicenow.com/docs/aImlQVW8gdvPX~CTNzODkg "Add an operation to an ERP model in Zero Copy Connector for ERP to define how the model retrieves data, writes data, or creates a new instance of the business object.").

The service tables must be populated with any services you want to add using the AI search method. REST services are read from the REST endpoint table.

For an overview of the REST API connector, see [REST API for Zero Copy Connector for ERP](https://www.servicenow.com/docs/~9t3Ms6nnLFLisImmkuSWg "Use the REST API connector to connect to any RESTful API with standardized API specification formats.").

For information about the REST API connector tables added for Zero Copy Connector for ERP, see [REST API connector tables for Zero Copy Connector for ERP](https://www.servicenow.com/docs/PviwqpjAS1PxWEvHHWxAOw "The REST API connector in Zero Copy Connector for ERP (Enterprise Resource Planning) uses these tables to store service definitions, endpoint definitions, and model metadata.").

Oracle E-Business Suite services described by WADL documents are read from the WADL service tables. For more information, see [Oracle E-Business Suite support in Zero Copy Connector for ERP](https://www.servicenow.com/docs/M_oP7cKKiQoUH1NiPNV5Tw "Zero Copy Connector for ERP reads business data from Oracle E-Business Suite (EBS) through REST services, without copying the data into ServiceNow.")  
Note:  
Many REST APIs return deeply nested JSON objects. The connector supports up to three levels of nesting in response mapping. You can define nested levels for both input parameters and output fields in the Model Manager UI.
