# RPC create-multiple-templates

This RPC can be used to create one or more new templates.

Templates are parsed and written in parallel for better performance. If specified templates already exist, their configuration is replaced. Execution of the RPC is atomic, meaning that either all templates are successfully created or no changes are made to the UniConfig transaction.

RPC input fields:

template-name - Name of the created template.
yang-repository - YANG schema repository used to parse template configuration. The default value is latest.
template-configuration - The entire template configuration.
tags - List of template tags written on the specified paths in all created templates. A specified tag type must be prefixed with the template-tags module name based on RFC-8040 formatting of identityref.

RPC output fields:

Successful response: Returns HTTP status code 200 with no fields.
Failed response: Returns HTTP status code 400–500 and an error with the following fields:
- error-type - Error type.
- error-tag - Error tag, also determines HTTP status code.
- error-message - Description of the error that occurred when the template was applied.
- error-info - Additional information related to the error. For example, node identification, topology identification.

Mandatory fields are template-name and template-configuration.
