# BuildObject

Trains Media Server to recognize an object.

You can only run this action after creating an object (using the action NewObject) and adding suitable images (using the action AddObjectImages).

Type: asynchronous

Parameter | Description | Required
--- | --- | ---
`database` | The name of the database that contains the object. | Yes
`identifier` | The identifier of the object that you want to train Media Server to recognize. | Yes
`numparallel` | The maximum number of threads to use to complete the training (default 1), subject to the limit specified by MaxNumParallel. | No

## Example

    /action=BuildObject&database=CompanyLogos&identifier=HewlettPackard

## Response

This action is asynchronous, so Media Server always returns success accompanied by a token. You can use this token with the QueueInfo action to retrieve the status of your request.
