# Update Translation Engine

`PUT /translation-engines/{translationEngineId}`

Updates a translation engine. 

It can be used to update a stand-alone translation engine or a project's translation engine. 
The identifier of a project's translation engine can be retrieved only by calling [Get Project](#/operations/GetProject) endpoint.

Pay special attention that some properties can not be changed for a project's translation engine. These include: name, description, definition.languageProcessingId, and language pairs can not be added/removed from definition.languagePairDefinitions. 

Pay special attention to how [updating](../docs/Updating-data-with-PUT.html) works.
