# Go Offline

`POST /mode/offline`

This function is used to put UTG/Commerce Engine into offline mode. UTG/Commerce Engine will be configured to set a maximum duration for how long it will stay in offline mode in order to prevent UTG/Commerce Engine from staying offline indefinitely if the Interface Vendor does not send the go online request. 

Note: To utilize this feature with UTG, you must be running UTG version 3080 or later. UTG can be configured to disable this feature, which will prevent the API request from putting UTG into offline mode.

**Integration Methods:**
- Locally Installed UTG
- Commerce Engine For On Premise

See the [Integration Methods](/guides/quickstart#integration-methods) and [URLs Section](/guides/quickstart#urls) sections of the Development Quick Start guide for details regarding each processing option.
