# Delete Variables API removed

> Notice that the deleteVariables API has been deprecated and removed from Itential Platform, with guidance on migrating to the updateGoldenConfigTreeVersion API.

The `deleteVariables` API is now deprecated and removed from Itential Platform. You must now edit variables using Golden Config via the `updateGoldenConfigTreeVersion` API.

## Golden Config variables

Golden Configuration previously did not support full-text editing. To modify a Golden Config, you would generate a data model through the UI and then replace elements of the model with variables, which were simple `key/value` pairs. To delete these variables, you would use the `deleteVariables` API and pass in the variable names to be deleted.

With current versions of the Platform, Golden Configuration has implemented a rich-text editor and Jinja2 support, alongside support for JSON variables. All the content of JSON variables can now be updated through a single update API by modifying the JSON itself. The API that enables this is `updateGoldenConfigTreeVersion`, in which variables can be passed in.

Since the structure of how variables are stored is now JSON, the `deleteVariables` API is no longer supported and provides no functionality to the Platform. Consequently, it has been deprecated and removed.

### What should I do?

All supported versions of Configuration Manager (2022.1 and higher) use Jinja2 templates and JSON variables. The `deleteVariables` API is incompatible with Config Manager.

As a best practice, review any custom apps and adapters that might reference `deleteVariables` and update them to use the `updateGoldenConfigTreeVersion` API.
