How to get text style properties with restful API or plugin API?

[tank666]

REST API:

Getting File Styles From Figma API

Once you’ve got the style IDs, you can get the node’s properties and values with the file nodes endpoint. For example: https://api.figma.com/v1/files/:key/nodes?ids=202:8 https://www.figma.com/developers/api#get-file-nodes-endpoint

Plugin API:
Get a list of local styles, find the desired style in the array and check its properties.

How can i import Styles from a remote lobrary into the plugin interface?

Use the getStyleByIdAsync(id) method to get the desired style data (or import styles using importStyleByKeyAsync(key), or use the REST API).
