Update Document Parameters

Type PUT

https://api.ai21.com/studio/v1/library/files/fileId

Updates the specified parameters of a specific document in the user's library. This operation currently supports updating the publicUrl and labels parameters.

This operation will overwrite the existing values of the parameters. If you wish to add new labels without removing the existing ones, you must include the existing labels along with the new labels in the labels parameter.

For instance, if the existing labels are "Label A" and "Label B", and you wish to add "New Label C" and "New Label D", you must set "labels": ["Label A", "Label B", "New Label C", "New Label D"]. If you set "labels": ["New Label C", "New Label D"], the labels "Label A" and "Label B" will be removed.
