# Set or Update Label for Attribute Set

`PUT /attribute/label/{user_token}/{endpoint_token}/{attr_set_token}`

This **PUT** endpoint sets or updates a human-readable label for a given `attr_set_token`.<br>
Labels help identify the context of the attribute set — for example, assigning a label like "JPMorgan Chase" to represent attributes linked to that specific destination or financial institution.<br>
Provide the `attr_set_token` and `endpoint_toke` as a path parameter and the desired `label` in the request body.<br>
If a label already exists for the attribute set, it will be overwritten.
