# Adds explicit contributors to the specified filter.

POST https://api.awork.com/api/v1/filters/{filterId}/contributors
Content-Type: application/json

Adding filter contributors grants explicit access to the filter with the specified access levels.
Existing explicit contributors are ignored and therefore not recreated.
The filter creator cannot be added as an explicit contributor because ownership is handled implicitly.The user must have at least `manage` permissions for the specified filter.
