API creation: my action is not found (only on Linux server)
Even i have faced such problems many times in past. But i do some work around and fix it. What i would do


rename file ImportData.php to WD2.php
move WD2.php to org.civicrmitalia.washdog\api\v3\
Use lower case as function name. eg civicrm_api3_w_d2_importdata($params)
