Hide node created messages programmatically I'm trying to the node created messages for a certain content type, but I can't use Disable Messages because it has a conflict the Commerce Add to Cart Confirmation module.

All the other methods (like the ones here) I've found either hide all status messages, or hide all status messages after a content type is created, which are inappropriate for me since I'm using rules to show a messages after a node is created, but I need to hide the default "__________ has been created" message, and I appreciate any help you can offer me.
drupal_set_message is not hookable. But the message you want removed comes from node_form_submit, so you can get rid of it using hook_form_FORM_ID_alter on node_form. Either replace node_form_submit as form's submit handler with it's clone, sans messages, or set second handler that will remove what you want removed from $_SESSION['messages'][$type].
