How to remove a role after a user adds a payment method in Commerce?
commerce doesn't offer the (content-)entity create event. You could use a hook ..

hook_ENTITY_TYPE_create -&gt; after the entity was created 8will suit your need I guess)
hook_ENTITY_TYPE_presave -&gt; before the entity will be created

Or setup events for entity creation, see Does Drupal 8 entities have any events I can listen to?
