How to send notification (email) to API subscribers in WSO2 Api Manager?
Is there a way to send a notification to all the API subscribers?
In the documentation there is a guide on how to do it just for a new API version, but it would be really useful to use WSO2 API Manager for other communications too
You can do this in wso2 api manager, by default you can enabled notifications so that subscribers will know that a new api version is available. If you requirement is different you can extend
org.wso2.carbon.apimgt.impl.notification.NotifierAbstract class and write a custom class

You can send an email when there is a new version of the API. Instructions are in https://docs.wso2.com/display/AM260/Enabling+Notifications
In addition to that, if you use workflows, then you can write your own implementation to send an email when workflows are completed. https://docs.wso2.com/display/AM260/Managing+Workflow+Extensions
