iZooto push API to send notifications to subscribers allows you to send notifications to an individual subscriber against a subscriber ID, to multiple subscriber IDs, to a group of subscribers bucketed using properties, to an audience defined with 'Audience Builder' on the panel and to all.
Before you start using these APIs, please ensure that you have the API key for the website with you. You can place a request for the same from iZooto Panel from Settings > Get API Key > Request API key.
You'll receive an API key over email as soon as your request gets approved. It will also be visible under Get API key.
