They are used to trigger workflows, and enable you to send notifications to subscribers based on their actions. externalDocs: url: https://docs.novu.co/workflows - name: Subscribers description: >- A subscriber in Novu represents someone who should receive a message. A subscriber's profile information contains important attributes about the subscriber that will be used in messages (name, email). The subscriber object can contain other key-value pairs that can be used to further personalize your messages. externalDocs: url: https://docs.novu.co/subscribers/subscribers - name: Topics description: >- Topics are a way to group subscribers together so that they can be notified of events at once. A topic is identified by a custom key. This can be helpful for things like sending out marketing emails or notifying users of new features. Topics can also be used to send notifications to the subscribers who have been grouped together based on their interests, location, activities and much more. externalDocs: url: https://docs.novu.co/subscribers/topics - name: Integrations description: >- With the help of the Integration Store, you can easily integrate your favorite delivery provider. During the runtime of the API, the Integrations Store is responsible for storing the configurations of all the providers. externalDocs: url: https://docs.novu.co/platform/integrations/overview - name: Workflows description: >- All notifications are sent via a workflow. Each workflow acts as a container for the logic and blueprint that are associated with a type of notification in your system. externalDocs: url: https://docs.novu.co/workflows - name: Messages description: >- A message in Novu represents a notification delivered to a recipient on a particular channel. Messages contain information about the request that triggered its delivery, a view of the data sent to the recipient, and a timeline of its lifecycle events.
