Apps can store data in the form of entity properties in the host application. Entity properties are
key-value pairs where the key is a string used to identify the property in all operations, and the
value is a JSON blob. Each host application allows properties to be stored on
entities such as Jira issues or Confluence pages, or on your app itself. Your app will need to request
the right scopes to perform operations on entity properties.
Hosted data storage is useful to Atlassian Connect developers for the following reasons:
without any need for an application server. Your data will be stored against the host application
Imports and exports are handled by the host product. Since your data is stored with the host application it is included in the host applications
backups. This means that the import process will restore your data automatically. With entity
properties you never need to worry about your data being lost or disconnected from the customer.
Conditions can be predicated on entity properties. You can configure whether a web fragment will be shown based on the value of an entity property.
The products have access to your properties. This means that you can write JQL queries based on issue entity properties, enabling users to enjoy
the power of JQL on search data that you have defined.
Users can access entity and app properties using the REST APIs. For this reason, never store
private user data or configuration information using entity properties or app properties.
