Role Policies (legacy)

📘

Enterprise Feature

Role policies allow developers to link an Application User role to a particular schema, and define the shape of the resources they can interact with. For example, a role for a device engineer that only allows them to create Thngs that have a pre-defined set of fields, and guarantee that all required properties is present.

If multiple schemas are required to be associated with a role, this can be easily achieved by creating multiple policies for that same role.

📘

Note

Once created, policies cannot be updated. You must delete the original policy and create a new one with the new data.
