Cumulocity Device Permissions API is one of 62 APIs that [Cumulocity](https://apis.io/providers/cumulocity/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification and an AsyncAPI event-driven specification. This API exposes 4 JSON Schema definitions. Tagged areas include Device Permissions. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, a JSON-LD context, an AsyncAPI specification, and 4 JSON Schemas.

API methods to retrieve and update device permissions assignments. Device permissions enable users to access and manipulate devices. The device permission structure is **[API:fragment_name:permission]** where: * **API** is one of the following values: OPERATION, ALARM, AUDIT, EVENT, MANAGED_OBJECT, MEASUREMENT or "*" * **fragment_name** can be the name of any fragment, for example, "c8y_Restart" or "*" * **permission** is ADMIN, READ or "*" Required permission per HTTP method: + GET - READ or "*" + PUT - ADMIN or "*" The wildcard "*" enables you to access every API and stored object regardless of the fragments that are inside it. > **⚠️ Important:** If there is no fragment in an object, for example, to read the object, you must use the wildcard "*" for the **fragment_name** part of the device permission (see the structure above). For example: `"10200":["MEASUREMENT:*:READ"]`.
