Pass their names in an event subscription's `actions`. Every account can use event subscriptions. In an account whose Macs your organization manages, they need the events capability. Service accounts can call it with the `compute:ListEventActions` permission. ## OpenAPI ````yaml /api-reference/openapi/compute.json get /compute/v2/eventactions openapi: 3.0.3 info: title: Mount Thor Compute API version: 02a4a30e3ecb description: >- Create, list, inspect and delete virtual machines and bare-metal Macs, read the image and machine-class catalogs, see your reserved capacity and your account's compute profile, report machine problems to Mount Thor, and subscribe to machine events. Service-account credentials can list, create and delete machines, read the catalogs and the compute profile, and use event subscriptions. In an account whose Macs your organization manages, they can also read a Mac and use problem reports, and every one of these only as far as the account's capabilities allow. The other compute operations are for people using the `mthr` CLI or the portal. In an account whose Macs your organization manages, an operation outside its capabilities (see Get compute profile) answers 400 `tenant_compute_customer_managed`. Mount Thor names each machine. To change a machine's class or image, delete it and create a new one. Lists return one page at a time: pass `nextPageToken` back as `pageToken` until it comes back empty. servers: - url: https://customer-api.mountthor.com security: - bearerAuth: [] paths: /compute/v2/eventactions: get: summary: List event actions description: >- Returns one page of the actions an event subscription can select, ordered by topic and then by name.

People use the session that `mthr login` stores (a token starting `mt_session_`, valid for up to 12 hours). Automation uses a service-account credential (starting `mt_sa_v1_`, valid for 90 days) from Create credential. Each operation names the permission it needs. Service accounts hold permissions through custom roles, and some operations refuse them; those operations say so. ```` This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
