Response fields use camelCase. ### Permissions Requires the `network.read` (View networking) permission for the selected team. Resources outside that team return 404. ## OpenAPI ````yaml https://console.advinservers.com/docs/openapi.json get /servers/{server}/rdns/{ipId} openapi: 3.1.0 info: title: API reference version: 1.0.0 description: >- Use this API to manage your team's servers, networks, backups, and other resources. ## Authentication Create an API key under **API Keys** and send it as a bearer token with every request: ``` Authorization: Bearer {YOUR_API_KEY} Accept: application/json ``` Copy the key when you create it. It cannot be shown again. Revoking a key takes effect immediately. ## Permissions Give each key only the permissions it needs. Every endpoint lists the required permission. Permissions cover servers and other resources in the key's team. ## Team scope A key can access resources in the team selected when it was created. This includes servers, snapshots, backups, firewall groups, images, SSH keys, scripts, networks and addresses. Resources in other teams return `404 Not Found`. Create a separate key for each team. The key determines the team for every request. Legacy keys that had no team are assigned to the account's first owned team. ## Actions that need the panel API keys cannot do the following, even with every permission. Sign in to the panel in a browser to do them: - Create, edit or revoke API keys - Edit the IP groups that restrict API keys - End signed-in sessions - Change two-factor authentication - Change the account's email address - Accept or decline team invitations - Switch or leave a team This keeps a leaked key from widening its own access or locking you out of your account. ## Source IP restrictions A key can be restricted to one or more IP groups. Requests from other addresses are rejected. ## Requests and responses Each endpoint lists its path, query, header, and body parameters. Examples use fictional data. Single records use JSON objects. Collections use JSON arrays unless the endpoint supports pagination. Timestamps use ISO 8601 in UTC. Error responses include `message`. Validation errors also include an `errors` object for each field. Each endpoint lists its status codes. ## Audit log Every API request, including reads, is recorded in the account audit log with the key that made it. servers: - url: https://console.advinservers.com/api/v1/client security: - http: [] tags: - name: Account description: Billing contact details and account setup progress. - name: Account activity description: Actions performed in the current team by people and API keys. - name: Servers description: >- Order and list servers, read their state and resource use, open a console, and control power. - name: Server settings description: >- Rename a server, rebuild it, and change its hardware, media, resolvers and credentials. - name: Backups description: Scheduled server copies stored separately from the server. - name: Snapshots description: >- Take, restore and move server snapshots.
