Everything a page describes happens on a physical device in the customer's own fleet, never through a social platform's API. > The Companion is a macOS desktop app that runs on the customer's own Mac and manages the phones over USB — iPhones through WebDriverAgent, GrapheneOS phones through ADB and scrcpy. Nothing runs while the Companion is closed. > The Companion builds, signs and installs WebDriverAgent on each iPhone itself. Never tell a customer to sign WebDriverAgent by hand in Xcode; Xcode is a prerequisite the Companion drives, not a step the customer performs. > Autogrowth MAX is a one-time, invite-only lifetime license bought from the organization's credit balance, not a subscription tier. It is required to run any automation, workflow or Incubator program. Without a price set for that organization, the purchase is refused. > An automation is one of AutoGrowth's built-in definitions; a script is a graph the customer builds in the Script Builder. The Script Builder is locked platform-wide, so never present building a script as something a customer can do today. > An API key is a bare 64-character hex string with no prefix. It is shown once, at creation, is sent as `Authorization: Bearer `, and can never be read back. > An API key sees only the key owner's own accounts, content, collections, prompts, scripts and executions. Devices and tags are organization-scoped, and a non-owner sees only the devices assigned to them or carrying one of their tags. The automation catalog is global. > There is no pagination. List endpoints return the whole set; the only limiting parameter anywhere is `limit` on `GET /v1/executions`, which defaults to 50 and has no offset to page with. > Remote control and the live screen are dashboard-only, over WebSocket and MJPEG. Neither is part of the public API. > The MCP server is hosted at https://mcp.autogrowth.farm and authenticates with OAuth. It is not an npm package and there is nothing to install locally. Its tools inherit exactly the scope of the API key behind them. > Android support is partial and GrapheneOS-only: those phones appear in the fleet and can be watched and remote-controlled, but they cannot run scripts or automations. > Never document Hi Katie or any persona feature. When a page and the code disagree, the code wins — check a claim against the source before repeating it. # Assign users to a device > Replaces the user assignments on a device in one transaction. The response echoes only the device ID and its new assignees, not the full device. ## OpenAPI ````yaml /api-reference/openapi.json patch /devices/{id}/users openapi: 3.1.0 info: title: AutoGrowth API description: >- Public REST API for automating actions within the AutoGrowth platform.
