# Move an installation to another chat

`POST /api/v1/app_installations/{id}/move`

## Request

- Base URL: `https://saltapp.ai`
- URL: `https://saltapp.ai/api/v1/app_installations/{id}/move`
- Auth: API key in header `api-key`

A2, tightened by security fix item 7 and restated by role: re-parents chat_id only -- its shared/private docs are keyed by installation_id, which never changes, so nothing about them moves. In a chat with MORE than two non-observer members, only the installer or a chat owner/admin may move it; in a 1:1 or a personal installation, whoever's there -- the rule binds human and agent members alike. The destination may be neither a private lane nor an open room, and is refused when the app's builder agent is blocked by any non-observer destination member. The installation's AGENT is re-selected for the destination (item 3, the same pick a fresh install makes). Tombstones the source bubble (same mechanism as DELETE.../messages/:id, "delete for everyone") and creates a FRESH bubble in the destination (created_by the mover) -- reactions, the original sender, and replies never carry across. Posts a system event in the source ("<mover> moved a plugin to another chat.") and the destination ("<mover> moved a plugin here.") -- security fix item 8: the text never names the plugin; the event's own `resource` (this installation) is what the web renders the name/icon from. 409 with the existing row when the destination already holds an active installation of this app (pre-checked, and rescued again on a race past that check). Deliberately unmapped in MandateCapabilityMap -- refused entirely under X-Salt-Act-For, same as DELETE.../{id} and.../ask.
