List folders (`contactList`/`companyList`) resolve by id alone; pass `?type=campaign` or `?type=agent` to rename a campaign or agent folder, which live in their own services. The new name must be unused among folders of the same kind (409 FOLDER_NAME_TAKEN). The response is the rename echo — the folder's id and its new name. Errors: - `404` `FOLDER_NOT_FOUND` — No folder with that id (of the routed kind) belongs to the token owner. - `409` `FOLDER_NAME_TAKEN` — Another folder of the same kind already has that name. - `400` `INVALID_REQUEST` — campaign/agent kinds only: the owning service rejected the request. - `422` `VALIDATION_FAILED` — folderId not a 24-hex id, name missing/blank/over 120 characters, or type outside the enum. - `429` `RATE_LIMITED` — The lists rate bucket (120 requests/minute, 10,000/day per token owner) is exhausted, or the owning service (campaign/agent folders) refused the call. Requires one of the following token scopes: lists. ## OpenAPI ````yaml /openapi.json patch /business/folders/{folderId} openapi: 3.1.0 info: title: Fuse Business API version: 1.0.0 description: >- External API for lists, campaigns, prospect search and contacts.
