# Rename an iMessage group or change its photo

`PATCH /v1/imessage/groups/{conversationId}`

One change per call: either `name` or `photoUrl` (an empty `photoUrl` removes the photo). Applied asynchronously by the provider; a rename is mirrored on the inbox conversation right away.

## Path parameters

- `conversationId` string, required

## Request body

- object
  - `accountId` string, required
  - `name` string
  - `photoUrl` string — Public HTTPS image URL; empty string removes the photo

## Response `200`

Change accepted

- object
  - `success` boolean
  - `conversationId` string

## Other responses

- `400` — Bad request, or the conversation is not a group thread
- `401` — Unauthorized
- `404` — Account or conversation not found

## Changes

- **2026-09-21** `339f59df69dd` — 1 info
  - endpoint added
