# Remove reaction

`DELETE /v1/inbox/conversations/{conversationId}/messages/{messageId}/reactions`

Remove a reaction from a message. Platform support:
- Telegram: Send empty reaction array to clear
- WhatsApp: Send empty emoji to remove
- Instagram and Facebook Messenger: Sends Meta's `unreact` action; the emoji does not need to be repeated
- Slack: Removes the reaction we previously sent on that message
- All others: Returns 400 (not supported)

## Path parameters

- `conversationId` string, required
- `messageId` string, required

## Query parameters

- `accountId` string, required

## Response `200`

The platform accepted the removal request. This does not guarantee a reaction was removed: the platform never confirms what it acted on, and a reaction placed by the other participant cannot be removed (platform rule). Check `fromMe` on GET /messages to know who placed a reaction.

- object
  - `success` boolean
  - `messageId` string — The Zernio message ID the removal was resolved against
  - `platformMessageId` string — The platform message ID the removal was sent for

## Other responses

- `400` — Platform does not support reactions or invalid request
- `401` — Unauthorized
- `403` — Inbox addon required
- `404` — Account, conversation or message not found (message_not_found when messageId does not resolve to a message in this conversation)

  - added the optional property `platformMessageId` to the response with the `200` status
