Add or remove an emoji reaction on a LinkedIn message. Set react=false to remove the reaction. message_urn is the message_urn returned by list_conversation_messages (e.g. urn:li:msg_message:(urn:li:fsd_profile:…,123456789)). emoji is a Unicode emoji character (e.g. 👍, ❤️). Pass conversation_linkedin_id to also mark the conversation as read.
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| account_id | integer | yes | Reach id of the LinkedIn account to act on, from list_accounts. |
| message_urn | string | yes | Full message URN to react to. |
| emoji | string | yes | Unicode emoji character (e.g. 👍, ❤️). |
| react | boolean | no | True to add the reaction, False to remove it. |
| conversation_linkedin_id | string | no | Conversation ID — when provided the conversation is marked as read. |
| idempotency_key | string | no | Optional. A key you choose (a UUID is fine) that names this exact call. If you retry with the same key and the same arguments, the first call's result is returned and nothing is done twice on LinkedIn. Reusing a key with different arguments is refused. Keys expire after 24 hours. |
