# Reactions on LinkedIn messages

> See who reacted to your LinkedIn messages, and use a reaction in a campaign.

When someone reacts to a LinkedIn message (a thumbs up, a heart, a laugh...), Kerux shows it in the inbox and on the contact's history, like LinkedIn does.

## Where you see reactions

* **In the inbox**: small emoji under the message. Hover over one (or tap it on a phone) to see who reacted: "They reacted 👍" or "You reacted ❤️" (your own reactions, made on LinkedIn, have a highlighted outline). A number shows when several people reacted with the same emoji.
* **On the contact's history**: "Reacted 👍 to your message", with the first words of the message. If they take the reaction back, the history says "Took back a reaction to your message" and the emoji leaves the inbox.

Reactions show up shortly after they happen on LinkedIn.

## A reaction is not a reply

A reaction counts as **engagement** (it adds to the contact's [engagement score](/help/leads/routing-and-engagement.md)), never as a reply: a campaign that stops on replies keeps going, the conversation doesn't show as unread, and reply types aren't used. Use a reaction in a campaign in two ways:

* **If they react** step (Automations): after a message, it waits the time you set (2 days by default). **Reacted** when they react to one of the campaign's LinkedIn messages in that time (or already did), **No reaction** when the wait ends without one. A reply always wins: with **Stop when the contact replies** on (the default: the **Replies** switch in the campaign's **Settings**) the contact leaves the campaign as with any reply; otherwise it follows **Replied**, if you add it. In **Add a step** it's under **Steps > Timing** and **Conditions > Contact actions** (**Reacted to your LinkedIn message**). See [Steps](/help/campaigns/steps.md).
* **Reacted to a LinkedIn message** (a Kerux event): a contact's reaction starts another campaign, for example to send your booking link. Pick **Any** reaction or one emoji. The campaign's steps get the emoji as **Reaction (emoji)** (`{{trigger.reaction}}`). See [Start a campaign from what happens in Kerux](/help/campaigns/kerux-triggers.md).

There's a ready-made campaign for it: **Reacted to my message: send my booking link** in **Campaigns > New campaign**. It writes your link with the workspace variable `{{workspace.vars.calendar_link}}`: set it in **Integrations > Variables**, or the message waits for it instead of going out without the link.

## From the API and webhooks

`GET /v1/conversations/{id}/messages` returns each message's `reactions` (emoji, count, and `mine` for your own). The webhook event `linkedin.message_reacted` fires when a contact reacts to one of your messages, and Event Rules can listen to **The contact reacts to a message**. See [Webhooks](/help/developers/webhooks.md).
