## Relationships

### Object Relationships

*   `activity` — The thread activity this reaction belongs to

## Query Examples

### List Reactions for an Activity

```
query GetActivityReactions($activityId: uuid!) {  thread_activity_reaction(    where: { activityId: { _eq: $activityId } }    order_by: { createdAt: asc }  ) {    id    shortcode    userId    createdAt  }}
```

## Mutation Examples

### Add a Reaction

```
mutation CreateActivityReaction {  insert_thread_activity_reaction_one(    object: { activityId: "activity-id", shortcode: "👍" }  ) {    id    shortcode    createdAt  }}
```

### Remove a Reaction

```
mutation DeleteActivityReaction {  delete_thread_activity_reaction_by_pk(id: "reaction-id") {    id    shortcode  }}
```

## Permissions

Reaction access is controlled based on organization membership:

*   **View** — All authenticated users can view reactions
*   **Create** — Organization members (with Member, Admin, or Owner role) can add reactions. The `userId` is automatically set to the authenticated user
*   **Delete** — Users can only remove their own reactions

Each member can add multiple different emoji reactions to an activity, but duplicate emoji reactions from the same member are prevented. Reactions are typically displayed as emoji counts per activity and can be used for quick polls or sentiment tracking.
