# Unblock User

> Unblock a user by their ID

Removes the block edge from the acting user (the blocker) to the specified user (the target). The barrier lifts immediately.

Unblocking is **idempotent** — unblocking a user who isn't blocked is a success no-op. Nothing that the block tore down is restored: removed follows and connections stay gone and the two users must re-establish them from scratch. A previously frozen 1:1 conversation becomes usable again (the conversation record still exists).

<Note>
  **Requires the `moderation` bundle.** A project without the moderation bundle returns `403 database/tables-not-available`. See [Bundles](/bundles).
</Note>

## Path Parameters

<ParamField path="userId" type="string" required>
  The Sublay user ID (UUID) of the user to unblock (the target).
</ParamField>

## Query Parameters

<ParamField query="actingUserId" type="string">
  The user performing the unblock (the blocker). Only service/master keys may supply an `actingUserId` other than the caller's own; with a user token the blocker is derived from the token.
</ParamField>

## Response

On success, returns HTTP `204` with no body.
