# Like a LinkedIn comment

`POST /like/linkedin/comment`

Reacts to a LinkedIn comment. Use the commentUrn returned by /collect/linkedin/comments directly — do NOT reconstruct it from hash fields.

## Request body

- object
  - `commentUrn` string, required — LinkedIn comment URN (e.g., 'urn:li:comment:(activity:7399026485694537728,7399230513867026433)')
  - `reactionType` 'LIKE' | 'LOVE' | 'CELEBRATE' | 'SUPPORT' | 'FUNNY' | 'INSIGHTFUL' — Reaction type (default: LIKE)
  - `campaignSlug` string — Campaign identifier for deduplication. Dedup by commentUrn automatically.
  - `actionSlug` string — Deprecated. Use campaignSlug only.

## Response `200`

Comment liked successfully

- object
  - `success` true, required
  - `resourceKey` string — Resource key of the created reaction
  - `duplicate` boolean — True if this action was already executed for the given campaignSlug + target.
  - `creditsUsed` integer, required — Credits consumed by this call (0 for free endpoints, cached results, or duplicates).
  - `retryAfter` integer, required — Seconds to wait before making another call of the same type. 0 means no wait needed.

## Other responses

- `400` — The server cannot or will not process the request due to something that is perceived to be a client error.
- `401` — Although HTTP specifies "unauthorized", this response means "unauthenticated". Authenticate to continue. NOTE: 401 is also returned with code "linkedin_not_connected" when the caller IS authenticated but has no connected LinkedIn account — connect LinkedIn (not re-authenticate) to continue.
- `403` — The client does not have access rights to the content.
- `404` — The server cannot find the requested resource.
- `409` — The request conflicts with the current state of the server.
- `410` — The requested content has been permanently deleted from the server.
- `422` — The request was well-formed but was unable to be followed due to semantic errors.
- `429` — Rate limit exceeded. Read error.retryAfter for the wait time in seconds.
- `500` — The server encountered a situation it does not know how to handle.
- `502` — LinkedIn returned a server error or the proxy connection failed. Retry after a few seconds.
- `503` — Proxy capacity temporarily exceeded. Retry after a few seconds.
