# Associate campaigns

`POST /v1/accounts/{accountId}/conversion-destinations/{destinationId}/associations`

Associate one or more campaigns with this conversion rule. Returns a
per-campaign success/failure result so callers can retry only the
rows that failed (e.g. wrong campaign type for the rule's objective).

## Path parameters

- `accountId` string, required
- `destinationId` string, required

## Request body

- object
  - `adAccountId` string, required
  - `campaignIds` string[], required

## Response `200`

Per-campaign batch result. Status is 200 even when some rows
failed. Inspect `failed[]` for details. Inputs that fail local
URN validation are bucketed into `failed` without ever hitting
LinkedIn.

- object
  - `platform` 'linkedinads'
  - `succeeded` string[] — Numeric campaign IDs that were successfully associated.
  - `failed` object[]
    - `campaignId` string
    - `reason` string

## Other responses

- `400` — Invalid body.
- `401` — Unauthorized
- `403` — Ads add-on or LinkedIn reconnect required.
- `404` — The account or requested resource was not found or is not accessible. An account ID may have been disconnected and removed. Read GET /v1/accounts for current account IDs.
- `405` — Platform does not support associations.
- `409` — The account exists but is inactive or needs reconnection. Reconnect it, then read GET /v1/accounts for its current account ID before retrying. Code: ads_connection_required.
- `429` — LinkedIn rate limit hit. Retry with backoff.
