create_linkedin_image_campaign instead.
DO NOT USE for video ads → use create_linkedin_video_campaign instead.
DO NOT USE for text ads → use create_linkedin_text_campaign instead.
REQUIRED: Either campaign_group_name (creates new group) or campaign_group_id (adds to existing group).
IMPORTANT: This creates the campaign with 1 creative (Variation 1). Campaign is created in PAUSED status.
Carousel Specifications:
- 2-10 cards required (3-5 is the sweet spot)
- All images must be 1080x1080 (1:1 aspect ratio)
- Each card has: image, headline (max 45 chars), landing page URL
- Introductory text max: 255 characters
- campaign_name, daily_budget, organization_id
- introductory_text (up to 255 chars), landing_page_url (overall)
- cards: Array of 2-10 cards, each with image (urn or url), headline, landing_page_url
- locations (targeting)
- campaign_group_name OR campaign_group_id
- This tool created 1 campaign + 1 creative. Campaign Group ID is returned.
- To add MORE carousel creatives (A/B test text): use
add_linkedin_carousel_creativewith the campaign_id - To add MORE campaigns (different audience): use
add_linkedin_campaign_to_groupwith the campaign_group_id - NEVER call this create tool again without campaign_group_id — that creates a SEPARATE campaign group

name: ADSMCP Support
description: >-
REST endpoints for every ADSMCP tool. Same surface as the MCP server, over
plain HTTP for consumers that can't speak SSE (n8n, Zapier, Make, curl, any
language's HTTP client).
## Envelope
Every request wraps tool-specific input in an `arguments` object:
```json
{ "arguments": { <tool-specific fields> } }
```
Every response wraps the result in either a success envelope (`success:
true`, `data: {...}`) or an error envelope (`success: false`, `error:
"..."`, `is_error: true`).
## Authentication
Pass your API key as `Authorization: Bearer sk_live_...` on every request.
Generate keys at https://adsmcp.si/dashboard/api-tokens.
## Quota & billing
Every successful billable call decrements your monthly tool-call allowance.
The current counter is attached to every 200 response under `data.quota`:
```json
"quota": { "used": 42, "limit": 150, "tier": "plus", "period_end":
"2026-05-01" }
```
When the limit is hit, the API returns HTTP 402 with a full `quota` block
including `upgrade_url`. Read-only diagnostic tools (`get_usage_status`,
`list_connected_accounts`, `get_connections_status`) are exempt and never
consume quota.
## Idempotency
Write operations accept an `Idempotency-Key: <uuid>` header. A repeated call
with the same key returns the cached result rather than executing twice.
**Strongly recommended for n8n, Zapier, and any retry-prone client** — it
prevents duplicate campaigns when networks misbehave. Generate a fresh UUID
per logical operation (not per retry).
## Multi-account users
Customers with multiple connected accounts on the same platform (e.g. an
agency with 10 Meta ad accounts) must specify which account to use via
`ad_account_id`, `customer_id`, `advertiser_id`, or `account_id` depending
on the platform. Omitting it returns HTTP 400 with a list of valid account
IDs. See `list_connected_accounts` to discover available IDs.
## HTTP status codes
- `200` — success (parse `data`)
- `400` — tool-level error (surface `error` to users)
- `401` — bad/missing API key
- `402` — ADSMCP quota exhausted
- `404` — unknown tool name
- `429` — upstream ad platform rate-limited us (Meta/Google/etc.) — retry
with backoff
- `500` — server error, report to support
## Streaming
This endpoint is plain request-response JSON. There is **no SSE, no chunked
streaming**. Safe to use from n8n Cloud's HTTP Request node, Zapier
Webhooks, Make HTTP module, curl, and every mainstream HTTP library.

summary: Create LinkedIn Carousel Campaign
description: >-
**USE THIS TOOL WHEN:** User wants to create a LinkedIn CAROUSEL ad
campaign (2-10 swipeable image cards).
**DO NOT USE for image ads** → use `create_linkedin_image_campaign`
instead.
**DO NOT USE for video ads** → use `create_linkedin_video_campaign`
instead.
**DO NOT USE for text ads** → use `create_linkedin_text_campaign`
instead.
**REQUIRED:** Either `campaign_group_name` (creates new group) or
`campaign_group_id` (adds to existing group).
IMPORTANT: This creates the campaign with 1 creative (Variation 1).
Campaign is created in PAUSED status.
Carousel Specifications:
- 2-10 cards required (3-5 is the sweet spot)
- All images must be 1080x1080 (1:1 aspect ratio)
- Each card has: image, headline (max 45 chars), landing page URL
- Introductory text max: 255 characters
Required Parameters:
- campaign_name, daily_budget, organization_id
- introductory_text (up to 255 chars), landing_page_url (overall)
- cards: Array of 2-10 cards, each with image (urn or url), headline,
landing_page_url
- locations (targeting)
- campaign_group_name OR campaign_group_id
Default Objective: WEBSITE_VISIT
AD POLICY: NEVER use "LinkedIn" in ad copy. NEVER mention competitor
platforms.
**After Creation — IMPORTANT:**
- This tool created 1 campaign + 1 creative. Campaign Group ID is
returned.
- To add MORE carousel creatives (A/B test text): use
`add_linkedin_carousel_creative` with the campaign_id
- To add MORE campaigns (different audience): use
`add_linkedin_campaign_to_group` with the campaign_group_id
- NEVER call this create tool again without campaign_group_id — that
creates a SEPARATE campaign group
Execution time: 15-60 seconds (includes image uploads)
operationId: execute_create_linkedin_carousel_campaign
parameters:

Client-generated UUID to make writes idempotent. Strongly
