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: Add LinkedIn Campaign To Group
description: >-
**USE THIS TOOL WHEN:** User wants to add a new campaign with DIFFERENT
targeting/audience to an EXISTING campaign group. This is the LinkedIn
equivalent of Meta's add_ad_set.
LinkedIn hierarchy: Campaign Group → Campaign → Creative.
- Different audiences = different Campaigns in the SAME Campaign Group.
- Different creatives = different Creatives in the SAME Campaign.
**Common scenarios:**
- Audience testing: Same ad format, different targeting per campaign
- Geographic split: Same creative, different locations per campaign
- Multi-market: Same product, different countries
- Scaling: Adding new audiences to existing campaign group
**CRITICAL:** Each create_linkedin_*_campaign creates a new Campaign
Group (unless campaign_group_id is passed).
To add more campaigns to the SAME group, you MUST use this tool or pass
campaign_group_id to create tools.
NEVER call create_linkedin_*_campaign without campaign_group_id for the
same group.
**KEY DISTINCTION:**
- Different audience/targeting → use THIS tool (new campaign in same
group)
- Different copy/creative, same audience → use add_linkedin_creative /
add_linkedin_video_creative instead
**Supports all 4 ad types:** image, video, carousel, text.
Each campaign has INDEPENDENT: targeting, budget, schedule.
Shared from campaign group: objective, group name.
**Workflow:**
1. Create initial campaign → get campaign_group_id + campaign_id
2. Call this tool with campaign_group_id for each additional audience
3. Use add_linkedin_creative to add more creatives within any campaign
Execution time: 15-120 seconds (depends on ad type)
operationId: execute_add_linkedin_campaign_to_group
parameters:
- description: >-
Client-generated UUID to make writes idempotent. Strongly
recommended for write tools. A repeat call with the same key returns
the cached result instead of re-executing. Example:
