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.
