# Call ads.create_pmax_campaign

`POST /api/v1/tools/ads.create_pmax_campaign`

## Request

- Base URL: `https://app.goosybear.ai`
- URL: `https://app.goosybear.ai/api/v1/tools/ads.create_pmax_campaign`
- Auth: HTTP bearer

Prepare a Google Ads Performance Max campaign — 'set up a performance max campaign', 'create a pmax campaign from our brand'. Create a Google Ads PERFORMANCE MAX campaign for this brand, with the asset group built from its saved words and pictures, and report the asset counts Google read back. Call it on the ask: it raises the approval card, which is the operator's confirmation, and nothing is created unless they approve it there. ⚠️ It is then created PAUSED and stays paused — you cannot start it, and nothing here spends the budget. Say so when you report it. Two saved things decide whether it can run at all: a bidding choice Performance Max accepts, and the Performance Max assets — `ads.google_settings` reports exactly which are missing. If missing_required_field_types comes back non-empty, say so: the campaign exists but the group cannot serve yet. Reuse the same idempotency_key on a retry — a fresh key mints a second campaign. Not for a Smart campaign — that is `ads.create_smart_campaign`. Over the API it answers in two calls: without confirmation_id it proposes — says what would happen, returns a confirmation_id and changes, spends and sends nothing; the same arguments again with that confirmation_id, on a member's own API key, do it.

Every result names the workspace it ran in. Say which workspace the answer is about. When the account has more than one workspace and none is selected, this tool refuses with `workspace_ambiguous` and lists the choices — offer them, never pick one.

## Headers

- `x-request-id` string
- `Idempotency-Key` string, required

## Request body

- object
  - `name` string, required: What the campaign is called.
  - `daily_budget_usd_cents` integer, required: The DAILY budget, in cents. 5000 is fifty dollars a day.
  - `start_at` string, nullable: ISO-8601, optional.
  - `end_at` string, nullable: ISO-8601, optional.
  - `idempotency_key` string: Deprecated on REST: send the `Idempotency-Key` header instead. Still accepted until 2026-12-31; if both are sent they must match.
  - `confirmation_id` string, uuid: Omit to propose: the first call says what would happen, returns a confirmation_id and changes nothing. To go ahead, send the same arguments again with that confirmation_id, on a member's own API key; a service account's key can propose but never confirm.
  - `workspace` string: Which workspace to run in — its slug. Omit to use your default. With more than one reachable workspace and no default, the call is refused and the choices are listed.

## Response `200`

The call was admitted and dispatched. `ok` says whether the tool succeeded — a refusal the tool itself produced is still a 200, exactly as it is a successful JSON-RPC result over MCP.

- union
  - object: The tool ran and answered.
    - `ok` true, required
    - `state` 'confirmation_required'
    - `confirmation_id` string, uuid
    - `expires_in_seconds` integer
    - `request_summary` string: What will happen, in one sentence, for a person to approve before confirming.
    - `resource_name` string
    - `id` string
    - `name` string

    - `asset_counts_by_field_type` object
    - `missing_required_field_types` string[]
    - `applied_readback` string
    - `workspace` string, required: The slug of the workspace this call ran in.
    - `working_in` object, required: Which workspace this call ran in, and how that was decided. Present on every workspace-scoped result.
      - `label` string, required: The chip words — e.g. "working in: Acme Main".
      - `note` string, required: Why this workspace — e.g. "your default", "this call only".
      - `workspace` string, required: The resolved workspace's slug.
      - `source` 'call-override' | 'key-pin' | 'stored-default' | 'sole-reachable', required: Which rung of the R7 precedence resolved the workspace.
  - ToolRefusal: A call that was admitted and dispatched, and did not succeed.
    - `ok` false, required
    - `code` string, required: The typed reason — e.g. `workspace_ambiguous`, `invalid_arguments`, or the tool's own failure code.
    - `message` string, required: A sentence a person can act on.
    - `workspaces` string[]: On a workspace refusal: the slugs this key may pass as `workspace`.
    - `issues` object[]: On `invalid_arguments`: which fields failed, and why.
      - `path` string, required
      - `message` string, required
    - `path` string: On an authoring refusal: where in your call's input it points, e.g. `steps.<key>.params.<field>`.
    - `fix` string: On an authoring refusal: the change to your call that would pass.
    - `instruction` string: On an authoring refusal: what to do next with it.

## Other responses

- `400`: The request could not be used: the body is present but not a JSON object (`tenant_api.malformed_body`); it is a top-level array carrying more messages than this endpoint accepts (`tenant_mcp.batch_too_large`); or the `Idempotency-Key` header is malformed (`tenant_api.idempotency_key_invalid`), disagrees with the body's `idempotency_key` (`tenant_api.idempotency_key_conflict`), or was sent to an action that cannot replay a retry (`tenant_api.idempotency_unsupported`). Nothing ran.
- `401`: No bearer credential, or one that did not resolve. Deliberately ONE undifferentiated answer for absent / unknown / revoked / expired, so the endpoint is never an oracle over the key space.
- `403`: The credential is good but the surface is not open to it — the platform or account API switch is off, or the holder lacks the `api.access` capability. The `code` says which.
- `404`: No such tool. The body names no tool and is identical for every unrecognised name.
- `429`: Over this key's per-minute cap. Carries `Retry-After` and `error.retry_after_seconds`.
