post_v1_campaign
CreateCampaign creates a campaign as a DRAFT and returns it. A draft is inert: nothing is sent, no connector is touched and no budget is committed until the campaign is launched.
CreateCampaign creates a campaign as a DRAFT and returns it.
A draft is inert: nothing is sent, no connector is touched and no budget is committed until the campaign is launched. The channels named here are validated and de-duplicated by kind (one executor per kind), and every channel starts "pending" whatever the caller claims — a client can never assert a launched state.
| Tool | post_v1_campaign |
| Door | https://api.hanzo.ai/v1/mcp |
| Method | tools/call (JSON-RPC 2.0) |
| Arguments | 6 |
| Operation | POST /v1/campaign |
| Product | campaign |
Arguments
| Field | Type | Required | Default | Values | Description |
|---|---|---|---|---|---|
audience | string | — | — | — | Audience is the segment or audience selector this campaign targets. |
budget | integer | — | — | — | Budget is the campaign's total budget in CENTS. Negative reads as 0. |
channels | ChannelSpec[] | — | — | — | Channels are the fan-out targets, at most one per kind (paid, organic, email) and at most 12. A channel's status and provider id are server-owned: whatever the caller sends for them is replaced with "pending". |
content | string[] | — | — | — | Content is the ordered creative set. Content[0] is the active creative and the rest are A/B variants; at most 32, empty entries dropped. |
name | string | — | — | — | Name is the campaign's display name. Required; trimmed and capped at 2048 characters. |
scheduleAt | integer | — | — | — | ScheduleAt is when the campaign should run, in unix seconds. Negative reads as 0 (immediately). |
tools/list declares a type and a description for each field and nothing further. A — means neither the door nor that operation constrains the field.
Object types
ChannelSpec is an object this tool's fields are made of, declared inside the tool's own schema and enumerated in full below.
ChannelSpec
| Field | Type | Required | Default | Values | Description |
|---|---|---|---|---|---|
account | string | — | — | — | provider account ref (ad-account/page/list id) |
detail | string | — | — | — | honest last-outcome detail (never a secret) |
externalId | string | — | — | — | — |
kind | string | — | — | — | paid | organic | email |
platform | string | — | — | — | meta | google | x | instagram | (email provider) |
status | string | — | — | — | pending | live | paused | failed | unavailable |
Call it
A tools/call carries every argument in one flat object — nothing binds to a path or a query string. Nothing above is required, so every declared argument is shown rather than a guess at which matter.
curl -X POST https://api.hanzo.ai/v1/mcp \
-H "Authorization: Bearer $HANZO_API_KEY" \
-H "Content-Type: application/json" \

}'Values are the operation's own defaults and enumerated values where it declares them, and a <placeholder> where neither source declares one. budget and scheduleAt hold stand-ins that cannot be spelled that way — JSON gives a number, a boolean and a timestamp no placeholder form — so those values are this page's, not the API's. Neither the door nor the operation declares one. tools/list needs no credential; tools/call does — called without one the door answers HTTP 200 with a JSON-RPC result whose isError is set and whose text says what was missing.

How is this guide?
get_v1_campaign_summary
SummarizeCampaigns returns the org's go-to-market roll-up: how many campaigns exist, how many are live, their total budget in cents, and which channel executors this deployment can actually reach.
post_v1_campaign_id_channels
AddCampaignChannel adds a channel to a campaign, or REPLACES the one it already has of that kind, and returns the updated campaign.
