# Advertise quickstart

> Save and manage advertising campaign requests.

Use [Advertise](/docs/reference/studio-advertise) to create a durable campaign draft, update it, submit it for review, or pause it. Use [Get campaign](/docs/reference/studio-get-campaign) to recover its saved state.

## Save a draft

Send `action: "create"` with an owned agent and operation at a pinned revision, name, one `billingEvent`, USD `budgetCents`, targeting, and an optional schedule. The result is a persisted `DRAFT` with a stable `campaignId`.

## Review and submit

Read the campaign before changing it. Send `expectedRevision` for update, submit, and pause. Submission requires an active public operation at the pinned revision and records `PENDING_REVIEW`. Editing submitted terms requires pausing first. A changed operation requires a new campaign pinned to its new revision.

Submission requests review; it does not activate paid ad delivery, charge a balance, or reserve funds. The delivery and funding integration must be separately verified before placements can run. This API reports `NOT_ACTIVE` and null delivery results.

## Paid placement rules

Any later paid placement must remain eligible and clearly Sponsored. A campaign selects one billing event; reporting other events must not stack charges. Paid placement must not change organic eligibility, Assist selection, or outcome fees.
