# Resume a paused campaign

`POST /api/v1/campaigns/{id}/resume`

## Request

- Base URL: `https://api.sendly.now`
- URL: `https://api.sendly.now/api/v1/campaigns/{id}/resume`
- Auth: one of:
  - HTTP bearer
  - API key in cookie `better-auth.session_token`
  - OAuth 2 (authorization code, authorization URL `https://app.sendly.now/api/auth/oauth2/authorize`, token URL `https://app.sendly.now/api/auth/oauth2/token`, scopes: `campaigns:write`)

Resume a `PAUSED` campaign from the last entry in its per-contact send ledger. That ledger also dedupes, so a contact already sent to is skipped rather than mailed twice. Takes no request body.

Requires the `campaigns:write` scope — Create, edit, and organize your campaigns.

## Path parameters

- `id` string, uuid, required: Resource id.

## Response `200`
