# A campaign's headline metrics since \`since\`

`GET /business/campaigns/{campaignId}/stats`

## Request

- Base URL: `https://api.tryfuse.ai/api/v1`
- URL: `https://api.tryfuse.ai/api/v1/business/campaigns/{campaignId}/stats`
- Auth: HTTP basic

Returns the campaign's headline email metrics. The `total*` counters accumulate from `since` (default: 12 months ago). `totalOpened` and `totalClicked` count distinct contacts, not events; `totalOpened` covers only emails sent while the campaign's open tracking was on, so it is 0 when tracking is off. Only the token owner's own campaigns resolve: a campaign delegated to you, one shared by your team's visibility settings, and a deleted one all answer 404. Rate limit: 30 requests/minute and 1,000/day per token owner, shared by every campaign, scheduled-send, campaign-template and knowledge-hub endpoint.

Errors:
- `404` `CAMPAIGN_NOT_FOUND` — No campaign with this id exists, it belongs to another account (including a campaign delegated to you or shared by your team's visibility settings), or it has been deleted.
- `422` `VALIDATION_FAILED` — `since` is not an ISO 8601 date-time, or campaignId is not a 24-character hex id.
- `429` `RATE_LIMITED` — More than 30 campaign requests in a minute, or 1,000 in a day, for this token owner (the bucket is shared by every /business/campaigns, /business/scheduled-sends, /business/campaign-templates and /business/knowledge-hubs call).
- `500` `UNEXPECTED_ERROR` — An unhandled failure; the detail stays in our logs and is never returned.

Requires one of the following token scopes: campaigns.

## Path parameters

- `campaignId` string, required: The campaign's id (24-character hex ObjectId), as returned by POST /business/campaigns or as the campaignId of a GET /business/campaigns row.

## Query parameters
