# List campaigns

> GET /campaigns — list your campaigns, newest first.

`GET /campaigns`

Returns your campaigns ordered by creation time (newest first), wrapped in a list object. The `limit` parameter is optional — if you omit it, all campaigns are returned in a single response.

**Query parameters**

| --- | --- | --- | --- |
| `limit` | number | No | Number of campaigns to retrieve. Minimum `1`, maximum `100`. |
| `after` | string | No | The ID after which to retrieve more campaigns (pagination). The ID itself is excluded. Cannot be combined with `before`. |
| `before` | string | No | The ID before which to retrieve more campaigns (pagination). The ID itself is excluded. Cannot be combined with `after`. |
