# Upload New Place List

`POST /place_lists/upload`

## Request

- Base URL: `https://api.mediamath.com/api/v3.0`
- URL: `https://api.mediamath.com/api/v3.0/place_lists/upload`
- Auth: OAuth 2
  - Authorization code: `https://auth.mediamath.com/authorize`
  - Token URL: `https://auth.mediamath.com/oauth/token` scopes: `offline_access`, `manage:services`
- TypeScript: <https://skmtc.dev/mediamath/apis/campaigns-api/docs/place_lists/upload/post.ts> (a function with typed inputs; its response is checked against the schema)

Create a place list from a CSV file.

The CSV upload is atomic: if any row is invalid, the API returns `400`
with validation errors and no place list or places are created. The CSV
header must be exactly `name,latitude,longitude,radius_meters,external_id`.
`sensitive_location_attestation` is required and must be `"true"`.

Before uploading Place List locations through the API, API users must
accept the sensitive-location attestation. Accepting this field confirms
the following attestation on behalf of the API user for this request:

```text
I represent and warrant that these locations are not being used to
target or identify individuals at sensitive locations, and that I have
the rights and consents necessary for this targeting, including consent
to share with third parties where required.
```

For guidance on what qualifies as a sensitive location, see
[Places attestation guidelines](https://support.infillion.com/s/article/Places).

Requests submitted without `sensitive_location_attestation`, or with it
set to any value other than `"true"`, are rejected with a `400`
`invalid-request` error on `/sensitive_location_attestation`. This is a
per-request acknowledgment, not a one-time account-level setting.

The attestation language may be updated over time.
