# Fieldwork settings

> Set the automatic closing of data collection and the advertising pixel IDs.

Fieldwork settings bring together the automatic closing of data collection and the advertising pixel IDs.

## Auto-close fieldwork

Fieldwork closes on its own as soon as one condition is met:

* the targeted **number of interviews**;
* or the **end date** you set.

<Note>
  If [weighting](/en/collecte/redressement) objectives are set, weighting is launched automatically at closing. Allow a few minutes between the last interview and data being ready. A **confirmation e-mail** notifies you once fieldwork is closed and weighting is complete; it flags the final report, which includes the weights.
</Note>

## Advertising pixels

An advertising pixel is an ID provided by a social network. By entering it here, you **place that pixel on the respondent questionnaire**: the network can then attribute the respondents coming from it to your campaigns. Enter one ID per network used as a sample source.

| Field | What to enter |
| - | - |
| **Meta pixel ID** | The ID of your Meta pixel (Facebook, Instagram). |
| **Pinterest pixel ID** | The ID of your Pinterest pixel. |
| **Snapchat pixel ID** | The ID of your Snapchat pixel. |
| **TikTok pixel ID** | The ID of your TikTok pixel. |
| **Reddit pixel ID** | The ID of your Reddit pixel. |

<Note>
  Entering the ID in poll\&roll is not enough. Each network also requires **configuration on your side, on its own platform** (that network's ads manager). The poll\&roll field places the pixel on the questionnaire; setting up the campaign and its tracking remains to be done on the network.
