# Connections

> Choose which sellers receive your briefs, activate them per advertiser, and test safely in sandbox.

**Connections** decide which sellers your briefs reach. "Show me where I can advertise" opens the
**Sellers** page, with three tabs: your advertiser's sellers, media partners, and available sellers.
Search and filter by market and channel.

## Seller status

Each seller card ends with a status:

| Status                                      | Meaning                                                                     |
| ------------------------------------------- | --------------------------------------------------------------------------- |
| **Active** · Buying for N advertisers       | Selected and ready for N of your advertisers.                               |
| **Provisioning** · Setting up N advertisers | The seller is creating accounts for you. Usually takes seconds to a minute. |
| **Active · Ready**                          | Eligible, but no advertiser uses it yet.                                    |
| **Add seller**                              | Available, not selected.                                                    |

An **Action required** chip counts sellers waiting on you, for example an account mapping.

## Selection and activation

Two settings combine:

* **Account-wide selection**: `DEFAULT` (included when eligible), `ALWAYS_INCLUDE` or
  `ALWAYS_EXCLUDE`.
* **Per-advertiser activation**: `ENABLED`, `DEFAULT` or `DISABLED` for one advertiser.

Change them in the page or with `save_connection`, one intent per call. Connecting, selecting and
mapping sellers never costs IUs.

## Missing a seller?

If a publisher you want is not on Semicola yet, ask for it: "Request supply from a publisher" files a
supply ask with the domain and channel. The team follows up with the seller.

## Sandbox

Sandbox advertisers run the full loop (discovery, proposals, launch, delivery) against sellers without
real spend. Delivery is simulated, so you can watch pacing move. Use a sandbox advertiser to rehearse an
integration before running live.
