# Enable an acquirer connection

`POST /merchants/{username}/acquirers/{conn_id}/enable`

## Request

- Base URL: `https://gateway.pmnts.io/v2/partners`
- URL: `https://gateway.pmnts.io/v2/partners/merchants/{username}/acquirers/{conn_id}/enable`
- Auth: HTTP basic

Flips `enabled` to `true` across the underlying links. The routing
toggle only — config and MID/TID are untouched. No body is expected.

## Response `200`

The enabled connection.

- AcquirerConnection: The combined state across every acquirer link provisioned for one acquirer. Boarding is synchronous, so a connection that exists is always boarded.
  - `acquirer_name` string, nullable, required: The acquirer's display name (e.g. `NAB`).
  - `merchant_id` string, nullable: The acquirer-assigned MID (e.g. `ent_a1b2c3d4`).
  - `terminal_id` string, nullable: The acquirer-assigned TID (e.g. `T0001`), or a Fat Zebra-generated 8-character placeholder (e.g. `ACMEC001`) if none was supplied at board time. Immutable once set.
  - `currencies` string[]: Currencies the connection can transact.
  - `schemes` string[]: Networks the merchant can transact for this acquirer.
  - `modes` string[]: Transaction modes the connection supports.
  - `wallets` string[]: Wallets the connection accepts.
  - `three_ds_enabled` boolean: Whether a boarded processor for this acquirer supports 3DS.
  - `status` 'enabled' | 'disabled', required: Routing toggle across the underlying links — disable to turn the connection off without deleting it.

## Other responses

- `401`: Missing or invalid HTTP Basic credentials.
- `404`: Resource not found.
