Private Channels - DexBuilder Docs

Private channels use a Broker API Key and identify a user wallet in auth.wallet_address. Keep the API Secret local. See Broker WebSocket authentication. Use the channel prefix ec. A single item can be subscribed with items, or all private updates can be selected with all: true.

{
  "t": 1720000000123,
  "id": "private-1",
  "op": "subscribe",
  "ch": "ec.orders",
  "payload": {
    "items": [
      {
        "condition_id": "ge_condition-1"
      }
    ]
  },
  "auth": {
    "method": "broker_api_key",
    "key": "YOUR_BROKER_API_KEY",
    "sign": "HEX_SIGNATURE",
    "wallet_address": "<USER_WALLET>"
  }
}

Use the same payload shape with op: "unsubscribe". If the connection has been authenticated with server.sign, later subscriptions and unsubscriptions can omit auth.

`ec.orders`

Order state changes for the authenticated account.

{
  "type": "update",
  "ch": "ec.orders",
  "err": null,
  "result": {
    "order_id": "order-1",
    "client_order_id": "client-1",
    "event_id": "event-1",
    "condition_id": "ge_condition-1",
    "token_id": "ge_token-yes",
    "outcome": "Yes",
    "side": "BUY",
    "order_mode": "LIMIT",
    "order_type": "GTC",
    "px": "0.45",
    "qty": "10",
    "filled_qty": "4",
    "left_qty": "6",
    "status": "OPEN",
    "created_ts": 1720000000123,
    "updated_ts": 1720000001123
  }
}

WebSocket status is an uppercase upstream UI state, separate from the five lowercase REST order states. Examples include PROCESSING, OPEN, CANCELLING, MATCHED, CANCELED, and FAILED.

`ec.usertrades`

Trades belonging to the authenticated account.

{
  "type": "update",
  "ch": "ec.usertrades",
  "err": null,
  "result": {
    "trade_id": "trade-1",
    "order_id": "order-1",
    "client_order_id": "client-1",
    "condition_id": "ge_condition-1",
    "event_id": "event-1",
    "token_id": "ge_token-yes",
    "outcome": "Yes",
    "side": "BUY",
    "role": "MAKER",
    "px": "0.45",
    "qty": "4",
    "fee_rate": "0.001",
    "status": "CONFIRMED",
    "created_ts": 1720000000123
  }
}

Only confirmed account trades are delivered. Depending on configuration, matched events may also be delivered.

`ec.positions`

Position changes for the authenticated account.

{
  "type": "update",
  "ch": "ec.positions",
  "err": null,
  "result": {
    "position_id": "12345",
    "event_id": "event-1",
    "token_id": "ge_token-yes",
    "outcome": "Yes",
    "qty": "10",
    "avg_px": "0.45",
    "settle_status": "UNSETTLED",
    "locked_qty": "0",
    "available_qty": "10",
    "claimable_amount": "0",
    "updated_ts": 1720000001123
  }
}

For security and product-surface reasons, mark-price fields are not documented or exposed here.

`ec.settlements`

Settlement and claimability updates.

{
  "type": "update",
  "ch": "ec.settlements",
  "err": null,
  "result": {
    "position_id": "12345",
    "condition_id": "ge_condition-1",
    "event_id": "event-1",
    "winning_outcome": "Yes",
    "is_winner": true,
    "claimable_amount": "10.00",
    "created_ts": 1720000002123
  }
}

Private subscriptions are event-driven. Query the corresponding REST endpoint after reconnecting to recover the current state; a private subscription does not imply a full initial account snapshot.
