The client will initiate the FIX Session by sending a Logon Message to the T4 FIX API server. Successful authentication will be responded with a Logon message echo. The Password field (Password - Tag 554) of the API server logon message will be identified with an asterisk. Drop of a physical connection will result in the end of a FIX Session. Upon reconnection, the client is required to start a new FIX Session with sequence number 1. The T4 API server will appropriately respond with messages starting with sequence number 1. ==== Authentication Requirements ==== After a successful physical connection to the T4 FIX API server, authenticated access is achieved with the following T4 input parameters in the client's Logon message: ^ Tag Name ^ Tag Number ^ Description ^ | TargetCompId | 56 | T4 Firm assigned in registration email or by firm | | UserName | 553 | T4 User | | Password | 554 | T4 Password | | | | | | SenderCompId | 49 | T4 Application Name. If using the simulator, enter ''T4Example'' for app name | | SecureData | 91 | License Code for the T4 Application. If you are using the T4Example use ''112A04B0-5AAF-42F4-994E-FA7CB959C60B'' | | SecureDataLen | 90 | Length of License Code string | Failure to provide the correct parameters in the Logon message will result in a logon failure. Appropriately, a [[Logout|Logout]] message will be sent to the client. The [[Logout|Logout]] message will contain a short description of the failure to help determine the cause of failed authentication. Thereafter, a physical disconnection will occur. As the FIX Session failed, the T4 FIX API will expect a new attempt for a new FIX session. The next Logon message (from the client) must start with sequence number 1. ==== Setting FIX Session Properties upon Logon ==== The T4 FIX API provides enhanced control of FIX Session functionalities. Upon successful authentication, the optional RefMsgType group allows the user to set FIX Session properties. The T4 FIX API processes such RefMsgTypes and applies the requested connection characteristics. The functionalities include the ability to control the messages transmitted during order entry (i.e. pending reports), the market data and order pricing format (i.e. decimal or ticks), disabling auto subscription to all user accounts, and listing of the current portfolio orders, fills, positions, and account details. ==== Default Logon Properties ==== A successful FIX Session is acknowledged with the expected (echo) Logon message. In addition, if no RefMsgTypes (Tag 372) are specified in the Logon request, the T4 FIX API will automatically return the account portfolio (as [[Execution Report|Execution Reports]]) and account details (as [[Collateral Report|Collateral Reports]]). To disable automatic portfolio/account-details listing (a.k.a. AutoPortfolio Refresh), the Logon request message must explicitly include a RefMsgType equal to "d" (Tag 372=d). This option (Tag 372=d) provides minimum login message flow at the expense of potentially missing order/fill updates that occurred while disconnected. By default, the T4 FIX API will also automatically subscribe to __all__ accounts authorized for the logon user (unless disabled with RefMsgType equal to "BB" - Tag 372=BB). ==== User Configuration ==== For a successful Login, the T4 FIX API requires the Logon User to have previously assigned accounts and exchanges. Before FIX API usage, the user is required to complete Market Data Requirements through its Firm set up page. Lack of proper configuration will result in a FIX Logout - indicating the lack of account or exchange assignment for the violating User. This requirement is not applied for Chart data logins (Tag 372=V). ==== Message Dictionary ==== ^ Tag ^ Field Name ^ Req'd ^ Comments ^ | | [[Standard Header]] | Y | MsgType = A | | 91 | SecureData | Y | License Code for the T4 Application | | 90 | SecureDataLen | Y | Length of License Code string | | 49 | SenderCompID | Y | T4 Application Name (inbound login into FIX API server).

The client disables portfolio lists (Tag 372=d). Subsequently, the login request is successful as signaled by a Login message response from the T4 FIX API. <color #22b14c>Login Request from T4 FIX API Client</color> <code> >> 6/7/2013 9:47:22 AM [FIXLOGIN] 34=1|49=T4Example|56=T4|52=20130607-14:47:22.872|91=112A04B0-5AAF-42F4-994E-FA7CB959C60B|90=36|98=0|108=30|553=_username_|554=_password_|384=1|372=d| [FIXLOGIN] [MsgSeqNum] 34 = 1 [SenderCompID] 49 = T4Example [TargetCompID] 56 = T4 Firm assigned in registration email or by firm [SendingTime] 52 = 20130607-14:47:22.872 [SecureData] 91 = 112A04B0-5AAF-42F4-994E-FA7CB959C60B [SecureDataLen] 90 = 36 [EncryptMethod] 98 = 0 [HeartBtInt] 108 = 30 [UserName] 553 = _username_ [Password] 554 = _password_ [NoMsgTypes] 384 = 2 [RefMsgType] 372 = d (DISABLE_PORTFOLIO_LISTING) [RefMsgType] 372 = D (DECIMAL PRICING) </code> <color #22b14c>Successful Login Response from T4 FIX API</color> <code> << 6/7/2013 9:47:24 AM [fixlogin] 34=1|49=T4|56=T4Example|50=T4FIX|52=20130607-14:47:24.085|98=0|108=30|553=_username_|554=***|1408=4.1.1.1| [FIXLOGIN] [MsgSeqNum] 34 = 1 [SenderCompID] 49 = T4 [TargetCompID] 56 = T4Example [SenderSubID] 50 = T4FIX [SendingTime] 52 = 20130607-14:47:24.085 [EncryptMethod] 98 = 0 [HeartBtInt] 108 = 30 [UserName] 553 = _username_ [Password] 554 = *** [DefaultCstmApplVerID] 1408 = 4.1.1.1 </code> developers/logon.txt Last modified: 2025/08/12 12:37by rob
