Unique Transmission ID

When you submit a transmission containing one or more submissions, the system generates a Unique Transmission ID (UTID). The UTID is a unique number to identify the transmission.

The format of the UTID includes various fields separated by colons (:) as follows:

  • UUID: a universally unique identifier (UUID) is an identifier standard defined by the Internet Engineering Task Force (IETF) in Request For Comments (RFC) 4122. The UUID consists of a 16-octet (128-bit) number. This is a mandatory field. The UUID is represented by 32 hexadecimal digits, displayed in five groups separated by hyphens.

    For example: 550e8400-e29b-41d4-a716-446655440000

  • Application ID: the Application ID will be SYS12 and is a mandatory field.

  • Transmitter Control Code: is an alphanumeric field that contains the Transmitter's TCC and is mandatory.

  • Reserved: is an empty field (no space between colons).

  • Request Type: the Request Type defines the types of request which must be “T" (Transactional) and is mandatory.

For example, the UTID for a transmission is as follows:550e8400-e29b-41d4-a716-446655440000:SYS12:BB002::T
