ClientProperties Property

A collection of table fields that describe properties of the client.

Data Type


Default Value



This property holds a collection of table fields that represent client properties. During the connection process, these properties will be sent to the server.

Each line contains a AMQP table field. The table field structure should follow this pattern: "key, type(int), value".

Key must be an ASCII string that:

  • Starts with an ASCII letter, $, or $ character.
  • Only contains ASCII letters, digits, underscores, $, and $ characters.
  • Is unique among all sibling table field key names.
  • Is no longer than 128 characters.
Value is table field's value and must be formatted according to the type. Type is the table field's value type. Acceptable value types are:

Value Type JSON Value TypeDescriptionValue Format
fvtBoolean (0) boolean Boolean "True" or "False"
fvtByte (1) byte Byte -128 to 127
fvtUbyte (2) ubyte Unsigned byte 0 to 255
fvtShort (3) short Short -32768 to 32767
fvtUshort (4) ushort Unsigned short 0 to 65535
fvtInt (5) int Integer -2147483648 to 2147483647
fvtUint (6) uint Unsigned integer 0 to 4294967295
fvtLong (7) long Long -9223372036854775808 to 9223372036854775807
fvtUlong (8) ulong Unsigned long 0 to 18446744073709551615
fvtFloat (9) float Float IEEE 754 32-bit floating point number
fvtDouble (10) double Double IEEE 754 64-bit floating point number
fvtDecimal (11) decimal Decimal Hex-encoded byte string
fvtSstring (12) sstring Short string UTF-8 string data, limited to 255 bytes; may not contain null bytes (\0)
fvtString (13) string String String data
fvtArray (14) array Array JSON array of type-value pairs
fvtTimestamp (15) timestamp Timestamp Number of milliseconds since the Unix epoch (January 1, 1970 00:00:00 UTC)
fvtTable (16) table Table JSON object containing name-type-value tuples
fvtNull (17 - default)null Null N/A (Value is ignored)

For the fvtArray (14) value type, the Value should be specified as a JSON array of type-value pairs; for example:

  { "type": "int", "value": 23 },
  { "type": "int", "value": -52 },
  { "type": "int", "value": 153325 }

For the fvtTable (16) value type, theValue; should be specified as a JSON object containing name-type-value tuples; for example:

  { "name": "Test1", "type": "long", "value": 12345678901234 },
  { "name": "Test2", "type": "boolean", "value": "false" },
  { "name": "Test3", "type": "string", "value": "This is a test." }

Notes regarding fvtArray (14) and fvtTable (16) type Value:

  • All "type" fields in the JSON content must be set to one of the value types in the table above.
  • For fvtTable (16) type Value, all "name" fields must adhere to the rules described above by the Key documentation.
  • Nesting and mixing multiple levels of arrays and tables in the JSON is allowed.

While the task does not send any client properties by default, it is common for AMQP clients to send "product", "version", and "platform" properties to help identify themselves.
