  • data is required and must contain at least one object. Requests that omit data, or send "data": [], are rejected with "missing Ping data".
  • Any objects included in data are echoed back unchanged in the Pong response.
  • seqNum may be omitted from successful Pong responses.
  • Error responses use seq (not seqNum) and include an error object with code and msg fields.
