  • If you are using a legacy I/O Docs Node.js file, add property name in the parameter definition object.
  • If you are using I/O Docs Mashery version, add property title in the parameter definition object.
  • Make sure that the name value is not null or empty.
  • The name of the parameter must match exactly with the name of the parameter expected by the API. Names may be compared in a case-sensitive manner.
