Process REST API programming

Each REST API has a schema for the request content. Each parameter is of type string, boolean, or integer. The framework tries to parse the client input to the type that is specified in the schema. For a string parameter, values are passed as strings, whether they are a character string, a Boolean, or a number. For example, the word value is parsed as the "value" string, the number 42 is parsed as the "42" string, and the Boolean value true is parsed as the "true" string. Moreover, for Boolean and number types, string values that can be parsed as Boolean or numbers respectively are also accepted. But if a string value is passed and cannot be parsed to a Boolean or number, a 400 error is returned. For example, "T" is not a valid value for a Boolean parameter.
