Swagger parameters are a way to define the structure and behavior of a parameter in a Swagger document. They are used to describe the required, minimum, and maximum values for a parameter, as well as the type of the parameter (e.g. string, number, boolean). For example, you might define a parameter in your Swagger document with the following syntax: yaml param: name: name in: path required: true type: string

In this example, the name parameter is defined with a name attribute, a in attribute of path, a required attribute of true, and a type attribute of string. This means that the parameter must be present in the path of the API document, and must be of type string. You can also define complex parameters with multiple properties using attributes, as shown in the following example: yaml param: name: name in: path required: true type: string description: "A description of the parameter" enum: - value1 - value2

In this example, the name parameter has multiple properties, including a description attribute, an enum attribute, and a type attribute. The enum attribute specifies the possible values for the parameter, and the description attribute provides a brief description of the parameter.
