To display an array example with multiple items, add the example on the array level instead of item level: cities: type: array items: type: string example: - Pune - Mumbai - Bangaluru # or # example: [Pune, Mumbai, Bangaluru] In case I'm building a fuzzer for a REST API that has an OpenAPI (Swagger) definition. In my Swagger documentation, I have to use same pattern multiple time. To review, open the file in an editor that reveals hidden Unicode characters. com format: regex pattern: '\S' while generating a class it is generating as I wrote a parameter that "type:" is "string" and "example:" is a text datetime without time zone like "2021-09-01 00:00:00". "example": "<project><foo>1</foo><bar>2</bar></project>" Alternatively, you can define a schema for the response, and Swagger UI will generate examples based on the schema. The example date-time format will look like this: &quot;2021-06-20T01:02:0 I have a Date format coming from API like this: "start_time": "2015-10-1 3:00 PM GMT+1:00" Which is YYYY-DD-MM HH:MM am/pm GMT timestamp.
