API design principles

If your parameter schema and example conflict, there is a problem in the definition of the schema or the example. Solve it before you ship it.

Examples

Given the following configuration:

rules:
  no-invalid-parameter-examples:
    severity: error
    allowAdditionalProperties: false

Example of incorrect parameter example:

paths:
  /results:
    get:
      summary: Search Chess Results
      operationId: searchChessResult
      parameters:
        - name: username
          in: query
          schema:
            type: string
            maxLength: 15
          description: Value to query the chess results against usernames
          example: ThisUsernameIsTooLong

Example of correct parameter example:

paths:
  /results:
    get:
      summary: Search Chess Results
      operationId: searchChessResult
      parameters:
        - name: username
          in: query
          schema:
            type: string
            maxLength: 10
          description: Value to query the chess results against usernames
          example: ella
