What is a unique operation in Swagger?
Swagger defines a unique operation as a combination of a path and an HTTP method. This means that two GET or two POST methods for the same path are not allowed – even if they have different parameters (parameters have no effect on uniqueness). Minimal example of an operation:
What is required ID in Swagger?
Required. A unique id for the operation that can be used by tools reading the output for further and easier manipulation. For example, Swagger-Codegen will use the nickname as the method name of the operation in the client it generates. The value MUST be alphanumeric and may include underscores.
What are the API parameters in Swagger?
The API client needs to provide appropriate parameter values when making an API call, such as /users/5 or /users/12. For each path, you define operations (HTTP methods) that can be used to access that path. Swagger 2.0 supports get, post, put, patch, delete, head, and options.
What is Swagger Codegen?
Swagger Codegen: It allows us to generate the API client libraries, server stubs, and documentation automatically. Swagger core: It consists of java related libraries which are used for creating, consuming and working with API definitions.

What is Swagger operation?
In Swagger terms, paths are endpoints (resources) that your API exposes, such as /users or /reports/summary , and operations are the HTTP methods used to manipulate these paths, such as GET, POST or DELETE.

Paths
API paths and operations are defined in the global paths section of the API specification.
Path Templating
Swagger supports path templating, meaning you can use curly braces {} to mark parts of a URL as path parameters:
Operations
For each path, you define operations (HTTP methods) that can be used to access that path. Swagger 2.0 supports get, post, put, patch, delete, head, and options. A single path can support multiple operations, for example, GET /users to get a list of users and POST /users to add a new user.
Operation Parameters
Swagger supports operation parameters passed via path, query string, headers and request body. For details, see Describing Parameters.
operationId
Each operation may specify a unique operationId. Some code generators use this value to name the corresponding methods in code.
Query String in Paths
Query string parameters must not be included in paths. They should be defined as query parameters instead. Incorrect:
Marking as Deprecated
You can mark specific operations as deprecated to indicate that they should be transitioned out of usage:
Introduction
The OpenAPI Specification (OAS) defines a standard, language-agnostic interface to RESTful APIs which allows both humans and computers to discover and understand the capabilities of the service without access to source code, documentation, or through network traffic inspection.
Definitions
A document (or set of documents) that defines or describes an API. An OpenAPI definition uses and conforms to the OpenAPI Specification.
Specification
The OpenAPI Specification is versioned using Semantic Versioning 2.0.0 (semver) and follows the semver specification.
What is API declaration?
The API Declaration provides information about an API exposed on a resource. There should be one file per Resource described. The file MUST be served in the URL described by the path field.
What is response message object?
The Response Message Object describes a single possible response message that can be returned from the operation call, and maps to the responseMessages field in the Operation Object. Each Response Message allows you to give further details as to why the HTTP status code may be received.
What is API?
API stands for Application Programming Interface. It defines how two pieces of software talk to each other. There are several types of APIs, but the swagger specifically deals with the Web API.
Request Body
We mainly specify the request body in JSON format for some methods such as PUT, POST, etc. The body is treated as parameters like path in url. Unlike these parameters, we create the schema for the request body that specifies how the JSON body would look like.
Security
Here, Security means authentication and authorization. Authentication means to validate the user through their username and password. The authorization means allowing the user to access the data.
Documentation
The OAS file or API file contains the human-readable description of elements that generates the documentation automatically. In other words, we can say that a description section is added for the API, for each operation which is a combination of path and method, for each parameter, and for each response element.
YAML
YAML stands for Ain't Markup Language. It is not a Markup language like HTML. It is used for the data, not for the content. YAML uses minimum characters as compared to JSON and XML. It is mainly used for the configuration
List
List in YAML is similar to the JSON. We need to use a dash to indicate a list item.
Multi-line Strings
As we know that strings do not contain quotation marks so we need special characters for multiline strings. The following are the characters used for the multi-line strings:
Parameter Types
OpenAPI 3.0 distinguishes between the following parameter types based on the parameter location. The location is determined by the parameter’s in key, for example, in: query or in: path .
Path Parameters
Path parameters are variable parts of a URL path. They are typically used to point to a specific resource within a collection, such as a user identified by ID. A URL can have several path parameters, each denoted with curly braces { } .
Query Parameters
Query parameters are the most common type of parameters. They appear at the end of the request URL after a question mark (? ), with different name=value pairs separated by ampersands ( & ). Query parameters can be required and optional.
Header Parameters
An API call may require that custom headers be sent with an HTTP request. OpenAPI lets you define custom request headers as in: header parameters. For example, suppose, a call to GET /ping requires the X-Request-ID header:
Cookie Parameters
Operations can also pass parameters in the Cookie header, as Cookie: name=value. Multiple cookie parameters are sent in the same header, separated by a semicolon and space.
Required and Optional Parameters
By default, OpenAPI treats all request parameters as optional. You can add required: true to mark a parameter as required. Note that path parameters must have required: true, because they are always required.
schema vs content
To describe the parameter contents, you can use either the schema or content keyword. They are mutually exclusive and used in different scenarios. In most cases, you would use schema. It lets you describe primitive values, as well as simple arrays and objects serialized into a string.

Paths
Path Templating
- You can use curly braces {} to mark parts of an URL as path parameters: The API client needs to provide appropriate parameter values when making an API call, such as /users/5 or /users/12.
Operations
- For each path, you define operations (HTTP methods) that can be used to access that path. OpenAPI 3.0 supports get, post, put, patch, delete, head, options, and trace. A single path can support multiple operations, for example GET /users to get a list of users and POST /usersto add a new user. OpenAPI defines a unique operation as a combination of a path and an HTTP method…
Operation Parameters
- OpenAPI 3.0 supports operation parameters passed via path, query string, headers, and cookies. You can also define the request body for operations that transmit data to the server, such as POST, PUT and PATCH. For details, see Describing Parameters and Describing Request Body.
Query String in Paths
- Query string parameters must not be included in paths. They should be defined as query parametersinstead. Incorrect: Correct: This also means that it is impossible to have multiple paths that differ only in query string, such as: This is because OpenAPI considers a unique operation as a combination of a path and the HTTP method, and additional parameters do not make the oper…
Deprecated Operations
- You can mark specific operations as deprecatedto indicate that they should be transitioned out of usage: Tools may handle deprecated operations in a specific way. For example, Swagger UI displays them with a different style:
Overriding Global Servers
- The global serversarray can be overridden on the path level or operation level. This is useful if some endpoints use a different server or base path than the rest of the API. Common examples are: 1. Different base URL for file upload and download operations. 2. Deprecated but still functional endpoints. Did not find what you were looking for?
