Documentation Scope

Welcome to the official documentation for the Favorite Service’s REST API. This document is designed to provide a comprehensive guide to interfacing with our Favorite Service exclusively through RESTful API endpoints.

Intended Audience

This documentation is intended for developers and integrators who are looking to interact with the Favorite Service via HTTP requests for purposes such as creating, updating, deleting and querying Favorite objects.

Overview

Within these pages, you will find detailed information on how to effectively utilize the REST API, including authentication methods, request and response formats, endpoint descriptions, and examples of common use cases.

Beyond REST It’s important to note that the Favorite Service also supports alternative methods of interaction, such as gRPC and messaging via a Message Broker. These communication methods are beyond the scope of this document. For information regarding these protocols, please refer to their respective documentation.

Authentication And Authorization

To ensure secure access to the Favorite service’s protected endpoints, a project-wide access token is required. This token serves as the primary method for authenticating requests to our service. However, it’s important to note that access control varies across different routes:

Protected API: Certain API (routes) require specific authorization levels. Access to these routes is contingent upon the possession of a valid access token that meets the route-specific authorization criteria. Unauthorized requests to these routes will be rejected.

**Public API **: The service also includes public API (routes) that are accessible without authentication. These public endpoints are designed for open access and do not require an access token.

Token Locations

When including your access token in a request, ensure it is placed in one of the following specified locations. The service will sequentially search these locations for the token, utilizing the first one it encounters.

Location Token Name / Param Name
Query access_token
Authorization Header Bearer
Header clonesahibinden-access-token
Cookie clonesahibinden-access-token

Please ensure the token is correctly placed in one of these locations, using the appropriate label as indicated. The service prioritizes these locations in the order listed, processing the first token it successfully identifies.

Api Definitions

This section outlines the API endpoints available within the Favorite service. Each endpoint can receive parameters through various methods, meticulously described in the following definitions. It’s important to understand the flexibility in how parameters can be included in requests to effectively interact with the Favorite service.

This service is configured to listen for HTTP requests on port 3006, serving both the main API interface and default administrative endpoints.

The following routes are available by default:

This service is accessible via the following environment-specific URLs:

Parameter Inclusion Methods: Parameters can be incorporated into API requests in several ways, each with its designated location. Understanding these methods is crucial for correctly constructing your requests:

Query Parameters: Included directly in the URL’s query string.

Path Parameters: Embedded within the URL’s path.

Body Parameters: Sent within the JSON body of the request.

Session Parameters: Automatically read from the session object. This method is used for parameters that are intrinsic to the user’s session, such as userId. When using an API that involves session parameters, you can omit these from your request. The service will automatically bind them to the API layer, provided that a session is associated with your request.

Note on Session Parameters: Session parameters represent a unique method of parameter inclusion, relying on the context of the user’s session. A common example of a session parameter is userId, which the service automatically associates with your request when a session exists. This feature ensures seamless integration of user-specific data without manual input for each request.

By adhering to the specified parameter inclusion methods, you can effectively utilize the Favorite service’s API endpoints. For detailed information on each endpoint, including required parameters and their accepted locations, refer to the individual API definitions below.

Common Parameters

The Favorite service’s business API support several common parameters designed to modify and enhance the behavior of API requests. These parameters are not individually listed in the API route definitions to avoid repetition. Instead, refer to this section to understand how to leverage these common behaviors across different routes. Note that all common parameters should be included in the query part of the URL.

Supported Common Parameters:

By utilizing these common parameters, you can tailor the behavior of API requests to suit your specific requirements, ensuring optimal performance and usability of the Favorite service.

Error Response

If a request encounters an issue, whether due to a logical fault or a technical problem, the service responds with a standardized JSON error structure. The HTTP status code within this response indicates the nature of the error, utilizing commonly recognized codes for clarity:

Each error response is structured to provide meaningful insight into the problem, assisting in diagnosing and resolving issues efficiently. 

{
  "result": "ERR",
  "status": 400,
  "message": "errMsg_organizationIdisNotAValidID",
  "errCode": 400,
  "date": "2024-03-19T12:13:54.124Z",
  "detail": "String"
}

Object Structure of a Successfull Response

When the Favorite service processes requests successfully, it wraps the requested resource(s) within a JSON envelope. This envelope not only contains the data but also includes essential metadata, such as configuration details and pagination information, to enrich the response and provide context to the client.

Key Characteristics of the Response Envelope:

Design Considerations: The structure of a API’s response data is meticulously crafted during the service’s architectural planning. This design ensures that responses adequately reflect the intended data relationships and service logic, providing clients with rich and meaningful information.

Brief Data: Certain API’s return a condensed version of the object data, intentionally selecting only specific fields deemed useful for that request. In such instances, the API documentation will detail the properties included in the response, guiding developers on what to expect.

API Response Structure

The API utilizes a standardized JSON envelope to encapsulate responses. This envelope is designed to consistently deliver both the requested data and essential metadata, ensuring that clients can efficiently interpret and utilize the response.

HTTP Status Codes:

Success Response Format:

For successful operations, the response includes a "status": "OK" property, signaling the successful execution of the request. The structure of a successful response is outlined below: 

{
  "status":"OK",
  "statusCode": 200,   
  "elapsedMs":126,
  "ssoTime":120,
  "source": "db",
  "cacheKey": "hexCode",
  "userId": "ID",
  "sessionId": "ID",
  "requestId": "ID",
  "dataName":"products",
  "method":"GET",
  "action":"list",
  "appVersion":"Version",
  "rowCount":3
  "products":[{},{},{}],
  "paging": {
    "pageNumber":1, 
    "pageRowCount":25, 
    "totalRowCount":3,
    "pageCount":1
  },
  "filters": [],
  "uiPermissions": []
}

Handling Errors:

For details on handling error scenarios and understanding the structure of error responses, please refer to the “Error Response” section provided earlier in this documentation. It outlines how error conditions are communicated, including the use of HTTP status codes and standardized JSON structures for error messages.

Resources
