Documentation Scope

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

Intended Audience

This documentation is intended for developers and integrators who are looking to interact with the Content Service via HTTP requests for purposes such as creating, updating, deleting and querying Content 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 Content 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 Content 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	linkedin-access-token
Cookie	linkedin-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 Content 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 Content service.

This service is configured to listen for HTTP requests on port 3001, serving both the main API interface and default administrative endpoints.

The following routes are available by default:

API Test Interface (API Face): /
Swagger Documentation: /swagger
Postman Collection Download: /getPostmanCollection
Health Checks: /health and /admin/health
Current Session Info: /currentuser
Favicon: /favicon.ico

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

Preview: https://linkedin.prw.mindbricks.com/content-api
Staging: https://linkedin-stage.mindbricks.co/content-api
Production: https://linkedin.mindbricks.co/content-api

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 Content 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 Content 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:

getJoins (BOOLEAN): Controls whether to retrieve associated objects along with the main object. By default, getJoins is assumed to be true. Set it to false if you prefer to receive only the main fields of an object, excluding its associations.
excludeCQRS (BOOLEAN): Applicable only when getJoins is true. By default, excludeCQRS is set to false. Enabling this parameter (true) omits non-local associations, which are typically more resource-intensive as they require querying external services like ElasticSearch for additional information. Use this to optimize response times and resource usage.
requestId (String): Identifies a request to enable tracking through the service’s log chain. A random hex string of 32 characters is assigned by default. If you wish to use a custom requestId, simply include it in your query parameters.
caching (BOOLEAN): Determines the use of caching for query API. By default, caching is enabled (true). To ensure the freshest data directly from the database, set this parameter to false, bypassing the cache.
cacheTTL (Integer): Specifies the Time-To-Live (TTL) for query caching, in seconds. This is particularly useful for adjusting the default caching duration (5 minutes) for get list queries. Setting a custom cacheTTL allows you to fine-tune the cache lifespan to meet your needs.
pageNumber (Integer): For paginated get list API’s, this parameter selects which page of results to retrieve. The default is 1, indicating the first page. To disable pagination and retrieve all results, set pageNumber to 0.
pageRowCount (Integer): In conjunction with paginated API’s, this parameter defines the number of records per page. The default value is 25. Adjusting pageRowCount allows you to control the volume of data returned in a single request.

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 Content 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:

400 Bad Request: The request was improperly formatted or contained invalid parameters, preventing the server from processing it.
401 Unauthorized: The request lacked valid authentication credentials or the credentials provided do not grant access to the requested resource.
404 Not Found: The requested resource was not found on the server.
500 Internal Server Error: The server encountered an unexpected condition that prevented it from fulfilling the request.

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 Content 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:

Data Presentation: Depending on the nature of the request, the service returns either a single data object or an array of objects encapsulated within the JSON envelope.
- Creation and Update API: These API routes return the unmodified (pure) form of the data object(s), without any associations to other data objects.
- Delete API: Even though the data is removed from the database, the last known state of the data object(s) is returned in its pure form.
- Get Requests: A single data object is returned in JSON format.
- Get List Requests: An array of data objects is provided, reflecting a collection of resources.
Data Structure and Joins: The complexity of the data structure in the response can vary based on the API’s architectural design and the join options specified in the request. The architecture might inherently limit join operations, or they might be dynamically controlled through query parameters.
- Pure Data Forms: In some cases, the response mirrors the exact structure found in the primary data table, without extensions.
- Extended Data Forms: Alternatively, responses might include data extended through joins with tables within the same service or aggregated from external sources, such as ElasticSearch indices related to other services.
- Join Varieties: The extensions might involve one-to-one joins, resulting in single object associations, or one-to-many joins, leading to an array of objects. In certain instances, the data might even feature nested inclusions from other data objects.

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:

200 OK: This status code is returned for successful GET, LIST, UPDATE, or DELETE operations, indicating that the request has been processed successfully.
201 Created: This status code is specific to CREATE operations, signifying that the requested resource has been successfully created.

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": []
}

products: In this example, this key contains the actual response content, which may be a single object or an array of objects depending on the operation performed.

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.

Authentication Specific Routes

Common Routes

Route: currentuser

Route Definition: Retrieves the currently authenticated user’s session information.

Route Type: sessionInfo

Access Route: GET /currentuser

Parameters

This route does not require any request parameters.

Behavior

Returns the authenticated session object associated with the current access token.
If no valid session exists, responds with a 401 Unauthorized.

// Sample GET /currentuser call
axios.get("/currentuser", {
  headers: {
    "Authorization": "Bearer your-jwt-token"
  }
});

Success Response Returns the session object, including user-related data and token information.

{
  "sessionId": "9cf23fa8-07d4-4e7c-80a6-ec6d6ac96bb9",
  "userId": "d92b9d4c-9b1e-4e95-842e-3fb9c8c1df38",
  "email": "user@example.com",
  "fullname": "John Doe",
  "roleId": "user",
  "tenantId": "abc123",
  "accessToken": "jwt-token-string",
  ...
}

Error Response 401 Unauthorized: No active session found.

{
  "status": "ERR",
  "message": "No login found"
}

Notes

This route is typically used by frontend or mobile applications to fetch the current session state after login.
The returned session includes key user identity fields, tenant information (if applicable), and the access token for further authenticated requests.
Always ensure a valid access token is provided in the request to retrieve the session.

Route: permissions

*Route Definition*: Retrieves all effective permission records assigned to the currently authenticated user.

*Route Type*: permissionFetch

Access Route: GET /permissions

Parameters

This route does not require any request parameters.

Behavior

Fetches all active permission records (givenPermissions entries) associated with the current user session.
Returns a full array of permission objects.
Requires a valid session (access token) to be available.

// Sample GET /permissions call
axios.get("/permissions", {
  headers: {
    "Authorization": "Bearer your-jwt-token"
  }
});

Success Response

Returns an array of permission objects.

[
  {
    "id": "perm1",
    "permissionName": "adminPanel.access",
    "roleId": "admin",
    "subjectUserId": "d92b9d4c-9b1e-4e95-842e-3fb9c8c1df38",
    "subjectUserGroupId": null,
    "objectId": null,
    "canDo": true,
    "tenantCodename": "store123"
  },
  {
    "id": "perm2",
    "permissionName": "orders.manage",
    "roleId": null,
    "subjectUserId": "d92b9d4c-9b1e-4e95-842e-3fb9c8c1df38",
    "subjectUserGroupId": null,
    "objectId": null,
    "canDo": true,
    "tenantCodename": "store123"
  }
]

Each object reflects a single permission grant, aligned with the givenPermissions model:

**permissionName**: The permission the user has.
**roleId**: If the permission was granted through a role. - **subjectUserId**: If directly granted to the user.
**subjectUserGroupId**: If granted through a group.
**objectId**: If tied to a specific object (OBAC).
**canDo**: True or false flag to represent if permission is active or restricted.

Error Responses

401 Unauthorized: No active session found.

{
  "status": "ERR",
  "message": "No login found"
}

500 Internal Server Error: Unexpected error fetching permissions.

Notes

The /permissions route is available across all backend services generated by Mindbricks, not just the auth service.
Auth service: Fetches permissions freshly from the live database (givenPermissions table).
Other services: Typically use a cached or projected view of permissions stored in a common ElasticSearch store, optimized for faster authorization checks.

Tip: Applications can cache permission results client-side or server-side, but should occasionally refresh by calling this endpoint, especially after login or permission-changing operations.

Route: permissions/:permissionName

Route Definition: Checks whether the current user has access to a specific permission, and provides a list of scoped object exceptions or inclusions.

Route Type: permissionScopeCheck

Access Route: GET /permissions/:permissionName

Parameters

Parameter	Type	Required	Population
permissionName	String	Yes	`request.params.permissionName`

Behavior

Evaluates whether the current user has access to the given permissionName.
Returns a structured object indicating:
- Whether the permission is generally granted (canDo)
- Which object IDs are explicitly included or excluded from access (exceptions)
Requires a valid session (access token).

// Sample GET /permissions/orders.manage
axios.get("/permissions/orders.manage", {
  headers: {
    "Authorization": "Bearer your-jwt-token"
  }
});

Success Response

{
  "canDo": true,
  "exceptions": [
    "a1f2e3d4-xxxx-yyyy-zzzz-object1",
    "b2c3d4e5-xxxx-yyyy-zzzz-object2"
  ]
}

If canDo is true, the user generally has the permission, but not for the objects listed in exceptions (i.e., restrictions).
If canDo is false, the user does not have the permission by default — but only for the objects in exceptions, they do have permission (i.e., selective overrides).
The exceptions array contains valid UUID strings, each corresponding to an object ID (typically from the data model targeted by the permission).
