[FEAT]: API Endpoint for Super Admin to Get All Organizations with Pagination (page, limit, offset)

[kobiowuquadri]

Description

Implement an API endpoint to allow a super admin to retrieve all organizations with pagination (page, limit, offset).

Endpoint Feature

• This endpoint enables a super admin to retrieve a list of all organizations with pagination support.
• The endpoint will require authentication and authorization checks to ensure only SUPER_ADMIN users can access it.

Acceptance Criteria

• The endpoint should be accessible at GET /api/v1/organisations
• The endpoint should accept HTTP GET requests.
• The endpoint should return a paginated list of organizations.
• The endpoint should support pagination with parameters such as page, limit, and offset.
• It will return the correct error message if the query fails.

Request Example:

• GET /api/v1/organisations?page=1&limit=10&offset=0

Response Example

• On successful retrieval of the organizations, the API should return a 200 OK status code. The response body should contain a paginated list of organizations:

{
  "status": "success",
  "status_code": 200,
  "data": [
    {
      "id": 1,
      "name": "Organization Name",
      "email": "[email protected]",
      "industry": "Industry",
      "type": "Type",
      "country": "Country",
      "address": "Address",
      "state": "State"
    },
    // More organizations...
  ],
  "pagination": {
    "page": 1,
    "limit": 10,
    "total": 50
  }
}

• If no organizations are found, the API should return a 404 Not Found status code with an appropriate message:

{
  "status": "unsuccessful",
  "status_code": 404,
  "message": "No organizations found."
}

Data Validation

Input Validation:

• Confirm that the pagination parameters (page, limit, offset) are valid integers.

Example: If the parameters are invalid, return a 400 status code with an error message.

{
  "status": "unsuccessful",
  "status_code": 400,
  "message": "Invalid pagination parameters."
}

Output Validation:

• Ensure the response format is correct and includes appropriate status codes and messages.
• If there is an error in retrieving the organizations (e.g., database connection issues), the API should return a 500 Internal Server Error status code with an appropriate message.

{
  "status": "unsuccessful",
  "status_code": 500,
  "message": "Failed to retrieve organizations. Please try again later."
}

Error Handling

Error Responses:

• Define error responses for common failure scenarios.
• Example: If database connection fails, return a 500 status code with an error message.

Edge Cases

• Consider edge cases such as invalid pagination parameters and database connection issues.
• Example: Handle scenarios where the database connection is temporarily unavailable.

Performance and Security

Performance Considerations:

• Review potential performance implications and optimize the API for efficiency.
• Example: Implement caching to reduce database load for frequently accessed organization details.

Security Concerns:

• Address security considerations such as data sanitization.
• Example: Sanitize user inputs to prevent injection attacks.

Documentation

API Documentation:

• Ensure that API documentation is updated to include details about the new endpoint, request/response formats, error handling, and authorization requirements.

Technical Notes

• Include any additional technical notes or considerations.

Testing Requirements
Unit Tests:

• Write unit tests to validate input data and response formats.

Integration Tests:

• Ensure end-to-end functionality is tested with integration tests.

Dependencies and Impact
Dependencies:

• Identify dependencies on other tasks or systems.

Impact Analysis:

Assess the potential impact on other features or components, ensuring that existing functionality is not disrupted.
