SGS API Integration Specification — Data Exchange Protocol

Overview

This document outlines the technical specifications for the API-based data exchange between DaedArch Corporation (hereinafter referred to as "DaedArch") and SGS (hereinafter referred to as "the Organization"). The primary objective of this integration is to facilitate the seamless transfer of data related to carbon market verification, ensuring compliance with the Organization's standards and requirements.

Scope

The API will allow DaedArch to submit sensor-based Measurement, Reporting, and Verification (MRV) data to SGS for verification in both voluntary and compliance carbon markets. This integration will also support the Organization's sustainability services division focused on Environmental, Social, and Governance (ESG) assurance.

Intended Audience

This document is intended for technical reviewers, developers, and compliance officers involved in the integration process. It provides detailed instructions on authentication, data endpoints, data models, error handling, and rate limits.

Authentication

Authentication Method

The API shall utilize OAuth 2.0 for authentication. All requests to the SGS API must include a valid access token in the Authorization header.

Token Acquisition

  1. Client Credentials Grant Type: DaedArch shall obtain an access token by sending a POST request to the token endpoint.

Endpoint: https://api.sgs.com/oauth/token

Request Format: `http POST /oauth/token HTTP/1.1 Host: api.sgs.com Content-Type: application/x-www-form-urlencoded

grant_type=client_credentials& client_id=& client_secret= `

Response Format: `json { "access_token": "", "token_type": "Bearer", "expires_in": 3600 } `

  1. Token Expiration: The access token shall expire after 3600 seconds. DaedArch must implement a mechanism to refresh the token prior to expiration.

Authorization Header

All subsequent API requests shall include the following Authorization header:

`http Authorization: Bearer `

Endpoints

Base URL

The base URL for all API requests shall be:

` https://api.sgs.com/v1 `

Response Format: `json { "status": "success", "message": "MRV data submitted successfully", "data_id": "" } `

Error Response Format: `json { "status": "error", "message": "", "code": } `

Data Retrieval Endpoint

Endpoint: Retrieve MRV Data

URL: /mrv-data/{data_id}

Method: GET

Request Format: `http GET /v1/mrv-data/{data_id} HTTP/1.1 Host: api.sgs.com Authorization: Bearer `

Response Format: `json { "status": "success", "data": { "project_id": "", "sensor_id": "", "timestamp": "", "data": { "co2_emissions": , "methane_emissions": , "nitrous_oxide_emissions": , "energy_consumption": }, "location": { "latitude": , "longitude": }, "verification_chain": { "certification_id": "", "auditor_id": "", "audit_timestamp": "" } } } `

Verification Status Endpoint

Endpoint: Check Verification Status

URL: /verification-status/{data_id}

Method: GET

Request Format: `http GET /v1/verification-status/{data_id} HTTP/1.1 Host: api.sgs.com Authorization: Bearer `

Response Format: `json { "status": "success", "verification_status": { "data_id": "", "status": "", // e.g., "pending", "verified", "rejected" "comments": "" } } `

Data Models

MRV Data Model

The MRV data model shall conform to the following schema:

`json { "project_id": "string", "sensor_id": "string", "timestamp": "string", "data": { "co2_emissions": "float", "methane_emissions": "float", "nitrous_oxide_emissions": "float", "energy_consumption": "float" }, "location": { "latitude": "float", "longitude": "float" }, "verification_chain": { "certification_id": "string", "auditor_id": "string", "audit_timestamp": "string" } } `

Verification Status Model

The verification status model shall conform to the following schema:

`json { "data_id": "string", "status": "string", "comments": "string" } `

Error Handling

Common Error Codes

The API shall return the following common error codes with corresponding messages:

| Error Code | HTTP Status | Message Description | |------------|-------------|-----------------------------------------| | 400 | Bad Request | Invalid request format or missing fields | | 401 | Unauthorized| Invalid or expired access token | | 403 | Forbidden | Access denied for the requested resource | | 404 | Not Found | Resource not found | | 500 | Internal Server Error | Unexpected error occurred |

Error Response Structure

All error responses shall contain the following structure:

`json { "status": "error", "message": "", "code": } `

Rate Limits

Rate Limiting Policy

To ensure fair usage of the API, the following rate limits shall apply:

  • Requests per minute: A maximum of 100 requests per minute per client.
  • Requests per hour: A maximum of 500 requests per hour per client.

Rate Limit Response

When a client exceeds the rate limit, the API shall respond with the following HTTP status code and message:

HTTP Status: 429 Too Many Requests

Response Format: `json { "status": "error", "message": "Rate limit exceeded. Please try again later.", "code": 429 } `

Conclusion

This API Integration Specification serves as a comprehensive guide for the technical integration between DaedArch and SGS. All stakeholders involved in the implementation of this integration shall adhere to the outlined specifications, ensuring compliance with SGS's standards and requirements for verification in carbon markets.

It is imperative that DaedArch implements robust error handling, authentication, and data validation mechanisms to maintain the integrity and security of the data exchanged between the two systems. The successful integration of these systems will facilitate enhanced monitoring and verification processes, contributing to the overall goals of sustainability and compliance within carbon markets.
