Prepared for SGS. Api Integration Spec. Draft in review.
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.
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.
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.
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.
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=`
Response Format: `json { "access_token": "`
All subsequent API requests shall include the following Authorization header:
`http Authorization: Bearer `
The base URL for all API requests shall be:
` https://api.sgs.com/v1 `
URL: /mrv-data
Method: POST
Request Format: `http POST /v1/mrv-data HTTP/1.1 Host: api.sgs.com Content-Type: application/json Authorization: Bearer
{ "project_id": "`
Required Fields:
project_id: Unique identifier for the project (string, required).sensor_id: Unique identifier for the sensor (string, required).timestamp: ISO 8601 formatted timestamp of data collection (string, required).data: Object containing environmental data metrics (required).co2_emissions: CO2 emissions in metric tons (float, required).methane_emissions: Methane emissions in metric tons (float, required).nitrous_oxide_emissions: Nitrous oxide emissions in metric tons (float, required).energy_consumption: Energy consumption in kWh (float, required).location: Object containing geographical coordinates (required).latitude: Latitude of the sensor location (float, required).longitude: Longitude of the sensor location (float, required).verification_chain: Object containing verification details (required).certification_id: Unique ID of the certification (string, required).auditor_id: Unique ID of the auditor (string, required).audit_timestamp: ISO 8601 formatted timestamp of the audit (string, required).Response Format: `json { "status": "success", "message": "MRV data submitted successfully", "data_id": "`
Error Response Format: `json { "status": "error", "message": "`
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": "`
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": "`
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" } } `
The verification status model shall conform to the following schema:
`json { "data_id": "string", "status": "string", "comments": "string" } `
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 |
All error responses shall contain the following structure:
`json { "status": "error", "message": "`
To ensure fair usage of the API, the following rate limits shall apply:
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 } `
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.
