The GRESB API, currently only available for the Real Estate Assessment, is meant for submitting the data of the assessment. Data submitted through the API goes to the GRESB Asset Portal where a user can aggregate their asset-level data to the portfolio-level assessment. The aggregated data goes to the Performance Component of the Real Estate Assessment and covers the majority of the reporting requirements. Qualitative data can be submitted directly to the Management & Development Component of the Real Estate Assessment.
GRESB Assessment Partners at the Global and Premier levels are eligible to connect to the GRESB Portal via an API (additional terms and fees required). Each submission via the API also incurs a usage fee. Partners who have successfully established this API capability are designated as GRESB API Partners in our Partner Directory. Use of the GRESB API is only available when tied to a specific GRESB API Partner account in the GRESB Portal. This allows access token creation and provides access to the API endpoints.
