New datapoint component endpoints and expanded filters
Two new endpoints have been added: GET datapoint components retrieves components that use the specified datapoint, and GET datapoint removal template components retrieves removal template components that use the specified datapoint. The GET components endpoint has been expanded with new filter options, including scope to filter components by scope, ghg_statement_id to filter by GHG statement ID, project_id to filter by project ID, and removal_id to filter by removal ID. Additionally, the GET datapoints endpoint now supports an expanded set of filters for more granular querying of datapoints including all of the above and extending to removal.

Storage Unit endpoint + Storage Locations on Measurement Samples.
  • Endpoints for managing storage units were released in beta. See GET Storage Unit for details.
  • Storage Locations can now also be attached to Measurement Samples on creation.
​
2025-05-21
Standard deviation value optional on PATCH datapoint
The PATCH datapoint endpoint no longer requires a value for standard_deviation.
​
2025-05-14
Storage Locations returned on monitoring requirement resource and location required
Storage locations are now returned in the Project Monitoring Requirements resource. In addition, they now require a latitude and longitude parameter on creation.
​

Process resource deprecated in favour of Removal Template
LCA templates built in Certify can be now retrieved at GET removal templates. This deprecates the Process resource and simplifies the reuse of fixed inputs on removal templates.The process_key and steps fields are now deprecated on POST removals in favour of removal_template_id and removal_template_components. See creating your first removal for details.
​
2025-02-28
Project-scoped components now accept time-based allocation strategies
The POST project component endpoint request body now accepts two new strategies for allocation_strategy: ESTIMATED_PROJECT_LIFETIME and CUSTOM_TIME_PERIOD. The PATCH component endpoint request body now accepts two new strategies for allocation_strategy: ESTIMATED_PROJECT_LIFETIME and CUSTOM_TIME_PERIOD.You have a choice of an ESTIMATED_PROJECT_TONNAGE, ESTIMATED_PROJECT_LIFETIME, CUSTOM_TIME_PERIOD or MANUAL allocation_strategy and can patch the choice in the future if any updates or changes occur.
​
2025-02-04
Removals now allow assignment of labels
The POST removal endpoint now accepts a list of label_ids in the request body. The PATCH removal endpoint now accepts a list of label_ids field in the request body. The GET removal endpoint now returns a list of label_ids field in the response body.Labels are currently an optional field for Removals.
​
2025-01-24
Project-scoped components now require an allocation strategy
The POST project component endpoint now accepts an allocation_strategy in the request body. The PATCH component endpoint now accepts an allocation_strategy field in the request body. The GET component endpoint now returns an allocation_strategy field in the response body.An allocation_strategy is currently a required field for all Project-scoped components. You have a choice of an ESTIMATED_PROJECT_TONNAGE or MANUAL allocation_strategy and can patch the choice in the future if any updates or changes occur.
​
2024-12-13
Datapoints are now associated to projects
The POST datapoint endpoint now accepts a project_id in the request body. The GET datapoint endpoint now returns a project_id field in the response body.The project_id is currently an optional field but will become required in the future. You should therefore ensure that you migrate your code to include the project_id in the request body.
