Export the measurement data for a measurement batch (by measurement-batch id).
Producer sign-off. The producer (issuer) approves the completed, measured-and-verified workflow, clearing it for minting. Sign-off steps are likely TFA-gated — confirm against your environment.

}
After a measurement batch is created and the measurer is engaged, the measurer reads the batch's assets, computes emissions/standard data, and writes the results back into EarnDLT through the /graphql endpoint. The trigger differs by measurer; the write-back is the same GraphQL mutation for both:
| Measurer | Standard | Trigger | Write-back |
|---|---|---|---|
| Project Canary | OGCI | EarnDLT calls Project Canary (POST /measurement-batch/call-measurer). Project Canary collects and collates the data, then calls back into EarnDLT’s /graphql. | AddStandard mutation |
| Validere | NGSI | EarnDLT does not call Validere’s API — an email notification is sent. Validere collects and collates the data, then calls EarnDLT’s /graphql. | AddStandard mutation |
In both cases the measurer first reads the batch and its assets with GetMeasurementBatch, then writes standard/emissions results per asset with multipleAssetStandardAdd (AddStandard).
GetMeasurementBatch — read a measurement batch and its assets (production data, pollutant source, energy quantities) to know what to measure. assetOptions paginates the assets.

AddStandard (multipleAssetStandardAdd) — write measured standard/emissions results back to EarnDLT, one entry per asset. The update.items[] envelope is shared; each item carries the asset _id, an optional scope2 electricity block, and a standard body whose exact shape is supplied by the measurer and varies by standard (OGCI vs NGSI — see below).

Attach files to the measurement batch step. The files array is required and must be non-empty.

"profileId": "<profileId>",
"workflowId": "<workflowId>",

Approve the measurement batch step. The access token must reflect a completed TFA step.

Create a minting contract from an approved batch. Use the returned contract._id as mintingContractId in the next step.

A complete walkthrough of the RNG production flow on staging — from login through minting tokens. An RNG production batch carries a data file and moves through a measurement step (add files → approve) before minting; each batch exposes a workflowId (from batch.workflows) that the measurement and minting requests reference. Files are uploaded first via POST /file/temporary-upload and referenced by their returned _id.
DISABLE_REQUIRE_TFA is set in the environment.If the account uses two-factor authentication, this step triggers delivery of a code before you call login. Inspect the response to know whether you must supply tfaCode in the next step.
Obtain accessToken and refreshToken. Send Authorization: Bearer <accessToken> on all following requests. Omit tfaCode when 2FA does not apply.
Discover which organizations the user can act under. Pick an organization ID from the response and send it as the x-active-organization-id header on all subsequent requests to scope permissions to that organization.
Resolve issuer/producer profile UUIDs required for batch creation and measurement steps. Choose the profileId that corresponds to the role for your scenario.
Before or after creating a batch, inspect existing minting contracts. You can query without a workflowId to browse, or return here after step 9 with the resolved ID.
Stage the Excel file; the API returns temporary file metadata including _id.
documentIdXlsx = files[0]._id → used in step 8
Stage the evidentiary PDF using the same endpoint.
documentIdPdf → used in step 10
Create the batch from the LCA file uploaded in step 6.
batchId = batch._id → used in steps 9, 12, 13
Load the batch and read the workflow identifier used by measurement and minting APIs. Use the relevant entry in batch.workflows — its _id is the workflowId for downstream calls. You can now repeat step 5 with this ID.
workflowId = batch.workflows[n]._id → used in steps 10–13
Link supporting documents to the measurement workflow.
Approve the measurement batch for the workflow. The access token must reflect a completed TFA step.
Push the approved batch toward on-network processing.
Create the minting contract for this batch and workflow.
mintingContractId = contract._id → used in step 14
Execute the final mint for the contract created in step 13.
End-to-end walkthrough for minting natural-gas QETs under the NGSI standard — from registering wells through minting. The measurement standard and the measurer/verifier parties are chosen when the measurement batch is created; the standard can be NGSI, OGCI, or (verify-only) OF, and this example uses NGSI. Creating the measurement batch returns a workflowId that threads through measurer, verifier, and producer sign-off and into minting. Files (wells, monthly data, verification evidence) are uploaded first via POST /file/temporary-upload and referenced by their returned _id.
Upload a spreadsheet of wells and receive a temporary file id. (Shared endpoint — see Network API File Uploads.)
Register the wells for your organization, referencing the uploaded file.
Upload the month's production data file; keep the returned _id.
Create the batch for a given month/year and profile. Save the returned batch _id as batchId.
Attach the NGSI standard and the measurer + verifier parties. Save the returned workflowId. (OGCI and OF variants exist — see the Natural Gas Production API reference.)
The measurer is engaged to run measurement for the workflow. For NGSI (Validere) an email notification is sent automatically — no API call is made. For OGCI (Project Canary), EarnDLT instead calls the measurer via POST /measurement-batch/call-measurer.
The measurer reads the batch assets with the GetMeasurementBatch query, then writes the measured standard/emissions results back per asset via the AddStandard (multipleAssetStandardAdd) GraphQL mutation. For NGSI (Validere) this is triggered by an email notification rather than an API call; for OGCI (Project Canary) it follows the call-measurer step. See Measurer Integration (GraphQL) for the full query and mutation.
The measurer approves the measurement result, advancing the workflow to verification.
The verifier issues a verification statement, attaches evidence, and approves.
The producer (issuer) approves the measured-and-verified workflow, clearing it for minting.
Submit the approved batch/workflow to the network as QET.
Create the minting contract; save the returned contract _id as mintingContractId.
Mint the natural-gas QETs for the contract (NGSI / OGCI / OF per the workflow's standard).
