Every row keeps its own result.
START WITH THE DATA YOU HAVE

Bring the rows.
Skip the repeated setup.

Upload a CSV in Studio or send a JSON array through the API. Column names map to published fields, while batch defaults fill values shared by every row.

Rows normalized
Map once

Studio suggests matching columns and lets you ignore data the visual does not need.

Set shared defaults

Campaign, language or media can be applied once and overridden only where needed.

Keep payloads clear

Stable media references replace repeated base64 payloads and oversized rows.

ROW-LEVEL PREFLIGHT

Check the data
before compute starts.

Required values, types and media references are validated against the pinned template version. Valid rows continue while a bad row stays visible with a useful reason.

  • Required and typed fields
  • Media references and output kind
  • Exact published template version

VISIBLE WHILE IT RUNS

One batch.
Independent outcomes.

A batch is not one opaque job. Every row moves through queued, rendering, completed or failed states independently, so partial success remains useful.

Correct only failed rowsApply row-specific values without rerendering completed work.
Keep the source pinnedCorrections continue against the same template version.
Cancel deliberatelyStop remaining work while preserving completed outputs.
BOUNDED BATCHES · CONTINUOUS PRODUCTION

From a short list
to thousands of outputs.

Batch size follows the active plan. Large feeds can be divided into traceable runs with stable caller keys, predictable status and no duplicate submissions.

COLLECT THE RUN

Take the files.
Keep the operational record.

Studio packages successful artifacts with human-readable and machine-readable reports. API workflows can follow batch status and hand completed results to the next system.

Completed files in one Studio download.

CSV report

Every row with status, render ID and error.

THE DEVELOPER PATH

Submit the rows.
Keep the request responsive.

The API returns an asynchronous batch immediately. Poll its operation ID for row-level results or cancel work that should no longer continue.

  • JSON items or CSV in one request
  • Batch and row idempotency keys
  • Version-pinned execution
  • Row-level status and artifact references
