Generate PDFs (Batch)
AI-generatedSummary
Queues an asynchronous batch of PDFs by sending one JSON data object per incoming item to the selected Cellystial template. Optionally include a Document ID on every row to identify each result and set its filename, and a webhook URL for completion notifications.
Inputs
- Template Name or ID (required) — Select the template or provide its ID; the same template is used for the whole batch.
- Row Data (required) — A JSON object for this item's PDF. Defaults to the full incoming item; each incoming item becomes one batch row.
- Document ID — Optional identifier for this row, echoed in batch results. Set it on every row or leave it blank on every row; mixing the two causes an error.
- Output Filename — Optional filename for this row's PDF. Used only when Document ID is set; otherwise the service's default naming applies.
- Completion Webhook URL — Optional URL that Cellystial calls when batch generation finishes.
Output shape
A single n8n item containing the batch API response, including the batch ID for use with Get Batch Status.
The operation queues the batch asynchronously and does not return the generated PDF files. It requires at least one incoming item; Row Data must parse as a JSON object. With Document IDs, every row must have one. Errors stop execution unless Continue On Fail is enabled, in which case the output contains an error field.
