ASYNC_PDF_GENERATOR node.

Inputs & outputs

Configuration

No configuration.

Example

How it works

ASYNC_PDF_GENERATOR renders a PDF from a template and saves it directly to object storage rather than returning the bytes to the graph. Configure the templateId and a destination storageId, wire a fileName plus all the template variables, and the node generates the document and writes it to storage — producing no output on the graph. Use it for "fire-and-forget" document generation where you just need the file archived.

Example

Scenario: A nightly Workflow generates monthly statements and files them in storage.

1. A loop emits one customer's data per iteration (name, period, totals).
2. Add an ASYNC_PDF_GENERATOR node. Select the statement templateId, set storageId to your statements bucket, and set fileName to e.g. statements/2026-06/cust-553.pdf. Wire the template variables in.
3. The node renders and stores each PDF; continue the loop without waiting on a returned document.

LOOP ──► ASYNC_PDF_GENERATOR (saves to storage)

Unlike PDF_GENERATOR, this node returns nothing on the graph — read the file later with GET_STORAGE_FILE if you need it.
