Batch & async jobs

Generate at volume: produce many documents from one template, run resumable statement runs, and drive long-running work through an asynchronous job API with signed webhook callbacks.

Batch generation

Apply one template to many records in a single request — ideal for statement and mailing runs. Choose the packaging:

Separate files returned as a zip archive, or
a single merged PDF.

File names can be derived from data fields, and per-recipient language/formatting is applied. Partial failures are reported per record (record id + reason) so a bad row never fails the whole run.

High-volume statement runs

For very large runs (tens or hundreds of thousands of documents), statement-run mode is checkpointed and resumable — an interrupted run continues from the last completed record. Configurable concurrency and back-pressure protect the engine and the database, and live progress, throughput metrics and a per-record failure export are available.

Asynchronous job API

Submit long-running generation or signing as a job and poll for status or receive a callback:

Submit — the endpoint returns a jobId immediately; a background worker processes it.
Status — poll the job for state (queued, running, succeeded, failed, partial) and progress.
Result — retrieve results by jobId.

Use an idempotency key to avoid duplicate submissions, and set a retention policy for results.

Webhooks

Register a callback URL to be notified when a job completes. Callbacks are signed with an HMAC so your receiver can verify authenticity before acting. See the API reference for endpoints and payloads.
