   Navigation and example consistency

   The developer hub and document API page now follow the published multipart upload, job ID and completion-status flow. Chapters distinguish contract availability, webhook handling and errors.

   These are website documentation changes, not a service API version or release announcement.

   v1 documentation alignment

   The quickstart uses the published invoice upload endpoint, multipart fields and result lookup by job ID. Webhook guidance uses the published completion event and signature header. Error guidance separates failed requests, failed jobs and uncertain upload acceptance.

Before adopting a contract change.

Use the API version and response fields agreed for your integration. Validate changes with representative documents before changing a production consumer, and retain the source and job identifier for reconciliation.

Service release history, deprecation dates and migration commitments belong to your agreed support contract.
