How is this guide?
post_v1_company_documents
GenerateDocuments renders the formation documents for the chosen structure and jurisdiction, ingests each into the org's data room, and submits the state filing through the filing seam.
post_v1_company_esign_complete
CompleteEsign records whether the formation documents have been signed. It consults the e-signature provider, which a real provider's webhook drives; the signal is idempotent.
