Welcome to the eClose API

The eClose API creates closings in Snapdocs, uploads documents to them, and tracks every milestone from drawn documents through signing and completion. It spans two integration types: LOS-driven closing workflows and POS-driven signer engagement.

From your Loan Origination System (LOS), create closings and upload documents, receive status updates, submit revised documents, and download signed packages. From your Point of Sale (POS) system, listen for major events — documents ready to review, eSigning available — and prompt signers to act from your own experience.

Platform behavior is documented once, in Getting Started: authentication, environments, the Subscriptions API, webhook security, and testing. This tab covers what's specific to eClose:

• Introduction — the Postman collection and testing walkthroughs, event payloads, errors, and the glossary.
• Security — signer SSO (OAuth 2.0 and SAML), SCIM role management, and company user validation.
• Lender Integration — building closings into your LOS: architecture, scope, closing creation, redraws, statuses, and scanbacks.
• Borrower Engagement (POS) Integration — event-driven signer workflows for POS systems.

Every endpoint's details live in the API Reference tab.
