WELCOMEHOME (NORTHERN MORTGAGE) API INTEGRATION
Accessing Borrower Loan Files, Documents & Milestone Status from the SimpleNexus Mortgage Client
============================================================
INTRODUCTION
--------------------
WelcomeHome is the borrower-facing mortgage app published by Northern
Mortgage Services, LLC (NMLS 130662), built as a tenant instance of the
SimpleNexus mortgage client — the point-of-sale platform acquired by
nCino in 2022 and rebranded as the nCino Mortgage Suite. While the app's
calculators run locally on the phone, the real value for integrators
sits behind the login: the borrower's loan application file, scanned
documents, outstanding conditions, milestone status updates, and loan
officer/agent contact records, all hosted on Northern Mortgage's
SimpleNexus tenant (package id com.simplenexus.loans.client.s__70857).
For lenders, CRMs, document management platforms and referral partners
that are not natively wired into SimpleNexus / nCino Mortgage Suite,
an authorized API integration unlocks real-time access to this data —
turning a closed mobile client into a structured, machine-readable data
source under proper borrower or lender consent.
============================================================
SUPPORTED API FEATURES
--------------------
Loan application file retrieval (borrower 1003 data, per loan
and per borrower, synced from the SimpleNexus / nCino tenant)
Document upload access — scanned paystubs, bank statements,
IDs and other condition documents, returned with doc-type labels
Conditions & outstanding tasks tracking, returned as
structured per-condition records
Milestone & loan status events pushed from the lender's
system of record (e.g., Processing, Underwriting, Closing)
Loan officer and real-estate agent contact data tied to
each loan file
Loan program / scenario detection (Conventional, FHA 203B/203K,
USDA, VA) for pipeline tagging and analytics
OAuth 2.0 bearer-token authentication with refresh-token
handling for stable, long-running data syncs
============================================================
USE CASES & APPLICATIONS
--------------------
[1] CRM Integration & Borrower Sync
Push WelcomeHome application data automatically into CRMs
that lack native SimpleNexus / nCino connectivity
Trigger marketing and follow-up workflows the moment a
borrower submits or updates their loan application
Keep borrower contact and loan-status fields aligned across
multiple systems without manual re-entry
[2] Pipeline Reporting & Branch Management
Mirror live loan milestone events (Processing, Underwriting,
Closing) into internal dashboards
Give branch managers real-time pipeline visibility without
manual exports from the SimpleNexus tenant
Tag loans by program type (FHA, VA, USDA, Conventional) for
performance analytics
[3] Document Management & Conditions Automation
Automatically ingest borrower-uploaded documents (paystubs,
statements, IDs) into a central document repository
Map incoming files to the correct loan-condition labels
instead of handling them as a flat blob list
Drive automated borrower-nudge campaigns from the live
conditions/tasks list
[4] Referral Partner & Agent Portals
Give real-estate agents secure, consented visibility into
their referred borrower's loan status
Build lightweight partner dashboards that reflect milestone
updates without exposing full loan files
Maintain compliance by scoping each partner's access to only
their own borrowers' data
[5] Cross-Platform Mortgage Data Unification
Combine WelcomeHome / SimpleNexus data with other mortgage
POS platforms such as Floify, Blend, Maxwell, BeSmartee,
Loanzify and Encompass
Standardize loan file, document and milestone formats across
multiple lender tech stacks
Build a unified data layer for multi-lender or multi-brand
mortgage operations
============================================================

============================================================
CONCLUSION
--------------------
WelcomeHome's real value lies behind the login screen — in the loan
application data, documents, conditions and milestone events stored on
Northern Mortgage's SimpleNexus / nCino Mortgage Suite tenant. With an
authorized, consent-based integration, lenders, CRMs, document
platforms and referral partners can turn this data into a live,
structured feed that powers automation, reporting and unified
mortgage-data pipelines.
