Mortgage Insurance Activation API
MISMO published the Mortgage Insurance (MI) Activation API Implementation Guide (iGuide) and sample files as a Candidate Recommendation in July of 2025.
The Mortgage Insurance (MI) Activation API iGuide and related sample files provide lenders with a streamlined method of activating the MI Commitment by allowing lenders to send closing date information to MI companies without leaving their system of record, ensuring greater efficiency and accuracy. The iGuide and sample files are based on Version 3.5 of the MISMO Reference Model.
What It Includes
Changes to the MI Activation API iGuide and samples files include corrections to typographical errors, updates to comments, conditionality, and the addition of two object references.
