MISMO Seeks Public Comment on Updated Mortgage Insurance Activation API

MISMO, the real estate finance industry’s standards organization, announced it is seeking public comment on revisions to the previously published Mortgage Insurance (MI) Activation API Implementation Guide (iGuide) and sample files. The 30-day public comment period runs through June 5, 2025.

“The 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,” said MISMO Acting President Rick Hill.

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. 

The public comment period allows those who participated in the proposal at least 30-days’ notice prior to final release to review and disclose any applicable Patent Rights (as defined by MISMO’s 2018 Intellectual Property Rights Policy).

MISMO requests that any organization that may have any patent or patent applications, or other intellectual property rights that might be infringed upon by an organization that uses or is compliant with these proposed MISMO products to disclose them at this time in writing. All comments and disclosures are due by June 5, 2025 and should be directed to info@mismo.org.
