Multifamily Application Programming Interfaces (APIs)

We are excited to introduce new API capabilities and features in Q3. Our upcoming Insurance API will address flood requirements, and we are also developing an API versioning solution.

Fannie Mae Multifamily APIs were developed to improve your business

Application programming interfaces (APIs) have become integral across the entire technology landscape. For Multifamily lenders, APIs are being recognized as a critical technology that provides immense potential to automate processes,  improve opportunities and accuracy, as well as reduce costs and workloads.

At Fannie Mae, we strive to improve your experience and that of your borrowers. Our dedicated Multifamily teams are here to collaborate with you, ensuring seamless integration as you expand and elevate your business through the implementation of our Multifamily APIs.

Utilize our powerful APIs, thoroughly crafted to meet the specific requirements of our lenders, available on the Fannie Mae Developer Portal.
