The Guaranty Remittance API will enable lenders to submit a closed loan for guaranty, allowing VA to evaluate the final closing disclosure and baseline loan information and provide feedback on VA policy conformance, calculate the appropriate funding fee amount, and return the Loan Guaranty Certificate (LGC) through the lender’s Loan Origination System (LOS). The API will first perform a series of data integrity checks which compare the data being submitted in the ULAD, UCD and API request against data that was previously submitted when the appraisal was ordered. Inconsistent data may result in critical errors. Additional advisory checks are then performed against VA policies and procedures. The funding fee will be calculated, payment remittance process through pay.gov initiated, and the LGC generated.
The Guaranty Remittance API is targeted for release in Q2 2025.
NOTE: VA encourages the lender community to migrate to the Application Programming Interface (API) technology, as the VA anticipates moving from the User Interface (UI) solutions in the future.
