Abstract: A system for generating personalized uniform resource locators for data collection. The system may include a processor and a memory device storing instructions that configure processor to perform operations. The operations may include configuring an application programming interface (API) to communicate with a repository server storing information from real estate properties, retrieving (using the API) records of real estate properties and identifying a subset of users with upcoming reporting duties. The operations may also include generating personalized URLs encoding client identifiers (IDs) and account IDs for users in the subset, transmitting the personalized URLs to client devices, and receiving a website request through one of the personalized URLs. The operations may also include determining a client ID and an account ID embedded a personalized URL; and generating a data collection website comprising a collection graphical user interface (GUI).
