Abstract: A computing device (e.g., a server, a cloud-based device, a request management device, etc.), for example, such as a computing device associated with a vehicle dealership and/or the like, may receive a plurality of transaction requests, such as requests to purchase, lease, and/or finance a vehicle. Each transaction request may include user information associated with the transaction, such as a phone number, a home/mailing address, email address, a credit score, vehicle trade-in information, and/or any other data elements. For each transaction request, the computing device may invoke one or more microservices to verify data elements of user information and use responses from the microservices to rank each transaction requests on its potential to progress to a completed transaction.
