API is an acronym for an Application Programming Interface. The Assignr API is a software interface that allows software applications to read or update information in the Assignr system. Software developers can write scripts to retrieve or update information in the Assignr system, such as games, officials, availability, game reports, and much more.
Access to the Assignr API is available for organizations who use Assignr to manage their referees and umpires. Companies or individuals who are interested in writing an integration with Assignr are also able to request access to our API.
