TextKey's JAVA library allows you to use REST API calls server-side from a Java backend. TextKey is an omni-factor authentication API that uses seven-factors of authentication to provide security for devices ranging from mobile to electronic door locks. TextKey works through using SMS service, unique code, cellular number, UDID, a single use URL, and an optional pin. TextKey uses Rest with a JSON response and SOAP. TextKey is free for ten users, and available for a monthly charge per user thereafter.
BugDigger, a BugsIO bug reporting tool, offers the BugDigger API that can integrate with bug tracking and reporting systems. BugDigger removes the manual, human element from bug reporting and leverages its technology to automatically capture the needed data to accurately report bugs in a given environment. BugDigger aims to take the human error and labor out of bug reporting which enables software developers to rely on accurate reports and fixes instead of uncovering errors in bug reports.
