YouSendIt is the first business content collaboration service to offer an integrated approach for sending, sharing and signing documents online. We have APIs that allow you to integrate and build on core YouSendIt functionality including the ability to send, receive, and track files with ease and security. Whether you have a back-end system that requires the automated generation and sending of reports, a requirement to comply with HIPAA regulations, or a need to send files larger than email limitations, our APIs provide the solution.
