Saasu Rest API
Saasu’s comprehensive application programming interface (API) allows other software and web applications to interact with Saasu. Just as humans do by creating, reading, updating and deleting transactions. Our API framework has been built in the REST style. All calls are conducted through unified HTTP methods: GET, POST, and DELETE. You’ll need a basic understanding of XML and Schema.
