12. Authentication is achieved with a challenge response handshake. GET r25ws/servlet/wrd/run/login.xml Returns a string, that must be hashed with the password The hash format is: – hash({hash(password)}:{challenge string}) – The ‘:’ needs to be included in the hash. I found this misleading in the documentation.

13. To perform a room search: We created a temporary search, and run it via Web Services. This is as powerful as building a search in the R25 client. You could easily use this to create custom reports, or custom calendar display on the web. Searches follows the same conventions as the rest of R25’s web services. Room Search

14. After the end user submits the form, we create the event. The new event: Is associated with the appropriate contact. Has a default state of ‘Draft’. Has an exact room match, which reduces human error. Saves category data. Category data matches our public website’s news categories. Event Creation
