preparation: In ` https://calendar.google.com/calendar/ ` 1. Create 2 google calendars. (testCal1, and testCal2) 2. Create an event "past_event" in calendar "testCal2": Extract event id: 3. Double click on created event in google calendar -> you will get uri (e.g 'https://calendar.google.com/calendar/b/5/r/eventedit/ZnZ1azJzaWlwZjdvOGQybDJsZ3VucTI2MmMgZWNjaDlpMTY5cjV1NzdlZGw3NTJwOTFyNjBAZw?tab=rc1' 4. Take string after last slash ('ZnZ1azJzaWlwZjdvOGQybDJsZ3VucTI2MmMgZWNjaDlpMTY5cjV1NzdlZGw3NTJwOTFyNjBAZw?tab=rc1') and decode it here: https://www.base64decode.org/ 5. take fist part of decoded result (there are 2 parts,separted by either '_' or ' ') that is event id (see extracted-event-id below) In syndesis: 1. Put credentials for google calendar (Settings -> Google Calendar -> Client Id + Client Secret related to your account) 2. Create connection for google calendar (Connections -> Create connections -> select Google Calendar type -> Connect to Google calendar (select your account)) Create integration: 3. (from) 'Timer' -> Simple -> 1 min. 4. (to) 'Google Calendar' -> "Create event" -> event_title=new_event, calendar_name=testCal1 5. Add middle step 'Google Calendar' -> "Get a specific event" -> calendar_name=testCal2, event_id=extracted-event-id(see preparation) 6. add datamapper step between 2 google calendars steps, and map start_time -> start_time, end_time -> end_time (just these 2 are problematic, e.g start_date and end_date are OK) from past_event to new_event. 7. publish integration
