Hello Soni,

I do not know if you still need help with this issue but I can share my experience with you.

To save data in the database what I did was to create an entity with the same attributes that the structures required by the calendar has. After creating an event with the CreateEvent Client Action, assign all the fields of the structure to the entity on the database and call to the Server Action CreateEvent (the one of the entity in the db).

Hope that helps a little.

Best regards
