Creating a flow to automate events from a web calendar to a local calender

Posted on by
Hi There,
 
I am trying to build a flow and I'm struggling with this so I am asking for some help on this.
 
I have a calendar from the web that I am subscribed to. What I want to do is every time an event is created, updated or deleted from this subscribed calendar, I want to create an event on my calendar. I've been able to get this to create the events, but it seems like every time a new event is created, it creates the previously created event too. Which mean I am getting multiple booking in my outlook calendar for the same event.
 
I feel like a condition needs to be added that checks the subject, start and end times and if they match, it shouldn't do anything. If it doesn't match. It should create a new one, but also, if there's a partial match on the day, it should update the existing booking?
 
Can I ask for peoples thoughts on how I should be approaching this please? I'm at the beginners stage of my power automate journey, so any help would be greatly appreciated.
 
Thanks,
Ash

    Do you get ID when you get the events from the subscribed calendar? 
     

    Here’s the process I follow:

    1. Create a mapping table that has a column for ids from subscribed calendar, and ids from your calendar (added after creation)
    2. Set up a flow that runs on a recurring schedule.

    3. Retrieve all events from the subscribed calendar.

    4. Filter the events to include only those created or modified since the last flow run (with a 1–2 minute overlap for safety).

    5. For each event:

      • If the event ID already exists in the mapping table, update the corresponding record.

      • If it doesn’t exist, create event on calendar a new mapping entry with id from subscribed calendar and id from event created
