Create cloud function

collections

- contacts:
    - name
    - total_amount
- transactions:
    - contact_id
    - transaction_type
    - date
    - amount

Q: When I create new transaction, I need to update total_amount in contact collection with logic depend on transaction_type. Manually, I work 👍 but I know that cloud function can make it easy and powerful💪. Problem, I'm zero acknowledge in functions implementation 😪 and he doesn't have serious video on YouTube about that ...

Yes same issue here ...

What?

I need an example of how to use function

Like solution for this. After that, I'll be able to understand function implementation

In your case you might want to trigger an execution via event. The data that triggered the event would be in the event data variable.

Where else are you stuck?

I will create an exemple and share it here to analyze

I highly recommend starting your Appwrite function and playing around with it to really learn how it works
