Invoking application API on file change in Storage bucket

Question

I have a requirement where-in.

1. A file will be uploaded to Google storage bucket.
2. On file change we have to invoke an API with the file name which got uploaded.

How this can be achieved.? I went through Google pub/sub or cloud functions didn't get much.

Answer 1

You should add the Object Finalize event. This event triggers when a new object is created in the bucket (or an existing object is overwritten, and a new generation of that object is created).
