Regaring scheduling an event bridge trigger

Hi All, I am having a requirement, which should to the following things:

1. Call an external cliient api from AWS to fetch a file daily once.

2. While fetching a file, the below are the scenarios:

   -- If fetching of the file from the external api is failed in the first attempt, then check again in a interval of 15 minutes. Do this check like this for every 15 minutes upto 2 hours. If after 2 hours also, the file fetching is failed from the external api, then log the failure.

   -- If fetching of the file is sucussful, then stop calling the external api to fetch the file again, for that      day and push that file to store into s3.
   

The Problem:

As per inital design, I am using an aws event bridge scheduler to schedule for every 15 minutes to trigger the lambda upto 2 hours

This lambda will call the external api and keep the file into s3.

But one, thing which I am finding a bit hard to figure it out is that, in case,

 -- If i  am successful, in retrieving the file from the external api, then how can I ask the aws event      scheduler to stop re-triggering for that day.

  ---  If even after 2 hours, I am not able to fetch the file, then how could eventbridge or the lambda can log (because, 

  ---- 1) event bridge will not know anything about success of failure and it only knows that it. should trigger for every 15 minutes upto 2 hours

        2) lambda is not aware, if the window scheduled for 2 hours is completed)

Is there any better approach if any one can suggest for the above.
