How to write a backend service that runs on a timer?

I'm looking to create a backend application that every morning calls an external API and retrieves certain information, and then saves it to my database. I have subscriptions with both DigitalOcean and AWS so I could use either to host. I am very new to web development/javascript but have years of experience in object oriented languages and can pick it up quickly, I'm just not sure where to start for this. Thanks

Very straightforward and easy step based on AWS:

1-Create Lambda function for calling your API and retrive data and save to database.At the moment you can create Lambda function with Node.js (JavaScript), Python, and Java (Java 8 compatible).

2-Create a trigger in trigger tab for your lambda function and select CloudWatch Events for the source with one-day duration.

3-Enjoy your serverless function.
