I want to learn how to build integrations, such as how to connect two systems made by different companies that have different structures.

For example: To cut down on redundant data entry, I want to build an integration where the data is pushed from one software to another software. The integration would put the data from the source software into the correct fields in the destination software.

How do I go about learning how to build integrations? What classes to even start with?

I appreciate any guidance you can provide.

Edit: Thanks a bunch for the suggestions. I’m checking out those tools suggested in the comments and looking up classes to learn the skills needed.
