I’ve found that the API Pages can handle most of the work. Anything else can be done in the Business Central Web Services.

These are just OData. And really easy to set up via a PTE Extension.

I highly recommend you understand all the API limits and per-tenant limits on your integrations. This has been an issue for me and could easily make or break a process in large user environments.

BCCL is another tool in my back pocket. It’s made by Erik Hougaard you can utilize it to move data in/out of BC in bulk.
