How do I connect two systems that don't integrate?

If both have an API, they can be connected — through a middleware platform for standard cases, or with custom code when the logic is specific. If one has no API, the fallbacks are scheduled file exports, email parsing, or database access, in that order of preference.

Decide what the source of truth is before wiring anything. Two systems syncing both directions without a designated winner produce conflicts that are far harder to debug than the original manual step.

Also decide what happens when the sync fails, because it will. Silent failure is worse than no automation, since people stop checking.
