Ask HN: How do you handle API integrations with 3d parties?

At our company, we're planning on integrating with third-party apps our clients use to ingest data directly into those apps, instead of our clients having to manually synchronize data. One approach we came up with was to decouple integrations logic from our main app, i.e. having the main app talk to bunch for microservices(1 per integration). Anyone had a similar experience?
