Integration Patterns
05 · Watch: a callout built end to end
Twenty minutes from a blank class to a tested, mocked, named-credential callout — narrated, mistakes left in.
Integration Patterns
04 · Middleware or point-to-point?
Two systems talking directly is simple right up until it is three systems, then five. Where the line actually sits.
Integration Patterns
03 · Batch sync without tears
Nightly loads still run the world. Upsert on external IDs, order parents before children, and make reruns safe.
Integration Patterns
02 · Fire-and-forget with platform events
When the caller does not need an answer, publish an event and move on — decoupling, replay, and the delivery guarantees you actually get.

01 · Request-reply with named credentials
The synchronous callout, done properly: named credentials for auth, a timeout you chose on purpose, and a mock for the test.

Your after-update updates the record, which fires your after-update. Breaking the loop without breaking legitimate re-entry.

Data Model Basics
05 · Junction objects in practice
Many-to-many done properly: two master-details, sharing inherited from both sides, and a real example built end to end.
Data Model Basics
04 · Schema Builder, the honest map
The one Setup tool that shows your data model as it is, not as the ERD on the wiki claims it is.
