- Request-reply, done properly Named Credentials, timeouts you chose, and the retry that does not double-charge anyone. 35 min
- Platform Events and the at-least-once contract The publish gotchas, replay ids, and why every subscriber ends up idempotent. 40 min
- Batch — the pattern everyone pretends they have outgrown Bulk API 2.0, and the honest cases where a nightly job beats an event bus. 30 min
- The reconciliation job — trust, but verify The nightly comparator that turns "probably consistent" into "we would know". 35 min
About this course
Every lesson uses the same fictional billing system, connected a different way, so by the end you have seen one problem solved four times and know what each solution costs. The final lesson is the one nobody teaches and every production integration eventually grows: the job that checks the other three did what they claimed.
Watched best in order — each pattern is introduced by the failure of the previous one.
