Build a simple mental model before touching controls.
Learn loyalty by proving each step.
Nine plain-language lessons turn platform concepts into Sandbox evidence. Complete practical checklists on this device, then pass a stronger knowledge assessment for a revocable, publicly verifiable credential.
Every lesson ends with observable Sandbox evidence.
Progress and lab checks stay on this device.
A scored assessment creates a public credential record.
From first principles to production control.
Select a track, open a lesson, check each lab step, and mark it complete when you can show the evidence.
- Name the five core objects
- Separate configuration from business facts
- Trace one outcome back to evidence
Start with the business fact
An event says what actually happened: an order completed, a return posted, or a registered behavior occurred. The event should carry your stable source reference so both systems can talk about the same fact.
Let policy decide
A program contains the earn rule, tiers, rewards, limits, pending period, and expiration policy. A campaign may modify an outcome for a bounded audience or time; it does not replace the program.
Keep the evidence
The ledger records balanced movements. The member balance, tier, and webhook outcome are views of recorded decisions, not disconnected totals that people should overwrite.
Trace one purchase on paper
Check a step only after you have done it. These checks stay on this device.
You can explain every displayed point using a source reference and policy.
Show what you understand.
The course and assessment are public and account-free. The credential validates this twelve-question knowledge assessment; practical labs are self-checked, not observed by Loyumi.
