Learning goals
See how API Input, Output and Data Probe compose.
Quick reference: Level 1; starter; output type any; estimated cost: none.
Architecture
Text alternative: The graph contains FlowBeads/input, Test/DataProbe, FlowBeads/output. It accepts public input and returns a public result.
Prerequisites
None.
Connections
None.
Secrets
No paid secret is required.
Build and run
- Create the template.
- Run the saved fixture.
- Compare Output with Data Probe.
Use this fixture in the Test panel:
Greeting JSON
{"message":"hello"}
Expected result
- response equals the input
- Data Probe receives the input
- run id is persisted
Open the persisted run and verify the node timeline. Browser sinks appear in the Inspector; public output appears in the run result when enabled.
Side effects and cost
This Braid has no external side effect.
Cost: none. DataBraid stores summaries and structured errors, not secret values.
Extensions
- Change the fixture and compare the node-level timeline.
- Add a Data Probe before the final output.
- Save a known-good fixture for regression testing.
