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​

  1. Create the template.
  2. Run the saved fixture.
  3. 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.
