Flaky vendor — retry then catch

A vendor call inside a Try block: it retries once, and when it still fails the ERROR lane takes over with the details — the run survives. This demo's vendor always fails so you can see the catch path.

What’s inside

5 nodes — every type links to its full reference page.

Step	Node	Type
Shipment	Inject	`input.inject`
Try vendor	Try	`error-handling.try`
Vendor tracking call	JavaScript	`utility.javascript`
Ops alert	Console	`utility.console`
Tracking updated	Console	`utility.console`

Import it

Studio → Import — paste the JSON below (or the URL /docs/templates/flaky-vendor-retry-then-catch.json).

Or ask the AI Copilot with the JSON pasted after the phrase:

import this workflow json into a new workflow named "Flaky vendor — retry then catch"

Any credentials the nodes need are ${credential.…} references — add them once in Admin → Credentials and the template picks them up. Nothing secret ships in a template.
