Request Reliability

Source file: examples/request_reliability.hen

What It Demonstrates

• preamble reliability defaults
• request-level overrides
• dependency-driven follow-up requests
• poll_until with a fixed retry interval

Key Pattern

timeout = 30s
poll_every = 1s

---

Create export

POST {{ API_ORIGIN }}/echo

~~~json
{
  "jobId": "export-orders-csv",
  "format": "csv",
  "resource": "orders"
}
~~~

^ & status == 200
& body.jobId -> $JOB_ID

---

Wait for export

> requires: Create export
POST {{ API_ORIGIN }}/echo
timeout = 5s
poll_until = 2m
poll_every = 2s

Run It

hen verify ./examples/request_reliability.hen
hen run ./examples/request_reliability.hen all --non-interactive

What To Notice

• The second request inherits the preamble defaults, then overrides only the values it needs.
• Polling retries after assertion failures or per-attempt timeouts.
• The captured JOB_ID keeps the second request tied to the first request’s output.
• The live example uses an echo-backed mock job so the flow stays runnable in CI and local docs.
