ci: notify the Postman collection pipeline when a spec release lands

[cb-logesh]

What

Adds .github/workflows/notify-postman.yml — the first workflow in this repository. On any push to main touching spec/**, it sends a repository_dispatch (openapi-spec-published) to chargebee/cb-openapi-generator, which regenerates the public Chargebee Postman collections from spec/ and opens a pull request carrying the diff.

Why here

spec/ is updated by cb-sdk-gen's public-sdk-release → specs-release.yml, which opens a PR against this repository. Merging that PR is the moment the specification becomes public, because this repository's main is what downstream consumers read. That makes this repo — not the SDK release workflow — the right place to announce it.

The Postman pipeline deliberately does not trigger on public-sdk-release completing: that workflow proposes the change rather than publishing it, and builds SDKs from chargebee_sdk_spec.json on CloudFront, which is a different artefact from the spec/ files the collections are generated from.

Why it is safe

It is a latency optimisation, not a dependency:

• The consumer already polls hourly and keys on this repository's commit SHA. If the dispatch never fires, the collections still follow — just up to an hour later instead of within minutes.
• The step fails soft. A missing token logs a notice and exits 0; a non-204 response logs a warning. A spec release must not report as broken because a downstream notification could not be sent.
• permissions: contents: read, and the workflow touches nothing in this repository.
• Nothing auto-merges downstream. The dispatch opens a pull request that a human reviews.

One prerequisite before this does anything

A repository secret POSTMAN_REGEN_DISPATCH_TOKEN — a fine-grained token with Contents: read and write on chargebee/cb-openapi-generator and no other permission (that is what the repository_dispatch API requires). Merging without it is harmless: the step logs a notice and exits 0.

Testing it

After the secret exists, run the workflow manually (workflow_dispatch) and check that postman-regenerate starts in cb-openapi-generator. A run for a SHA already generated from exits in seconds, so a manual trigger is cheap and repeatable.

cc @Alish — this implements the pinning you suggested, at the merge event rather than at the SDK release run.

Adds a GitHub Actions workflow that notifies chargebee/cb-openapi-generator after spec/** changes reach main. The workflow also supports manual runs, skips safely without POSTMAN_REGEN_DISPATCH_TOKEN, and treats dispatch failures as warnings.

Walkthrough

The pull request adds a GitHub Actions workflow that notifies the Postman generator when spec/** changes on main or when manually dispatched. It passes the current commit SHA and reports unavailable tokens or non-204 responses without blocking the workflow.

Changes

Postman generator notification

Layer / File(s)	Summary
Conditional generator dispatch .github/workflows/notify-postman.yml	The workflow triggers on specification changes and manual dispatches. It sends a repository_dispatch event with the current commit SHA when the dispatch token is available. It treats missing tokens and non-204 responses as non-blocking conditions.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to df481

The workflow adds a best-effort downstream notification; without explicit request and job timeouts, a stalled call could consume runner time, but this is a bounded non-blocking concern and the PR is merge-ready with follow-up to add timeouts.

Add job and HTTP request timeouts.

curl has no connection or total timeout. A stalled request can consume runner minutes until the job limit. Set timeout-minutes on the job. Set --connect-timeout and --max-time on curl.

Proposed change

   notify:
     runs-on: ubuntu-latest
+    timeout-minutes: 5
     steps:
...
-          status=$(curl -sS -o /tmp/dispatch.out -w '%{http_code}' \
+          status=$(curl -sS --connect-timeout 10 --max-time 30 \
+            -o /tmp/dispatch.out -w '%{http_code}' \

Keep curl transport errors on the soft-failure path

When GitHub's API cannot be reached because of a DNS, connection, or TLS error, curl exits nonzero (curl --manual documents failures such as exit 6 for DNS and 7 for connection errors). GitHub Actions runs this implicit Bash step with -e, and the assignment inherits curl's exit status, so execution stops here instead of reaching the warning branch. This makes the workflow fail precisely for a class of downstream notification failures that the workflow says must fail soft; capture/neutralize the curl exit status before inspecting the result.
