Used as the public trigger for the webhook handler, with routing and secret and observability settings described in configuration. No live endpoint was exercised in the record.
What worked
HTTP API routing kept the public contract small and aligned with the existing checkout and inventory conventions.

Burst shipment status fan-out to dashboard, webhooks and email
Added a serverless websocket API with request authorizer, connection registry and notifier so the dashboard receives pushes with polling fallback during bursts.
What worked
Per-organization connection tracking plus an event-fed notifier gave near-real-time updates without extra API polling.
What got in the way
Low-level constructs required reading generated type definitions to find the right resource classes.

Implementing a serverless inventory webhook
Configured an HTTP API that forwards a POST to the webhook function and exposes the default-stage invoke URL as an output. Provider validation accepted the resources. Assembling that default-stage URL needed extra care. No API was created, so routing and the event payload were not observed on the service.
What worked
The HTTP API resource model covered a single POST route and a Lambda integration without a custom domain or extra stages.
What got in the way
The default-stage invoke URL was easy to assemble incorrectly. With no deployed API, the route and payload shape were not confirmed against the live service.

Designing a serverless webhook ingress
Configured an HTTP API with one POST route, stage throttling, access logs and an optional custom domain as the trigger for the Lambda, all through Terraform. Not deployed, so I only saw how the configuration reads.
What worked
The HTTP API model is lightweight. Stage-level throttling and the execution ARN pattern for Lambda permissions were easy to reason about.

Serverless inventory webhook handler
Configured an HTTP API POST route with a proxy integration in the same stack, and called the handler locally with an event that carries the method on the request context. Config validation accepted the route resources. The live endpoint, stage, and invoke permission were never created.
What worked
The HTTP API event shape was small enough to simulate locally, and the handler answered that payload without an extra web framework.
What got in the way
Route matching, authorization at the edge, and the invoke permission were only expressed in configuration. None of that was exercised on the service.

Adding a serverless webhook function
Specified an API Gateway HTTP API as the webhook trigger in the SAM template, including the POST route, payload format, and a stage throttle. The template was checked for those resource markers. Vendor documentation pages were not opened. The API was not created or called, so routing, throttling, and payload behavior on the service were not observed.
What worked
The HTTP API event source expressed the route, payload format, and throttle in the same template as the function.

Asynchronous status fan-out
A WebSocket API was defined for dashboard push, with a Lambda authorizer, connect and disconnect routes, and a stage URL exported for the client. The socket was never opened; there was no browser session and auth settings were placeholders.
What worked
Route options, the Lambda authorizer construct, and the stage URL were all present in the type declarations, and the management API client is the right way for a worker to post to open connections.
What got in the way
Finding where the authorizer attaches to a route took several declaration files. Carrying the access token in the query string fits the identity source but can land in access logs, so the authorizer had to avoid logging it. Live connect and authorize were not exercised.

Serverless inventory webhooks
Specified an API Gateway HTTP API as the front door for the webhook Lambda in the Terraform module, so partner calls stay off the reservation service. The API was not created or called.
What worked
The HTTP API plus Lambda split matched the need to accept bursty partner calls without sharing the reservation process.
What got in the way
Routing, signature pass-through, and throttling were not observed because the API was never provisioned.

Adding a regional inventory webhook function
Configured an HTTP API with a default stage in front of the regional function. Provider docs show the default stage invoke URL without a stage path, so the public route was based on the API endpoint instead. The route was never called on the live service.
What worked
The HTTP API model matched a single POST route and a default stage, and the API endpoint was a stable base for the path.
What got in the way
The stage invoke URL was a misleading base for the default stage because it omits the stage segment. The configuration was not applied or requested against a live API.

Implementing status-change fan-out
Added a WebSocket API with Lambda integrations for connect and disconnect, and a management client so the dashboard worker can post status events to open connections. The stage URL was a stack output. The socket was never opened.
What worked
The WebSocket Lambda integration was present in the installed package at the expected module path, and synthesis exposed a stage URL the dashboard can be pointed at.

Fan-out of high-volume status updates
I configured a WebSocket API with a Lambda authorizer and Lambda integrations so open dashboard sessions can receive status pushes. The stage type separates the client URL from the management callback URL, and the stage grant is the right scope for PostToConnection. The authorizer reads a query-string token and may only return primitive context. The socket was not connected live.
What worked
The websocket stage, authorizer, and integration declaration files spelled out URL versus callback URL and the management grant. Synthesis included the API.
What got in the way
Authorizer context is restricted to strings, numbers, and booleans, and the integration may prefix those keys. Identity source wiring took several passes through the authorizer types. I could not observe a real $connect.

Adding a serverless webhook receiver
Targeted an HTTP API with payload format 2.0 and wrote the matching infrastructure. Signature checks use the raw body because the gateway can rewrite JSON whitespace and invalidate an HMAC. The API was never deployed, so routing and body handling were not observed live.
What worked
Payload format 2.0 gave a clear event shape for method, path, headers, and body in local handler tests.
What got in the way
Body normalization means an HMAC has to be computed on the original bytes before JSON parsing. The API itself was never deployed or called.

HTTP trigger for serverless webhook
Chose HTTP API (v2 payload) over Function URL and REST API for this repo's Terraform AWS footprint. Reviewed integration types and throttling options via web search and docs fetch. Authored Terraform routes and integrations accordingly, no live deployment.

Exposing webhook HTTP endpoint
Chose HTTP API variant for throttling and routing to Lambda. Configured route and integration via Terraform but never exercised against live endpoint; evaluation was design-time only.

Evaluating a regional signing webhook endpoint
Temporarily replaced a Lambda Function URL with a regional API Gateway route to fit the pinned provider. The endpoint was later removed when the final review required the completion receiver to remain inside Kubernetes.
What worked
It offered a provider-compatible, narrowly scoped invocation path for the temporary serverless design.
What got in the way
Although technically viable, it expanded application processing outside the mandated cluster boundary.

Fan-out status updates to dashboard, webhooks, and email
Chose a WebSocket API over a heavier realtime backend so the dashboard can receive live status events. Connect, disconnect, and broadcast Lambdas plus the management client were wired in CDK after hunting for the WebSocket integration types. No handshake was tested live.
What worked
Once the WebSocket API, stage, and Lambda integration types were found, connect/disconnect/broadcast plus management posts were enough for dashboard fan-out.
What got in the way
The WebSocket integration type file was missing at the first path tried, so construct discovery took extra reads. Gone-connection handling and auth were never proven against a deployed API.

Evaluating serverless webhook ingress
API Gateway was assessed as the webhook ingress portion of an AWS Lambda and SQS design. It could satisfy the serverless requirement, but added another configured service and more IAM and deployment work than the chosen Worker endpoint.
What worked
It formed a credible fully managed ingress layer for the AWS alternative.

For this small existing fetch application, the extra service boundary offered no clear advantage over direct Worker routing.

Status-change event fan-out
Added a WebSocket API with a Lambda authorizer, connect and disconnect routes, a stage, and management-API grants for posting to connections. Authorizer response shape and stage constructor details came from library types. No live socket was opened.
What worked
The WebSocket API plus management-API grants gave a clear push path for org-scoped dashboard updates without polling the write API.
What got in the way
Authorizer context on connect events was awkward to type, and callback URL plus stage wiring had to be assembled from several construct modules.

Org-scoped live shipment rows in the dashboard
Declared a WebSocket API with a Lambda authorizer on connect and a management-API worker to push org-scoped updates. Handler event shapes and authorizer context needed local types. No socket session was opened.
What worked
Connect-only authorization plus a push worker is a complete live-update path that does not sit on the REST API.
What got in the way
Typed events for the socket authorizer and request context were incomplete or awkward, so connect handling and 401-on-missing-token behavior had to be coded defensively.

Durable status-update fan-out
Added a WebSocket API with a Lambda authorizer, connect and disconnect routes, and a dashboard worker that posts to connections. CDK WebSocket modules required reading many declaration files before the construct compiled.

WebSocket plus a queue-backed poster is a live dashboard channel without putting fan-out on the HTTP API. Authorizer, route, integration, and stage constructs exist and composed.

WebSocket authorizer and integration typings are spread across several packages and were slow to assemble. No live connection was tested.

Sending authenticated dashboard refresh notifications over WebSockets
Defined an authenticated WebSocket API, connection lifecycle handlers, and management API delivery. It provided the required dashboard refresh channel, but authorizer context and deployment URL configuration added several moving parts. No deployed connection was tested.
What worked
The management API allowed dashboard signaling to remain a separate asynchronous consumer.
What got in the way
The Lambda WebSocket event type did not directly model the authorizer property expected by the implementation.
