Product catalog template
Create a product catalog REST API
Model products, prices, stock, categories, and availability, then expose them through a clean REST API built visually in NexApi.
What this workflow solves
Go from idea to a stable HTTP contract without building every backend layer first.
Product catalogs are a strong fit for a resource-oriented API: clients need lists, detail pages, filters, and stable fields while the underlying data can evolve. NexApi lets you configure that contract visually and keep requests observable.
Expose products through list and detail routes.
Model fields such as SKU, price, category, and stock.
Add query behavior for catalog browsing.
Connect a storefront, mobile app, or internal inventory UI.
How it works
A short path from data model to usable endpoint.
Model products
Create the product fields your consumers need and keep internal-only fields out of the public response.
Create catalog endpoints
Add list, detail, and write routes according to the responsibilities of the consuming app.
Shape responses
Return a stable JSON representation even when the underlying source contains extra fields.
Operate the API
Use keys, limits, logs, analytics, webhooks, and OpenAPI as the catalog grows.
GET /r/store/products/p_104{
"id": "p_104",
"sku": "HD-104",
"name": "Core Hoodie",
"price": 64.95,
"inStock": true
}Product detail endpoint
A storefront receives only the fields it needs while the source data can remain richer.
Built into NexApi
The API operations layer is already there.
Start small, then add the controls normally scattered across backend code, gateway config, webhook workers, and observability tools.
Visual endpoint builder
Configure methods, paths, request schemas, and response mappings from one interface.
API keys and access
Add API-key based access rules and keep public endpoints under control.
Rate limits and caching
Apply endpoint-level runtime controls without rebuilding the surrounding backend.
Webhooks and connectors
Connect REST APIs with Google Sheets, Slack, Discord, webhooks, Postgres, MySQL, and external REST APIs.
OpenAPI output
Keep the API contract consumable by documentation and developer tooling.
Logs and analytics
Inspect requests and usage from the same dashboard used to configure the API.
Good fit for
Teams that want to ship the API contract first.
Frequently asked
Can I connect an existing product database?
NexApi includes Postgres and MySQL connectors, which can be useful when the catalog already lives in a database.
Can I hide internal fields?
Response mapping lets you shape the public contract instead of returning every field from the source.
Can I document the catalog API?
OpenAPI output is available for configured APIs, making the contract easier to share with developers and tooling.
