Happy Endpoint APIs

Happy Endpoint provides structured JSON APIs for retail, real estate, travel, grocery, beauty, furniture, and marketplace data. Use these docs to authenticate with RapidAPI, browse endpoint references, and build reliable data workflows for production apps.

Quick start

Send your RapidAPI headers

Every Happy Endpoint API uses the RapidAPI key and host headers. The host value changes per API, but the authentication pattern stays the same across Sephora, Tesco, IKEA, PropertyFinder, Bayut, and Priceline.

curl --request GET \
  --url 'https://YOUR-RAPIDAPI-HOST/path' \
  --header 'X-RapidAPI-Key: YOUR_RAPIDAPI_KEY' \
  --header 'X-RapidAPI-Host: YOUR-RAPIDAPI-HOST'

API catalog

Choose the API that matches your data workflow

Each reference page is generated from its OpenAPI document and includes endpoint paths, parameters, response examples, and request samples. Start with search or listing endpoints when discovering records, then call detail endpoints only when your application needs richer data.

Sephora API

Beauty catalog, search, brand, category, store, and product data.

Open reference

Tesco API

Grocery product search, pricing, catalog, and detail data.

Open reference

IKEA API

Furniture, home goods, product detail, and catalog data.

Open reference

PropertyFinder API

UAE property listings, locations, prices, and market data.

Open reference

Bayut API

UAE real estate search, listing, agency, and price data.

Open reference

Priceline API

Hotel, destination, pricing, and travel discovery data.

How it works

Global guides cover shared integration patterns

Credits, status codes, API keys, timeouts, usage patterns, and best practices apply across the API catalog. Read these pages before building a production integration, especially if you plan to run scheduled imports, price monitoring, property search, or catalog enrichment jobs.

API references stay endpoint-specific

Sephora, Tesco, IKEA, PropertyFinder, Bayut, and Priceline each open their own Scalar reference from a separate OpenAPI JSON file. This keeps endpoint parameters, request examples, and response models focused on the API you are integrating.

Production checklist

Secure credentials

Keep RapidAPI keys in server-side environment variables or secret storage. Never send keys from browser JavaScript, mobile clients, public repositories, screenshots, or client-side logs.

Handle common API failures

Check the HTTP status code before parsing the response. Fix 400-range request errors, alert on authentication failures, slow down after 429 rate limits, and retry timeouts or 500-range errors with capped exponential backoff.

Plan usage before scaling

Cache stable data, deduplicate repeated lookups, and move large jobs into queues. Log endpoint usage and response times so you can explain credit consumption and debug issues without exposing secrets.
