REST APIs / JSON / RapidAPI
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'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.
