When working with HTTP APIs, understanding how to query data is essential. Below are key concepts and practices for effective data retrieval:

1. HTTP Methods for Data Querying

  • GET: Retrieve data from the server (✅ Safe method)
    GET_Request
  • POST: Submit data to the server (❌ Not suitable for queries)
  • PUT: Update data on the server (❌ Not for querying)
  • DELETE: Remove data from the server (❌ Not for querying)

2. Query Parameters

  • Append key-value pairs to the URL path (e.g., /en/guides/query-data?filter=active)
  • Use & to separate multiple parameters (e.g., /en/guides/query-data?sort=date&limit=10)
    Query_Parameters

3. Best Practices

  • Always validate input parameters (🛡️ Security)
  • Limit data returned to avoid unnecessary load (📦 Efficiency)
  • Use pagination for large datasets (📄 Navigation)
  • Check the API Response Structure for proper data handling

4. Example Request

GET /en/guides/query-data?query=example HTTP/1.1
Host: yourdomain.com
Accept: application/json
