When consuming APIs, you need to send requests and handle responses: including errors, status codes, and deserialization.
🚀 Sending Requests

var response = await client.GetAsync("https://api.example.com/users/1");

📦 Handling Responses
- Always check the status code:

| if (response.IsSuccessStatusCode)
{
var content = await response.Content.ReadAsStringAsync();
// Deserialize if needed
}
else
{
Console.WriteLine($"Error: {response.StatusCode}");
}

- Handle exceptions with try/catch.

var postResponse = await client.PostAsync("https://api.example.com/users", payload);

⚠️ Tips
- Set necessary headers (like
Authorization or User-Agent).
- Use async/await for non-blocking I/O.
