const data = await response.json();

Python:

import requests

response = requests.get(
    'https://api.example.com/v1/resource/123',
    headers={'Authorization': 'Bearer YOUR_API_KEY'}
)
data = response.json()

Go:

req, _ := http.NewRequest("GET", "https://api.example.com/v1/resource/123", nil)
req.Header.Set("Authorization", "Bearer YOUR_API_KEY")
resp, _ := client.Do(req)
