Bandwidth maintains comprehensive documentation, SDKs for popular programming languages, and active community support. The API is built on REST principles, returning JSON responses with standard HTTP status codes, making it straightforward to integrate into existing workflows.

Authentication

This API uses API Key + Secret authentication. Include both your API key and API secret in the request for authentication.

Always store your credentials securely using environment variables or a secrets manager. Never commit API keys to version control or expose them in client-side code.

Code Samples

Python

import requests
import os

API_KEY = os.environ.get("API_KEY", "YOUR_API_KEY")
BASE_URL = "https://api.bandwidth.com"

headers = {
    "Authorization": f"Bearer {API_KEY}",
    "Content-Type": "application/json"
}

response = requests.get(f"{BASE_URL}/v1/resources", headers=headers)
print(response.status_code)
print(response.json())

JavaScript

const API_KEY = process.env.API_KEY || 'YOUR_API_KEY';
const BASE_URL = 'https://api.bandwidth.com';

const response = await fetch(`${BASE_URL}/v1/resources`, {
  headers: {
    'Authorization': `Bearer ${API_KEY}`,
    'Content-Type': 'application/json'
  }
});
const data = await response.json();
console.log(data);

cURL

curl -H "Authorization: Bearer $API_KEY" \
     -H "Content-Type: application/json" \
     https://api.bandwidth.com/v1/resources

Go

package main

import (
    "net/http"
    "fmt"
    "io"
    "os"
)

func main() {
    apiKey := os.Getenv("API_KEY")
    if apiKey == "" {
        apiKey = "YOUR_API_KEY"
    }
    req, _ := http.NewRequest("GET", "https://api.bandwidth.com/v1/resources", nil)
    req.Header.Set("Authorization", "Bearer " + apiKey)
    req.Header.Set("Content-Type", "application/json")
    resp, _ := http.DefaultClient.Do(req)
    defer resp.Body.Close()
    body, _ := io.ReadAll(resp.Body)
    fmt.Println(string(body))
}
