# Adding Routes with API

When managing servers with hundreds of routes the API can be used to create the routes. Below is an example of a common use case of adding public AWS ranges. The API requires an enterprise subscription and the key can be found in the administrators tab of the web console.

```python
import requests
import time
import uuid
import hmac
import hashlib
import base64
import json
import sys

BASE_URL = 'https://server.domain'
API_TOKEN = 'Hv2FxEMoa3moTVuRahMsMK3VUCwdmjmt'
API_SECRET = 'zihea5hTIpIgxsPFboby4hctopxWQSKd'
SERVER_ID = '57e9e364fd632c233e86f827'
REGIONS = {
    # 'GLOBAL',
    #
    # 'us-east-1',
    # 'us-east-2',
    # 'us-west-1',
    # 'us-west-2',
    # 'us-gov-west-1',
    #
    # 'eu-central-1',
    # 'eu-west-1',
    #
    # 'ap-south-1',
    # 'ap-northeast-1',
    # 'ap-northeast-2',
    # 'ap-southeast-1',
    # 'ap-southeast-2',
    #
    # 'cn-north-1',
    #
    # 'sa-east-1',
    #
    # 'us-gov-west-1',
}

def auth_request(method, path, headers=None, data=None):
    auth_timestamp = str(int(time.time()))
    auth_nonce = uuid.uuid4().hex
    auth_string = '&'.join([API_TOKEN, auth_timestamp, auth_nonce,
        method.upper(), path])
    if sys.version_info[0] < 3:
        auth_signature = base64.b64encode(hmac.new(
            API_SECRET, auth_string, hashlib.sha256).digest())
    else:
        auth_signature = base64.b64encode(hmac.new(
            API_SECRET.encode('utf-8'), auth_string.encode('utf-8'), hashlib.sha256).digest())
    auth_headers = {
        'Auth-Token': API_TOKEN,
        'Auth-Timestamp': auth_timestamp,
        'Auth-Nonce': auth_nonce,
        'Auth-Signature': auth_signature,
    }
    if headers:
        auth_headers.update(headers)
    return getattr(requests, method.lower())(
        BASE_URL + path,
        headers=auth_headers,
        data=data,
    )

response = requests.get('https://ip-ranges.amazonaws.com/ip-ranges.json')
ranges = response.json()
routes = []

for range in ranges['prefixes']:
    if range['region'] not in REGIONS:
        continue

    routes.append({
        'network': range['ip_prefix'],
        'nat': True,
    })

response = auth_request(
    'POST',
    '/server/%s/routes' % SERVER_ID,
    headers={
        'Content-Type': 'application/json',
    },
    data=json.dumps(routes),
)
assert(response.status_code == 200)

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.pritunl.com/kb/vpn/servers/adding-routes-with-api.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
