The Flowroute Python API Wrapper v3 provides methods for interacting with **[Numbers v2](#numbers)** and **[Messages v2.1](#messaging)** of the [Flowroute](https://www.flowroute.com) API.
2. Switch to the newly-created `flowroute-numbers-messaging-python` directory. Version 3 of the Flowroute SDK for Python comes with a requirements file listing the required Python libraries. Click [here](https://packaging.python.org/installing/#requirements-files) to learn more about different ways to install Python packages. Depending on your `pip` permissions, you may be required to preface each `pip` command with `sudo`.
In Flowroute's approach to building Python API Wrapper v3, HTTP requests are handled by controllers named after the API resources they represent: **Numbers**, **Routes**, and **Messages**. These controllers contain the methods used to perform number management, route management, and messaging tasks with the Python SDK.
Contains all of the methods necessary to search through Flowroute's phone number inventory, purchase a phone number, and review details of your account phone numbers.
* [list\_available\_area\_codes()](#list_available_area_codes) \- Returns a list of all Numbering Plan Area (NPA) codes containing purchasable phone numbers.
* [list\_available\_exchange\_codes()](#list_available_exchange_codes) \- Returns a list of all Central Office (exchange) codes containing purchasable phone numbers.
* [search\_for\_purchasable\_phone\_numbers()](#search_for_purchasable_phone_numbers) \- Searches for purchasable phone numbers by state or rate center, or by your specified search value.
* [purchase\_a\_phone\_number(number\_id)](#purchase_a_phone_numbernumber_id) \- Lets you purchase a phone number from available Flowroute inventory.
* [list\_account\_phone\_numbers()](#list_account_phone_numbers) \- Returns a list of all phone numbers currently on your Flowroute account. The response includes details such as the phone number's rate center, state, number type, and whether CNAM Lookup is enabled for that number.
* [list\_phone\_number\_details(numberid)](#list_phone_number_detailsnumber_id) \- Lists all of the information associated with any of the phone numbers in your account, including billing method, primary voice route, and failover voice route.
Contains the methods required to create new inbound routes, view all of your account routes, and update primary and failover voice routes for your phone numbers.
* [create\_an\_inbound\_route(route\_body)](#create_an_inbound_routeroute_body) \- Create a new inbound route that can then be assigned as either a primary or failover voice route for a phone number.
* [list\_inbound\_routes()](#list_inbound_routes) \- Returns a list of your inbound routes. From the list, you can then select routes to use as the primary and failover voice routes for your phone number.
* [update\_primary\_voice\_route(number\_id, route\_body)](#update_primary_voice_routenumber_id-route_body) \- Updates the primary voice route for a phone number. You must create the route first via the `create_an_inbound_route(routebody)` method.
* [update\_failover\_voice\_route(number\_id, route\_body)](#update_failover_voice_routenumber_id-route_body) \- Updates the failover voice route for a phone number. You must create the route first via the `create_an_inbound_route(routebody)` method.
* [send\_a\_message(message\_body)](#send_a_messagemessage_body) \- Sends an SMS or MMS from a Flowroute long code or toll-free phone number to another valid phone number.
* [look\_up\_a\_message\_detail\_record()](#look_up_a_message_detail_recordmessage_id) \- Searches for a specific message record ID and returns a Message Detail Record (in MDR2 format).
* [look\_up\_a\_set\_of\_messages()](#look_up_a_set_of_messagesstart_date) \- Retrieves a list of Message Detail Records (MDRs) within a specified date range. Date and time is based on Coordinated Universal Time (UTC).
The following shows an example of a single Python file that imports the Flowroute API client and all the required modules. The Python SDK comes with a **demo.py** file that you can edit and run as an example.
```python
import pprint
import os
import json
from flowroutenumbersandmessaging.flowroutenumbersandmessaging_client import FlowroutenumbersandmessagingClient
```
#### Credentials
In **demo.py**, replace `basic_auth_user_name` with your API Access Key and `basic_auth_password` with your API Secret Key from the [Flowroute Manager](https://manage.flowroute.com/accounts/preferences/api/). Note that in our example, we are accessing them as environment variables. To learn more about setting environment variables, see [How To Read and Set Environmental and Shell Variables](https://www.digitalocean.com/community/tutorials/how-to-read-and-set-environmental-and-shell-variables-on-a-linux-vps).
Flowroute SDK version 3 for Python allows you to make HTTP requests to the `numbers` resource of Flowroute API v2: `https://api.flowroute.com/v2/numbers`
The method accepts `limit`, `offset`, and `max_setup_cost` as parameters which you can learn more about in the [API reference](https://developer.flowroute.com/api/numbers/v2.0/list-available-area-codes/).
