The Flowroute Python library v3 provides methods for interacting with [Numbers v2](https://developer.flowroute.com/api/numbers/v2.0/) and [Messages v2.1](https://developer.flowroute.com/api/messages/v2.1/) of the [Flowroute](https://www.flowroute.com) API.
2. Switch to the newly-created `flowroute-sdk-v3-python` directory. This version of the library comes with a requirements file listing the required Python libraries. See [Installing Packages](https://packaging.python.org/tutorials/installing-packages/) to learn more about different ways to install Python packages.
`pip` is already installed if you're using `Python 2 >=2.7.9` or `Python 3 >=3.4`. This version of the library has been tested with both `Python 2.7.9` and `Python 3.6.4` for Mac OS X. To see which version of `pip` is installed on your machine, run the following:
In Flowroute's approach to building the Python library 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 messaging, number management, and route management within the Python library.
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. All request parameters are optional. If you don't specify a limit, results are limited to the first 10 items.
* [list\_available\_exchange\_codes()](#list_available_exchange_codes) \- Returns a list of all Central Office (exchange) codes containing purchasable phone numbers. All request parameters are optional.
* [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(purchasable\_number)](#purchase_a_phone_numbernumber_id) \- Lets you purchase a phone number from available Flowroute inventory.
* [list\_phone\_number\_details(number\_id)](#list_phone_number_detailsnumber_id) \- Returns details on a specific phone number associated with your account, including primary voice route, and failover voice route if previously configured.
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) \- Creates a new inbound route which can then be assigned as either a primary or a failover voice route for a phone number on your account.
* [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 phone numbers on your account.
* [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 library v3 comes with a **demo.py** file that you can edit and run as an example.
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 your Flowroute credentials 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).
The following section will demonstrate the capabilities of Numbers v2 and Messages v2.1 that are wrapped in our Python library. Note that the example responses have been formatted using Mac's `pbpaste` and `jq`. To learn more, see [Quickly Tidy Up JSON from the Command Line](http://onebigfunction.com/vim/2015/02/02/quickly-tidying-up-json-from-the-command-line-and-vim/).
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/).
The method accepts `limit`, `offset`, `max_setup_cost`, and `areacode` as parameters which you can learn more about in the [API reference](https://developer.flowroute.com/api/numbers/v2.0/list-available-exchanges/).
The method accepts `starts_with`, `contains`, `ends_with`, `limit`, `offset`, `rate_center`, and `state` as parameters which you can learn more about in the [API reference](https://developer.flowroute.com/api/numbers/v2.0/search-for-purchasable-phone-numbers/).
The method is used to purchase a telephone number from Flowroute's inventory and accepts the phone number `id` as a parameter which you can learn more about in the [API reference](https://developer.flowroute.com/api/numbers/v2.0/purchase-a-phone-number/). In the following example, we assign the `id` of the first phone number in the resulting JSON array as the phone number to be purchased. Note that this function call is currently commented out. Uncomment to test the `purchase_a_phone_number` method.
The method accepts `starts_with`, `ends_with`, `contains`, `limit`, and `offset` as parameters which you can learn more about in the [API reference](https://developer.flowroute.com/api/numbers/v2.0/list-account-phone-numbers/).
The method accepts the `number_id` as a parameter which you can learn more about in the [API reference](https://developer.flowroute.com/api/numbers/v2.0/list-phone-number-details/). In the following example, we request the details of the first phone number returned after calling the `list_account_phone_numbers` method.
The method accepts the route object in JSON format as a parameter which you can learn more about in the [API reference](https://developer.flowroute.com/api/numbers/v2.0/create-an-inbound-route/). In the following example, we define a function to generate a six-character random string for our subdomain which we later concatenate with our example domain and assign as our `host` value. We use the same function to generate a unique `alias`.
The method accepts `limit` and `offset` as parameters which you can learn more about in the [API reference](https://developer.flowroute.com/api/numbers/v2.0/list-inbound-routes/).
The method accepts a phone number `id` and a route record object in JSON format as parameters which you can learn more about in the [API reference](https://developer.flowroute.com/api/numbers/v2.0/update-number-primary-voice-route/). In the following example, we extract the second route in our `list_inbound_routes` search result and assign it as the primary voice route for our previously declared `number_id`.
On success, the HTTP status code in the response header is `204 No Content` which means that the server successfully processed the request and is not returning any content.
The method accepts a phone number `id` and a route record object in JSON format as parameters which you can learn more about in the [API reference](https://developer.flowroute.com/api/numbers/v2.0/update-number-failover-voice-route/). In the following example, we extract the third and last route in our `list_inbound_routes` search result and assign it as the failover voice route for our previously declared `number_id`.
On success, the HTTP status code in the response header is `204 No Content` which means that the server successfully processed the request and is not returning any content.
The Flowroute Python library v3 allows you to make HTTP requests to the `messages` resource of Flowroute API v2.1: `https://api.flowroute.com/v2.1/messages`
The method accepts a message object in JSON format as a parameter which you can learn more about in the API References for [MMS](https://developer.flowroute.com/api/messages/v2.1/send-an-mms/) and [SMS](https://developer.flowroute.com/api/messages/v2.1/send-an-sms/). In the following example, we are sending an MMS with a `gif` attachment from the previously declared `number_id` to your mobile number.
The method accepts `start_date`, `end_date`, `limit`, and `offset` as parameters which you can learn more about in the [API Reference](https://developer.flowroute.com/api/messages/v2.1/look-up-set-of-messages/).
##### Example Request
```python
print ("---Look Up A Set Of Messages")
start_date = "2017-12-01"
end_date = "2018-01-08"
limit = 2
result = messages_controller.look_up_a_set_of_messages(start_date, end_date, limit)
pprint.pprint(result)
```
##### Example Response
On success, the HTTP status code in the response header is `200 OK` and the response body contains an array of message objects in JSON format.
