Installation

To install the Python client library using pip:

pip install nexmo

To upgrade your installed client library using pip:

pip install nexmo --upgrade

Alternatively you can clone the repository:

git clone git@github.com:Nexmo/nexmo-python.git

Usage

Begin by importing the nexmo module:

import nexmo

Then construct a client object with your key and secret:

client = nexmo.Client(key=api_key, secret=api_secret)

For production you can specify the NEXMO_API_KEY and NEXMO_API_SECRET environment variables instead of specifying the key and secret explicitly.

For newer endpoints that support JWT authentication such as the Voice API, you can also specify the application_id and private_key arguments:

client = nexmo.Client(application_id=application_id, private_key=private_key)

In order to check signatures for incoming webhook requests, you'll also need to specify the signature_secret argument (or the NEXMO_SIGNATURE_SECRET environment variable).

SMS API

Send a text message

response = client.send_message({'from': 'Python', 'to': 'YOUR-NUMBER', 'text': 'Hello world'})

response = response['messages'][0]

if response['status'] == '0':
  print 'Sent message', response['message-id']

  print 'Remaining balance is', response['remaining-balance']
else:
  print 'Error:', response['error-text']

Docs: https://docs.nexmo.com/messaging/sms-api/api-reference#request

Tell Nexmo the SMS was received

The following submits a successful conversion to Nexmo with the current timestamp. This feature must be enabled on your account first.

response = client.submit_sms_conversion(message_id)

Voice API

Make a call

response = client.create_call({
  'to': [{'type': 'phone', 'number': '14843331234'}],
  'from': {'type': 'phone', 'number': '14843335555'},
  'answer_url': ['https://example.com/answer']
})

Docs: https://docs.nexmo.com/voice/voice-api/api-reference#call_create

Retrieve a list of calls

response = client.get_calls()

Docs: https://docs.nexmo.com/voice/voice-api/api-reference#call_retrieve

Retrieve a single call

response = client.get_call(uuid)

Docs: https://docs.nexmo.com/voice/voice-api/api-reference#call_retrieve_single

Update a call

response = client.update_call(uuid, action='hangup')

Docs: https://docs.nexmo.com/voice/voice-api/api-reference#call_modify_single

Stream audio to a call

stream_url = 'https://nexmo-community.github.io/ncco-examples/assets/voice_api_audio_streaming.mp3'

response = client.send_audio(uuid, stream_url=stream_url)

Docs: https://docs.nexmo.com/voice/voice-api/api-reference#stream_put

Stop streaming audio to a call

response = client.stop_audio(uuid)

Docs: https://docs.nexmo.com/voice/voice-api/api-reference#stream_delete

Send a synthesized speech message to a call

response = client.send_speech(uuid, text='Hello')

Docs: https://docs.nexmo.com/voice/voice-api/api-reference#talk_put

Stop sending a synthesized speech message to a call

response = client.stop_speech(uuid)

Docs: https://docs.nexmo.com/voice/voice-api/api-reference#talk_delete

Send DTMF tones to a call

response = client.send_dtmf(uuid, digits='1234')

Docs: https://docs.nexmo.com/voice/voice-api/api-reference#dtmf_put

Get recording

response = client.get_recording(RECORDING_URL)

Verify API

Start a verification

response = client.start_verification(number='441632960960', brand='MyApp')

if response['status'] == '0':
  print 'Started verification request_id=' + response['request_id']
else:
  print 'Error:', response['error_text']

Docs: https://docs.nexmo.com/verify/api-reference/api-reference#vrequest

The response contains a verification request id which you will need to store temporarily (in the session, database, url etc).

Check a verification

response = client.check_verification('00e6c3377e5348cdaf567e1417c707a5', code='1234')

if response['status'] == '0':
  print 'Verification complete, event_id=' + response['event_id']
else:
  print 'Error:', response['error_text']

Docs: https://docs.nexmo.com/verify/api-reference/api-reference#check

The verification request id comes from the call to the start_verification method. The PIN code is entered into your application by the user.

Cancel a verification

client.cancel_verification('00e6c3377e5348cdaf567e1417c707a5')

Docs: https://docs.nexmo.com/verify/api-reference/api-reference#control

Trigger next verification step

client.trigger_next_verification_event('00e6c3377e5348cdaf567e1417c707a5')

Docs: https://docs.nexmo.com/verify/api-reference/api-reference#control

Number Insight API

Basic Number Insight

client.get_basic_number_insight(number='447700900000')

Docs: https://docs.nexmo.com/number-insight/basic

Standard Number Insight

client.get_standard_number_insight(number='447700900000')

Docs: https://docs.nexmo.com/number-insight/standard

Advanced Number Insight

client.get_advanced_number_insight(number='447700900000')

Docs: https://docs.nexmo.com/number-insight/advanced

Managing Secrets

An API is provided to allow you to rotate your API secrets. You can create a new secret (up to a maximum of two secrets) and delete the existing one once all applications have been updated.

List Secrets

secrets = client.list_secrets(API_KEY)

Create A New Secret

Create a new secret (the created dates will help you know which is which):

client.create_secret(API_KEY, 'awes0meNewSekret!!;');

Delete A Secret

Delete the old secret (any application still using these credentials will stop working):

client.delete_secret(API_KEY, 'my-secret-id')

Application API

Create an application

response = client.create_application(name='Example App', type='voice', answer_url=answer_url, event_url=event_url)

Docs: https://docs.nexmo.com/tools/application-api/api-reference#create

Retrieve a list of applications

response = client.get_applications()

Docs: https://docs.nexmo.com/tools/application-api/api-reference#list

Retrieve a single application

response = client.get_application(uuid)

Docs: https://docs.nexmo.com/tools/application-api/api-reference#retrieve

Update an application

response = client.update_application(uuid, answer_method='POST')

Docs: https://docs.nexmo.com/tools/application-api/api-reference#update

Delete an application

response = client.delete_application(uuid)

Docs: https://docs.nexmo.com/tools/application-api/api-reference#delete

Validate webhook signatures

client = nexmo.Client(signature_secret='secret')

if client.check_signature(request.query):
  # valid signature
else:
  # invalid signature

Docs: https://docs.nexmo.com/messaging/signing-messages

Note: you'll need to contact support@nexmo.com to enable message signing on your account before you can validate webhook signatures.

JWT parameters

By default the library generates short lived tokens for JWT authentication.

Use the auth method to specify parameters for a longer life token or to specify a different token identifier:

client.auth(nbf=nbf, exp=exp, jti=jti)
