Hellosign Python SDK

A Python wrapper for the HelloSign API

Installation

Install using easy_install:

easy_install hellosign-python-sdk

Install using pip:

pip install hellosign-python-sdk

Install from code:

git clone https://github.com/HelloSign/hellosign-python-sdk.git
cd hellosign-python-sdk
python setup.py install

Configuration

In your application, import HSClient:

from hellosign_sdk import HSClient

Then create a HSClient object and pass authentication information to initialize it:

# Initialize HSClient using email and password
client = HSClient(email_address="api_user@example.com", password="your_password")

# Initialize HSClient using api key
client = HSClient(api_key="your_api_key")

# Initialize HSClient using api token
client = HSClient(access_token="your_api_access_token")

Note: In case you initialize the HSClient with all the above credentials, the priority order is as follow: access_token, api_key, then email and password.

Usage

For more information about the wrapper, its methods and parameters visit our detailed API documentation on readthedocs.

Account

Get current account information

account = client.get_account_info()

The account information is also stored in client.account. For example, to print the email_address of your account:

print client.account.email_address

Update your account information

client.account.callback_url = "https://www.example.com/callback"
client.update_account_info()

Create a new HelloSign account

new_account = client.create_account("new_user@example.com")

Signature Request

Get a Signature Request

signature_request = client.get_signature_request("fa5c8a0b0f492d768749333ad6fcc214c111e967")
print signature_request.requester_email_address
print signature_request.signature_request_id

Get a list of your Signature Requests

signature_request_list = client.get_signature_request_list(page=1)

# Print out the name of the signers in every signature request
for signature_request in signature_request_list:
    print signature_request.signatures[0].signer_name

Send a Signature Request

                                title="NDA with Acme Co.",

                                message="Please sign this NDA and then we can discuss more. Let me know if you have any questions.",

                                form_fields_per_document=None)

# Retrieve the signature url to pass to the embedded iFrame
for signature in signature_request.signatures:
    embedded_obj = client.get_embedded_object(signature.signature_id)
    sign_url = embedded_obj.sign_url

More information about the asscociated front-end code can be found here

Embedded requesting

# Create a draft and retrieve the claim url
draft = client.create_embedded_unclaimed_draft(
                    test_mode=True,
                    client_id="YOUR CLIENT ID",
                    requester_email_address="requester@example.com",
                    files=["path/to/NDA.pdf"],
                    draft_type="signature_request",
                    subject="The NDA we talked about",
                    message="Please sign this NDA and then we can discuss more. Let me know if you have any questions.",
                    is_for_embedded_signing=False)
claim_url = draft.claim_url

More information about the associated front-end code can be found here

Once the user edits the draft in the embedded iFrame and sends the signature request your app callback will receive a signature_request_sent event containing a SignatureRequest object. If we had used is_for_embedded_signing=True, we would want to get the signature ids out of the SignatureRequest from that event and fetch the signature urls at this point. In your event callback handler, you will need to do something like this:

client = HSClient(api_key='your_api_key')
event_data = json.loads(request.POST.get('json'))
if event_data['event']['event_type'] == 'signature_request_sent':
    sig_req = event_data['signature_request']
    for sig in sig_req['signature_request']['signatures']:
        embedded_obj = client.get_embedded_object(sig['signature_id'])
        sign_url = embedded_obj.sign_url
        # Save sign_url somewhere

Tests

You can run the test suite by executing the following commands after you cloned the repo: Note that it requires to have a HelloSign account, with at least one template and one api app.

WARNING: We advise against running the tests against your personal account as they perform destructive actions.

cd hellosign_sdk
cp tests/test_helper.sample.py tests/test_helper.py
HELLOSIGN_API_KEY='YOUR API KEY'
HELLOSIGN_API_CLIENT_ID='YOUR APP CLIENT ID'
HELLOSIGN_API_CLIENT_SECRET='YOUR APP CLIENT SECRET'
nosetests --with-coverage --cover-package=hellosign_sdk --include=hellosign_sdk/tests/unit_tests/* --include=hellosign_sdk/tests/functional_tests/*

Additional notes

Local callbacks

We do not allow app callbacks (event or OAuth) to be set to localhost. However it is still possible to test callbacks against a local server. Tunneling services such as ngrok can help you set this up.
