To install the signplus-python package using pip, you can use the following command:

After installing the package, you can call your first SDK method:

from signplus import Signplus, Environment
from signplus.models import CreateEnvelopeRequest

sdk = Signplus(
    access_token="YOUR_ACCESS_TOKEN",
    timeout=10000
)

request_body = CreateEnvelopeRequest(
    name="name",
    flow_type="REQUEST_SIGNATURE",
    legality_level="SES",
    expires_at=1822567389015,
    comment="comment",
    sandbox=True
)

result = sdk.signplus.create_envelope(request_body=request_body)

print(result)
