Quick Integration Guide

Get Your API Key

Create a developer account and generate your API key from the dashboard. Keep your key secure and do not expose it in client-side applications.

API_KEY = “your_api_key_here”

Upload a Document

Upload a PDF document to the signing platform.

import requests

url = “https://api.arventotechnologies.com/v1/documents”

headers = {“Authorization”: f”Bearer {API_KEY}”}

files = {“file”: open(“document.pdf”, “rb”)}

response = requests.post(url, headers=headers, files=files)

Create Signature Request

Send the document to the signer with OTP verification enabled.

data = {
  “document_id”: “doc_123”,
  “signer”: {
      “name”: “Customer Name”,
      “email”: “customer@email.com”,
      “mobile”: “9999999999”
  }
}

response = requests.post(
  “https://api.arventotechnologies.com/v1/signature-request”,
  headers=headers,
  json=data
)
                        

Handle Webhooks

Receive notifications when documents are signed or completed.

@app.route(‘/webhook’, methods=[‘POST’])
def handle_webhook():
    event = request.json

    if event[‘type’] == ‘document.signed’:
        download_signed_document(event[‘document_id’])
