What are Scrini AI Webhooks and Why Use Them?

Scrini AI Webhooks are HTTP callbacks that notify your external systems about specific events occurring within the Scrini AI platform in real-time. This mechanism is defined as a powerful 'push' notification system, ensuring immediate data synchronization and triggering of downstream processes.

The key benefits of using webhooks for technical integration include:

• Real-time Data Flow: Instantly react to events like `candidate.created` or `stage.changed`.
• Reduced Polling Overhead: Eliminate the need for constant API calls to check for updates, saving resources.
• Event-Driven Architectures: Build highly responsive and scalable systems that react autonomously.
• Enhanced Automation: Automate workflows that span multiple applications without manual intervention.

According to recent industry research by Gartner, over 70% of organizations plan to increase their investment in API-led integration strategies by 2027, highlighting the growing importance of smooth data exchange.

Prerequisites: Getting Started with Scrini AI Integrations

Before you begin integrating with Scrini AI, ensure you have the following:

1. Scrini AI Account: An active Scrini AI account with administrative access to generate API keys and configure webhooks. If you don't have one, Sign Up today.
2. API Key: A valid Scrini AI API key for authenticating your API requests. This key grants programmatic access to your Scrini AI data.
3. Basic Programming Knowledge: Familiarity with a programming language (e.g., Python, Node.js, Ruby) and HTTP concepts.
4. Development Environment: A local or cloud-based environment to host your webhook listener and make API calls.
5. Webhook Endpoint: A publicly accessible URL (HTTPS recommended) that can receive POST requests from Scrini AI. Tools like `ngrok` can be useful for local development.
6. Understanding of REST Principles: Knowledge of common HTTP methods (GET, POST, PUT, DELETE) and JSON data structures.

Step-by-step: Implementing Custom Webhook-Driven Workflows

This section outlines the process of setting up a webhook listener and responding to Scrini AI events.

Step 1: Obtain Your Scrini AI API Key

Your API key is essential for authenticating requests to the Scrini AI REST API. Navigate to your Scrini AI account settings, locate the 'API & Integrations' section, and generate a new API key. Treat this key as sensitive information and store it securely.

Step 2: Configure a Webhook Endpoint in Scrini AI

Log into your Scrini AI admin dashboard. Under 'Integrations' or 'Developer Settings', you will find the option to add new webhooks. You'll need to provide:

• Endpoint URL: Your publicly accessible URL where Scrini AI will send event data.
• Secret Key (Optional but Recommended): A shared secret string used to verify the authenticity of incoming webhook payloads.
• Events to Subscribe: Select the specific events (e.g., `candidate.created`, `application.submitted`, `interview.scheduled`) that should trigger a webhook notification.

Step 3: Develop Your Webhook Listener Application

Create a simple application that listens for incoming POST requests at your designated endpoint. This application will parse the JSON payload sent by Scrini AI.

Step 4: Implement Webhook Signature Verification (Best Practice)

To ensure the integrity and authenticity of incoming webhooks, always verify the signature. Scrini AI includes a signature in the request headers (e.g., `X-Scrini-Signature`). Your listener should:

1. Extract the signature from the header.
2. Concatenate the timestamp (also in headers) with the raw request body.
3. Compute an HMAC-SHA256 hash using your configured secret key.
4. Compare your computed hash with the provided signature. If they don't match, reject the request.

Step 5: Process the Webhook Payload

Once verified, parse the JSON payload. Each payload contains an `event` type and relevant `data` about the object that triggered the event. Based on the `event` type, your application can trigger subsequent actions, such as:

• Updating an external ATS or CRM.
• Notifying a Slack channel about a new candidate.
• Triggering a background check service for a candidate in the `offer_extended` stage.
• Initiating a custom workflow standardization process.

Step 6: Make API Calls to Scrini AI (Optional)

Your webhook listener can also make API calls back to Scrini AI to update candidate status, retrieve additional details, or trigger new actions within the OS. Use your API key in the `Authorization` header for all requests.

Code Examples: Python Webhook Listener and API Interaction

Here's a simplified Python Flask example for a webhook listener and an API call using the `requests` library:

Python Flask Webhook Listener Example

from flask import Flask, request, jsonify
import hmac
import hashlib
import os
import json

app = Flask(__name__)

SCRINI_WEBHOOK_SECRET = os.environ.get('SCRINI_WEBHOOK_SECRET', 'your_scrini_webhook_secret')
SCRINI_API_KEY = os.environ.get('SCRINI_API_KEY', 'your_scrini_api_key')
SCRINI_API_BASE_URL = "https://api.scrini.ai/v1"

@app.route('/scrini-webhook', methods=['POST'])
def scrini_webhook():
    signature = request.headers.get('X-Scrini-Signature')
    timestamp = request.headers.get('X-Scrini-Timestamp')
    payload = request.get_data()

    # 1. Verify Signature (Highly Recommended)
    if not verify_webhook_signature(payload, signature, timestamp, SCRINI_WEBHOOK_SECRET):
        print("Webhook signature verification failed.")
        return jsonify({'message': 'Unauthorized'}), 403

    event_data = request.json
    event_type = event_data.get('event')

    print(f"Received Scrini AI event: {event_type}")

    if event_type == 'candidate.created':
        candidate_id = event_data['data']['id']
        candidate_name = event_data['data']['name']
        print(f"New candidate created: {candidate_name} (ID: {candidate_id})")
        # Example: Call Scrini AI API to update candidate status
        update_candidate_status(candidate_id, 'initial_review')
    elif event_type == 'stage.changed':
        candidate_id = event_data['data']['candidate_id']
        new_stage = event_data['data']['new_stage']
        print(f"Candidate {candidate_id} moved to stage: {new_stage}")
        # Example: Trigger an external notification or internal process
        send_slack_notification(f"Candidate {candidate_id} is now in {new_stage}.")
    else:
        print(f"Unhandled event type: {event_type}")

    return jsonify({'status': 'success'}), 200

def verify_webhook_signature(payload, signature, timestamp, secret):
    if not signature or not timestamp:
        return False
    
    signed_payload = f"{timestamp}.{payload.decode('utf-8')}"
    expected_signature = hmac.new(secret.encode('utf-8'), signed_payload.encode('utf-8'), hashlib.sha256).hexdigest()
    return hmac.compare_digest(signature, expected_signature)

def update_candidate_status(candidate_id, status):
    import requests
    headers = {
        'Authorization': f'Bearer {SCRINI_API_KEY}',
        'Content-Type': 'application/json'
    }
    data = {
        'status': status
    }
    try:
        response = requests.put(f"{SCRINI_API_BASE_URL}/candidates/{candidate_id}", headers=headers, json=data)
        response.raise_for_status() # Raise an exception for HTTP errors
        print(f"Successfully updated candidate {candidate_id} status to {status}")
    except requests.exceptions.RequestException as e:
        print(f"Error updating candidate status: {e}")

def send_slack_notification(message):
    # Placeholder for actual Slack integration
    print(f"[SLACK] {message}")

if __name__ == '__main__':
    app.run(port=5000, debug=True)

Troubleshooting Common Integration Issues

Even with careful implementation, issues can arise. Here are common problems and their solutions:

• 401 Unauthorized / Invalid API Key:
  • Issue: Your API requests return a 401 error.
  • Solution: Double-check that your `Authorization` header is correctly formatted (e.g., `Bearer YOUR_API_KEY`) and that the API key itself is valid and hasn't expired or been revoked.
• Webhook Delivery Failures:
  • Issue: Scrini AI reports failed webhook deliveries.
  • Solution: Verify your endpoint URL is publicly accessible and configured for HTTPS. Check your server logs for errors and ensure it's not returning HTTP errors (e.g., 500, 400). Scrini AI provides a webhook delivery log in its dashboard for detailed error messages.
• Signature Verification Mismatch:
  • Issue: Your listener rejects webhooks due to signature verification failures.
  • Solution: Ensure your `SCRINI_WEBHOOK_SECRET` matches the one configured in Scrini AI exactly. Verify that you're signing the correct payload (timestamp + raw request body) and using the correct HMAC-SHA256 algorithm.
• Rate Limit Exceeded (429 Too Many Requests):
  • Issue: Your API calls are being throttled.
  • Solution: Implement exponential backoff and retry logic in your API client. Review Scrini AI's API documentation for specific rate limits and adjust your call frequency.
• Incorrect Payload Parsing:
  • Issue: Your application fails to process the incoming JSON data.
  • Solution: Use a solid JSON parser. Inspect the raw webhook payload from Scrini AI's delivery logs to understand the exact structure and ensure your parsing logic matches.
