Step-by-Step Guide Implementing Scrini AI Integrations

This section outlines a practical process for integrating Scrini AI into your talent ecosystem, focusing on common patterns.

1. Understand Scrini AI's Core API Endpoints and Data Flow

Scrini AI's API is organized around core entities like Candidates, Job Requisitions, and Interactions. Understanding the available endpoints and their data schemas is the first step.

Common API Entities:

• /candidates: Manage candidate profiles.
• /jobs: Manage job requisitions.
• /events: Send custom events to trigger Scrini AI workflows.
• /webhooks: Configure and manage webhook subscriptions.

Typical data flows involve pushing candidate information from your ATS to Scrini AI, receiving updates on candidate status, or triggering custom actions based on system events. For instance, when a new job is created in your ATS, it can be pushed to Scrini AI for AI Candidate Sourcing.

2. API Authentication and Authorization

Scrini AI primarily uses API keys for authentication. Your API key should be treated like a password and stored securely.

To authenticate, include your API key in the Authorization header for every request, formatted as a Bearer token.

curl -X GET \ 
  https://api.scrini.ai/v1/jobs \ 
  -H 'Authorization: Bearer YOUR_SCRINI_API_KEY'

Replace YOUR_SCRINI_API_KEY with the actual key provided in your Scrini AI account settings. Failure to provide a valid key will result in a 401 Unauthorized error.

3. Integrating Core Candidate Data Push and Pull

A fundamental integration involves synchronizing candidate data. You can push new candidates to Scrini AI or retrieve existing candidate profiles.

Example: Creating a New Candidate

To add a candidate, make a POST request to the /candidates endpoint with the candidate's details in JSON format. Ensure your payload adheres to Scrini AI's candidate schema.

{
  "first_name": "Jane",
  "last_name": "Doe",
  "email": "jane.doe@example.com",
  "phone": "+15551234567",
  "resume_url": "https://example.com/jane_doe_resume.pdf",
  "source": "ATS-Integration",
  "custom_fields": {
    "current_company": "Acme Corp",
    "years_experience": 5
  }
}

curl -X POST \ 
  https://api.scrini.ai/v1/candidates \ 
  -H 'Content-Type: application/json' \ 
  -H 'Authorization: Bearer YOUR_SCRINI_API_KEY' \ 
  -d '{
        "first_name": "Jane",
        "last_name": "Doe",
        "email": "jane.doe@example.com",
        "phone": "+15551234567",
        "resume_url": "https://example.com/jane_doe_resume.pdf",
        "source": "ATS-Integration",
        "custom_fields": {
          "current_company": "Acme Corp",
          "years_experience": 5
        }
      }'

Example: Retrieving Candidate Status

To fetch a candidate's details and current status, use a GET request to /candidates/{candidate_id}.

curl -X GET \ 
  https://api.scrini.ai/v1/candidates/cand_abc123def456 \ 
  -H 'Authorization: Bearer YOUR_SCRINI_API_KEY'

4. using Webhooks for Real-Time Updates

Webhooks are crucial for real-time, event-driven integrations. Instead of constantly polling the API, Scrini AI can notify your system when specific events occur. This reduces API calls and ensures immediate data synchronization. Scrini AI offers webhooks for events like candidate.status_updated, interview.scheduled, or assessment.completed.

Configuring a Webhook Endpoint

First, you need an endpoint on your server that can receive HTTP POST requests from Scrini AI. Then, configure the webhook within Scrini AI's settings or via the API.

{
  "event_type": "candidate.status_updated",
  "target_url": "https://your-server.com/scrini-webhook-receiver",
  "secret": "YOUR_WEBHOOK_SECRET_KEY"
}

curl -X POST \ 
  https://api.scrini.ai/v1/webhooks \ 
  -H 'Content-Type: application/json' \ 
  -H 'Authorization: Bearer YOUR_SCRINI_API_KEY' \ 
  -d '{
        "event_type": "candidate.status_updated",
        "target_url": "https://your-server.com/scrini-webhook-receiver",
        "secret": "YOUR_WEBHOOK_SECRET_KEY"
      }'

The secret is used to verify the authenticity of the webhook payload, preventing spoofing.

Receiving and Processing Webhook Payloads (Python Example)

A simple Flask application to receive webhooks:

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

app = Flask(__name__)

WEBHOOK_SECRET = "YOUR_WEBHOOK_SECRET_KEY"

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

    # Verify webhook signature
    expected_signature = hmac.new(WEBHOOK_SECRET.encode('utf-8'), payload, hashlib.sha256).hexdigest()
    if not hmac.compare_digest(signature, expected_signature):
        return jsonify({'error': 'Invalid signature'}), 401

    event_data = request.json
    event_type = event_data.get('event_type')
    candidate_id = event_data.get('data', {}).get('candidate_id')
    new_status = event_data.get('data', {}).get('new_status')

    print(f"Received webhook: {event_type} for Candidate {candidate_id}, new status: {new_status}")
    # Implement your logic here, e.g., update ATS, send notification

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

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

5. Custom Workflow Configuration through Scrini AI

Scrini AI allows you to define custom workflows and automation rules based on events and data. While many can be configured directly within the Workflow Standardization UI, advanced users can use API events to trigger bespoke actions within Scrini AI or their integrated systems. For example, a custom event sent via API (e.g., candidate.external_assessment_completed) could trigger an Outreach Agent action to send a personalized follow-up email.

Troubleshooting Common Integration Challenges

Even with careful planning, integration challenges can arise. Here are common issues and how to resolve them:

1. 401 Unauthorized: Invalid API Key:
   • Symptom: API requests return a 401 status code.
   • Resolution: Double-check your API key for typos. Ensure it's included in the Authorization: Bearer YOUR_KEY header. Verify the key hasn't expired or been revoked.
2. 400 Bad Request: Malformed Request or Schema Mismatch:
   • Symptom: The API rejects your payload.
   • Resolution: Carefully review Scrini AI's API documentation for the specific endpoint. Ensure your JSON payload matches the required data schema, including data types, mandatory fields, and formatting. Use a tool like Postman to validate your JSON before sending.
3. 429 Too Many Requests: Rate Limiting:
   • Symptom: Requests are temporarily blocked after a certain volume.
   • Resolution: Implement exponential backoff and retry logic in your integration code. Monitor your API usage and adjust your request frequency. If sustained high volume is needed, contact Scrini AI support for potential limit adjustments.
4. Webhook Delivery Failures:
   • Symptom: Your endpoint isn't receiving webhooks, or they're failing silently.
   • Resolution: Verify your webhook endpoint is publicly accessible and responding with a 200 OK status code. Check server logs for errors. Ensure firewalls are not blocking incoming requests from Scrini AI's IP ranges (if provided). Inspect the X-Scrini-Signature for verification issues.
5. Data Inconsistencies or Missing Information:
   • Symptom: Data pushed to Scrini AI doesn't appear correctly, or data pulled is incomplete.
   • Resolution: Revisit your data mapping document. Ensure correct field names, data types, and transformations are applied. Use Scrini AI's Hiring Dashboard or internal debugging tools to inspect the data stored.

Next Steps and Best Practices for Scalable Integrations

Building solid integrations goes beyond initial setup. Consider these best practices for long-term maintainability and scalability:

• API Versioning: Always specify the API version (e.g., /v1/) in your requests. Design your code to gracefully handle potential future API version changes.
• solid Error Handling and Retries: Implement comprehensive error handling, especially for network issues and transient API errors. Use retry mechanisms with exponential backoff to ensure reliability.
• Security Best Practices: Store API keys and webhook secrets securely, ideally in environment variables or a secret management service. Validate all incoming data, especially from webhooks.
• Monitoring and Logging: Implement detailed logging for all API requests and responses, webhook events, and any processing errors. Set up monitoring and alerts for integration failures.
• Thorough Testing: Develop automated tests for your integration code, including unit tests, integration tests, and end-to-end tests that simulate real-world scenarios.
• Idempotent Operations: Design your integration to handle duplicate requests without unintended side effects, especially for operations like creating resources.
• Documentation: Keep your integration code well-documented, explaining data flows, configuration, and maintenance procedures for future developers.
