Prerequisites for Scrini AI API Success

Before diving into specific integration patterns, ensure your team has the foundational elements in place. Proper preparation is key to a smooth and secure integration experience.

Essential Technical Foundations

1. Scrini AI Account and API Key: You will need an active Scrini AI account and a generated API key for authentication. Treat this key as sensitive information, similar to a password.
2. Understanding Scrini AI's API Documentation: Familiarize yourself with our RESTful API endpoints, request/response formats, authentication methods (typically Bearer Token with your API key), and rate limits.
3. Data Mapping Strategy: Clearly define how data fields from your existing systems (e.g., ATS candidate profiles) will map to Scrini AI's data schemas. This is critical for data integrity.
4. Development Environment: Set up a secure development environment with your preferred programming language (Python, Node.js, Java, etc.) and HTTP client library.
5. Access to Existing System APIs: Ensure you have the necessary API keys and documentation for your Applicant Tracking System (ATS) or other systems you intend to integrate with Scrini AI. Access to ATS Integrations will be pivotal here.

Implementing Core Integrations, A Step-by-Step with Scrini AI

Let's walk through a common integration scenario: pushing candidate application data from an external ATS into Scrini AI, using its Neural Match v4.2 and other intelligent capabilities.

Step 1 Authenticate Your Application

All requests to the Scrini AI API require authentication. We use a bearer token approach where your API key is sent in the Authorization header.

Authorization: Bearer YOUR_SCRINI_AI_API_KEY

Step 2 Understand Scrini AI's Data Schemas

Scrini AI's API endpoints are designed for clear, structured data exchange. For candidate management, the primary endpoint is /candidates. A typical JSON payload for creating a new candidate might look like this:

{
    "external_id": "ATS_CANDIDATE_ABC123",
    "first_name": "Jane",
    "last_name": "Doe",
    "email": "jane.doe@example.com",
    "phone": "+15551234567",
    "job_id": "SCRINI_JOB_XYZ456",
    "status": "Applied",
    "source": "LinkedIn",
    "resume_url": "https://yourats.com/resumes/jane_doe.pdf",
    "metadata": {
        "ats_link": "https://yourats.com/candidate/ABC123"
    }
}

Note the external_id field, which is crucial for linking records between your ATS and Scrini AI.

Step 3 Push Candidate Data from Your ATS

Once a candidate applies or reaches a specific stage in your ATS, you can programmatically send their data to Scrini AI using an API call. Here's a Python example:

import requests
import json

SCRINI_API_BASE_URL = "https://api.scrini.ai/v1"
SCRINI_API_KEY = "YOUR_SCRINI_AI_API_KEY"

candidate_data = {
    "external_id": "ATS_CANDIDATE_1234",
    "first_name": "Michael",
    "last_name": "Scott",
    "email": "michael.scott@dundermifflin.com",
    "job_id": "SCRINI_JOB_5678", # This would be a Scrini AI job ID
    "status": "New Application",
    "source": "Company Website",
    "resume_url": "https://yourats.com/resumes/michael_scott.pdf"
}

headers = {
    "Authorization": f"Bearer {SCRINI_API_KEY}",
    "Content-Type": "application/json"
}

try:
    response = requests.post(f"{SCRINI_API_BASE_URL}/candidates", headers=headers, data=json.dumps(candidate_data))
    response.raise_for_status() # Raises HTTPError for bad responses (4xx or 5xx)

    print("Candidate sent successfully to Scrini AI:")
    print(json.dumps(response.json(), indent=2))

except requests.exceptions.HTTPError as err:
    print(f"HTTP Error: {err.response.status_code} - {err.response.text}")
except requests.exceptions.RequestException as err:
    print(f"An error occurred: {err}")

This snippet demonstrates how to initiate the data transfer. Scrini AI then processes this candidate, potentially triggering further actions like Candidate Ranking & Matching or initiating an automated Outreach Agent sequence.

Step 4 Receive Real-time Updates with Webhooks

For bidirectional integration, Scrini AI supports webhooks to notify your systems of events in real time. For example, when a candidate's status changes after an AI Video Interview or a Role Assessment, Scrini AI can send a POST request to a configured endpoint on your server.

To set up a webhook, you'd configure a URL in your Scrini AI settings. When an event occurs (e.g., candidate.status_updated), Scrini AI sends a JSON payload to your webhook URL:

{
    "event": "candidate.status_updated",
    "timestamp": "2026-05-15T10:00:00Z",
    "data": {
        "scrini_candidate_id": "SCRINI_CANDIDATE_UID",
        "external_id": "ATS_CANDIDATE_1234",
        "old_status": "New Application",
        "new_status": "Shortlisted by AI",
        "job_id": "SCRINI_JOB_5678"
    }
}

Your server would then process this payload and update the corresponding candidate record in your ATS, ensuring data consistency across platforms.

Advanced Integration Patterns, Custom Workflows and Beyond

Beyond basic data synchronization, Scrini AI's architecture enables highly sophisticated integration patterns. These empower organizations to build truly agentic hiring operations.

Orchestrating Agentic Workflows

Scrini AI's API allows you to programmatically configure and trigger custom workflows. Imagine a scenario where a high-potential candidate, identified by Neural Match v4.2, automatically triggers a personalized email sequence via the AI Email Outreach capability, followed by an Auto Scheduling request for an interview. All of this can be orchestrated via API calls and webhook responses, turning recruitment into a proactive, intelligent system.

The Power of Bidirectional Data Flow

True integration excellence comes from bidirectional data flow. Your ATS might push candidate data to Scrini AI for intelligent screening. Scrini AI then processes, assesses, and updates candidate statuses. These updates flow back to your ATS via webhooks, keeping all systems synchronized. This continuous loop of data exchange and action is how an agentic OS delivers maximum value, ensuring timely follow-ups and reducing manual interventions across the entire hiring funnel.

Troubleshooting Common API Integration Challenges

Even with meticulous planning, integration issues can arise. Understanding common pitfalls and their solutions is crucial for maintaining solid connections.

Common Pitfalls and Solutions

• Authentication Errors (401 Unauthorized):
  • Issue: Invalid or missing API key, or expired token.
  • Solution: Double-check your API key. Ensure it's correctly placed in the Authorization: Bearer header. Regenerate if necessary.
• Data Validation Errors (400 Bad Request):
  • Issue: Request payload does not match Scrini AI's expected data schema, missing required fields, or incorrect data types.
  • Solution: Refer strictly to the Scrini AI API documentation for expected JSON structures and field requirements. Use clear error messages from the API response to pinpoint the exact issue.
• Resource Not Found (404 Not Found):
  • Issue: Attempting to access an endpoint that doesn't exist, or referencing a non-existent resource ID (e.g., an invalid job_id).
  • Solution: Verify the API endpoint URL and ensure that any IDs passed (like scrini_job_id or scrini_candidate_id) are valid and exist in Scrini AI.
• Rate Limiting (429 Too Many Requests):
  • Issue: Sending too many requests to the API within a short period.
  • Solution: Implement exponential backoff and retry logic in your integration code. Monitor X-RateLimit-* headers in API responses to understand current limits and usage.
• Webhook Delivery Failures:
  • Issue: Your webhook endpoint isn't receiving payloads, or fails to process them correctly.
  • Solution: Ensure your webhook URL is publicly accessible and configured to accept POST requests. Check your server logs for errors when processing webhook payloads. Scrini AI typically includes a retry mechanism for failed deliveries.
