What are the Essential Prerequisites for Scrini AI API Integration?

Before embarking on any technical integration project with Scrini AI, it's crucial to ensure your team has the necessary foundational elements in place. These prerequisites pave the way for a smoother development process and a more secure, efficient integration.

A successful technical integration, defined as the smooth data exchange and workflow automation between Scrini AI and external systems, requires careful preparation. Ignoring these initial steps can lead to significant delays, security vulnerabilities, or data inconsistencies.

Key Requirements for Developers and IT Teams

Scrini AI Account & Access: Ensure you have an active Scrini AI organizational account with appropriate administrative permissions to manage API keys and webhooks.
API Credentials: Obtain your unique API Key or set up OAuth 2.0 Client ID and Client Secret for secure authentication. These credentials are vital for programmatic access to Scrini AI's platform.
Understanding of RESTful APIs: A solid grasp of REST principles, HTTP methods (GET, POST, PUT, DELETE), and status codes is fundamental. Scrini AI's APIs are designed around REST conventions for predictability and ease of use.
JSON Data Format Proficiency: All data exchange with Scrini AI APIs occurs in JSON format. Familiarity with JSON parsing and serialization is essential for handling request and response payloads.
Programming Language & Environment: Select a preferred programming language (e.g., Python, Node.js, Java) and ensure your development environment is properly set up to make HTTP requests and handle JSON data.
Network Accessibility: Confirm that your integration environment has outbound access to https://api.scrini.ai and that any inbound webhook endpoints you configure are publicly accessible and secured.
Integration Pattern Strategy: Determine whether your primary integration pattern will be direct API calls for polling/CRUD operations, event-driven webhooks, or using pre-built ATS Integrations and connectors.
Security Best Practices: Understand secure coding practices, environment variable management for sensitive credentials, and webhook signature verification.

How Do You Architect smooth ATS and HRIS Data Synchronization?

Integrating Scrini AI with your existing ATS or HRIS is crucial for creating a cohesive hiring ecosystem. This allows Scrini AI's powerful agents, like Neural Match v4.2 and the Omni-Source Agent, to operate on comprehensive, up-to-date candidate and job data. Here's a step-by-step approach to building a solid data synchronization pipeline.

Step-by-Step Integration Blueprint

1. Authenticate Your Integration with Scrini AI

Secure access is paramount. Scrini AI supports both API Key authentication for simpler use cases and OAuth 2.0 Client Credentials flow for more solid, application-level authorization. OAuth is recommended for production environments requiring higher security.

Example: Obtaining an OAuth Token (Bash/cURL)

curl -X POST \
  https://api.scrini.ai/oauth/token \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -d "grant_type=client_credentials&client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET"

This command will return a JSON object containing your access token, its type (Bearer), and its expiry time. This token must be included in the Authorization header of subsequent API requests.

2. Understand Scrini AI's Core Data Models and Endpoints

Familiarize yourself with Scrini AI's core API resources, particularly /candidates and /jobs. These endpoints allow you to create, retrieve, update, and delete candidate profiles and job postings. Each resource has a well-defined JSON schema that dictates the structure and types of data expected.

/candidates: Manages candidate profiles, including personal details, contact information, skills, experience, and application history.
/jobs: Manages job descriptions, requirements, locations, hiring team details, and status.

3. Choose Your Data Synchronization Strategy

The best strategy depends on your existing systems' capabilities and your real-time data needs:

API Polling: Periodically query Scrini AI's API (e.g., GET /candidates?updatedSince=[timestamp]) or your ATS for new or updated records. This is simpler to implement but can be inefficient and introduce latency.
Webhooks (Event-Driven): Subscribe to Scrini AI events (e.g., candidate.created, job.updated) or configure your ATS to send webhook notifications to Scrini AI. This provides real-time data synchronization and is highly efficient. Scrini AI supports outgoing webhooks to notify your systems about events within its platform.
Direct ATS Connectors: For popular ATS platforms like Greenhouse, Workday, or SAP SuccessFactors, Scrini AI offers pre-built connectors. These are configured via the Scrini AI dashboard, abstracting much of the technical integration complexity. Visit ATS Integrations for more details.

4. Implement Data Flow and Transformation

This involves writing the code to fetch data from one system, transform it to match the target system's schema, and then send it via API. Consider mapping fields carefully to avoid data loss or corruption.

Example Scenario: Syncing a New Candidate from ATS to Scrini AI

When a new candidate applies in your ATS, your integration layer would:

Receive a webhook from your ATS (or poll the ATS API).
Extract relevant candidate data (name, email, resume, applied job ID).
Map ATS fields to Scrini AI's Candidate object schema.
Call Scrini AI's POST /candidates endpoint to create the new candidate.
Handle the response, including success codes or validation errors.

5. Implement solid Error Handling and Idempotency

Integrations are prone to transient failures. Implement comprehensive error handling (retries with exponential backoff for 5xx errors) and ensure your API calls are idempotent where possible. Idempotency means that making the same request multiple times has the same effect as making it once, preventing duplicate records if a retry occurs.

For example, if creating a candidate, include a unique external ID from your ATS to allow Scrini AI to identify and de-duplicate subsequent requests for the same candidate.

6. Thoroughly Test and Monitor Your Integration

Always test your integrations in a sandbox or staging environment before deploying to production. Perform unit tests, integration tests, and end-to-end tests to validate data flow, error handling, and performance. Once in production, set up monitoring and alerting for API errors, webhook delivery failures, and data discrepancies. Scrini AI's Hiring Dashboard can provide insights into system activity and integration health.

Code Examples: Practical Scrini AI API Snippets

Here are practical code snippets to illustrate common integration tasks with Scrini AI's API. These examples use Python, a popular choice for integration scripting due to its readability and extensive libraries.

Python Example: Creating a New Candidate in Scrini AI

import requests
import json

API_BASE_URL = "https://api.scrini.ai/v1"
AUTH_TOKEN = "YOUR_BEARER_TOKEN"  # Obtain this from Step 1 (OAuth Token)

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

candidate_data = {
    "firstName": "Alice",
    "lastName": "Wonderland",
    "email": "alice.wonderland@example.com",
    "phoneNumber": "+15551234567",
    "source": "IntegratedATS_XYZ",
    "externalId": "ATS_CAND_7890", # Unique ID from your ATS for idempotency
    "jobAppliedId": "job_abc123",  # If linking to an existing job in Scrini AI
    "status": "ApplicationReceived"
}

try:
    response = requests.post(f"{API_BASE_URL}/candidates", headers=headers, data=json.dumps(candidate_data))
    response.raise_for_status()  # Raises an HTTPError for bad responses (4xx or 5xx)
    print("Candidate created successfully:", response.json())
    print("New Scrini AI Candidate ID:", response.json().get("id"))
except requests.exceptions.HTTPError as e:
    print(f"HTTP Error creating candidate: {e}")
    print(f"Response status code: {e.response.status_code}")
    print(f"Response body: {e.response.text}")
except Exception as e:
    print(f"An unexpected error occurred: {e}")

Illustrative Webhook Payload from Scrini AI (Candidate Created Event)

When an event occurs within Scrini AI, such as a candidate being created (either manually or via another integration), Scrini AI can send a webhook notification to your configured endpoint. This allows for real-time updates in your systems, supporting End-to-End Automation.

{
    "eventType": "candidate.created",
    "timestamp": "2026-08-15T14:30:00Z",
    "data": {
        "id": "cand_xyz123",
        "externalId": "ATS_CAND_7890",
        "firstName": "Alice",
        "lastName": "Wonderland",
        "email": "alice.wonderland@example.com",
        "jobAppliedId": "job_abc123",
        "status": "ApplicationReceived",
        "createdAt": "2026-08-15T14:29:55Z"
    },
    "scriniAccountId": "org_789",
    "signature": "sha256=a1b2c3d4e5f6..." // For verification
}

Your webhook handler should always verify the signature to ensure the payload truly originated from Scrini AI.

Troubleshooting Common Integration Challenges

Even with careful planning, technical integrations can present challenges. Here are common issues and practical troubleshooting steps.

Authentication Errors (HTTP 401 Unauthorized, 403 Forbidden):
- Problem: Invalid API key, expired OAuth token, or insufficient permissions.
- Solution: Double-check your API key or regenerate your OAuth token. Verify that your API credentials have the necessary scopes/permissions for the endpoints you're trying to access.
Rate Limiting (HTTP 429 Too Many Requests):
- Problem: Your integration is sending too many requests within a short period, exceeding Scrini AI's API rate limits.
- Solution: Implement exponential backoff and retry logic in your integration. Review Scrini AI's API documentation for specific rate limit thresholds and consider batching requests where appropriate.
Data Validation Errors (HTTP 400 Bad Request):
- Problem: The data sent in your API request does not conform to Scrini AI's expected JSON schema (e.g., missing required fields, incorrect data types).
- Solution: Carefully review the API response body for specific error messages detailing which fields are invalid. Cross-reference with Scrini AI's API documentation for correct data formats and required fields.
Webhook Delivery Failures:
- Problem: Scrini AI is unable to deliver webhook payloads to your endpoint (e.g., your server is down, firewall blocking, invalid URL).
- Solution: Ensure your webhook URL is correct and publicly accessible. Check your server logs for incoming requests and any processing errors. Verify your firewall rules. Utilize Scrini AI's webhook delivery logs (if available in the developer portal) to diagnose failures.
Network Timeouts or Server Errors (HTTP 5xx):
- Problem: Transient issues on Scrini AI's side or network connectivity problems.
- Solution: Implement solid retry mechanisms with exponential backoff. Monitor Scrini AI's status page for any service outages. If persistent, contact Scrini AI support with request IDs and timestamps.
Data Discrepancies:
- Problem: Data in Scrini AI doesn't match your source system, or vice-versa.
- Solution: Implement comprehensive logging for all API requests and responses. Periodically run reconciliation scripts to compare data between systems and identify mismatches. Ensure your unique identifiers (like externalId) are consistently used.
