API Integration for Custom Hiring Workflows How to Empower Your Talent Acquisition

Overview What is Scrini AI's API and Why Use It for Custom Workflows?

In March 2026, the competitive field for talent acquisition demands more than just efficiency; it requires intelligent automation. Disconnected systems and manual handoffs are no longer viable. According to recent industry research by PwC, 72% of companies report that manual data entry and siloed systems are significant bottlenecks, increasing time-to-hire and detracting from the candidate experience. This is where Scrini AI's solid Application Programming Interface (API) becomes indispensable.

The Scrini AI API is a powerful RESTful interface designed to enable programmatic interaction with our Agentic Hiring OS. It allows developers, IT teams, and tech-savvy HR operations professionals to extend, customize, and automate hiring workflows far beyond out-of-the-box configurations. This capability is crucial for organizations looking to achieve end-to-end automation and truly streamline their talent acquisition processes.

What are the core benefits of integrating custom workflows with Scrini AI's API?

• Enhanced Efficiency: Automate repetitive tasks, reducing manual effort and processing times.
• Real-time Data Synchronization: Ensure consistent and up-to-date information across all your HR systems, including ATS/HRIS.
• Custom Logic & Personalization: Implement unique business rules and tailored candidate experiences specific to your organizational needs.
• Competitive Advantage: Accelerate your hiring velocity and improve candidate quality by using intelligent automation.
• Scalability: Design workflows that smoothly scale with your hiring volume, essential for high-volume hiring scenarios.

A common misconception is that APIs are solely for hardcore developers. While technical expertise is required, the ultimate goal is to empower HR leaders and recruiters with more agile and integrated tools. The Scrini AI API serves as the backbone for creating a truly standardized and automated workflow ecosystem.

Prerequisites What You Need Before You Start Integrating?

Before diving into the technical implementation, ensure you have the following in place to guarantee a smooth integration process.

1. Scrini AI Account: You need an active Scrini AI account with administrative privileges to access API settings.
2. API Key: A unique API key, typically a bearer token, is essential for authenticating your requests. This key acts as your credentials for interacting with the Scrini AI API. Treat it like a password and keep it secure.
3. Understanding of REST APIs: Familiarity with RESTful principles, HTTP methods (GET, POST, PUT, DELETE), and JSON data format is fundamental.
4. Development Environment: Tools such as Postman for testing API endpoints, cURL for command-line interactions, or a programming language like Python, Node.js, or Java for building solid integrations.
5. Target System Documentation: If you're integrating with an existing ATS, CRM, or HRIS, have its API documentation readily available for smooth data mapping.

Step-by-Step Integrating Custom Workflows with Scrini AI's API

Integrating custom hiring workflows with Scrini AI involves a structured approach to ensure reliability and scalability. Gartner predicts that by 2027, 80% of organizations will have implemented AI-powered solutions in at least one HR function, underscoring the necessity of solid integration strategies today.

Step 1 Obtain Your API Credentials

Access your Scrini AI dashboard, navigate to the “Settings” or “Developer” section, and generate a new API key. This key is typically a long alphanumeric string. Store it securely, preferably using environment variables or a secrets manager, and never hardcode it directly into your applications.

Step 2 Understand Key API Endpoints and Data Schemas

Scrini AI's API exposes various endpoints to manage resources like jobs, candidates, and workflows. Key endpoints for custom workflows include:

• POST /api/v1/jobs: Create a new job posting within Scrini AI.
• POST /api/v1/candidates: Add a new candidate or update an existing one.
• POST /api/v1/workflows/{workflowId}/execute: Trigger specific steps or initiate custom workflows.
• GET /api/v1/webhooks: Manage and retrieve webhook configurations.

Familiarize yourself with the JSON data schemas for each resource (e.g., Job object, Candidate object) to ensure correct data formatting in your requests.

Step 3 Authenticate Your Requests

All requests to the Scrini AI API require authentication using your API key. This is typically done via a Bearer Token in the HTTP Authorization header.

Authorization: Bearer YOUR_SCRINI_AI_API_KEY

Without proper authentication, your requests will be rejected, resulting in a 401 Unauthorized error.

Step 4 Design Your Custom Workflow Logic

Before coding, map out the desired flow. A common scenario might be:

1. A new candidate applies through your existing ATS.
2. Your integration uses the Scrini AI API to create this candidate in Scrini AI.
3. Scrini AI's Resume Screening and Candidate Ranking & Matching capabilities process the application.
4. Based on ranking, Scrini AI triggers an AI Video Interview.
5. Upon completion, a webhook event is sent to your system.
6. Your system updates the candidate's status in the ATS and initiates the next human-led step.

Step 5 Implement API Calls and Webhook Handlers

Based on your workflow design, implement the necessary API calls to Scrini AI and set up webhook endpoints in your system to receive real-time updates. Webhooks are critical for event-driven automation, enabling Scrini AI to push information to your system without constant polling.

Code Examples Practical Snippets for Common Integrations

Creating a New Candidate (Python)

This Python snippet demonstrates how to add a new candidate to Scrini AI.

import requests
import json

API_KEY = "YOUR_SCRINI_AI_API_KEY"
BASE_URL = "https://api.scrini.ai/v1"

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

new_candidate_data = {
    "firstName": "Jane",
    "lastName": "Doe",
    "email": "jane.doe@example.com",
    "phone": "+15551234567",
    "jobId": "job_uuid_123", # Optional, link to an existing job
    "source": "ATS Integration"
}

response = requests.post(f"{BASE_URL}/candidates", headers=headers, data=json.dumps(new_candidate_data))

if response.status_code == 200:
    print("Candidate created successfully:")
    print(json.dumps(response.json(), indent=2))
else:
    print(f"Error creating candidate: {response.status_code}")
    print(response.text)

Handling a Webhook Event (Node.js/Express)

This Node.js example shows a basic Express server endpoint for receiving and processing a candidate.interview.completed webhook event.

const express = require('express');
const bodyParser = require('body-parser');
// const crypto = require('crypto'); // For webhook signature verification

const app = express();
const PORT = 3000;

// const WEBHOOK_SECRET = 'YOUR_WEBHOOK_SECRET'; // For verification

app.use(bodyParser.json());

app.post('/scrini-webhook', (req, res) => {
    // OPTIONAL: Verify webhook signature for security
    // const signature = req.headers['x-scrini-signature'];
    // const payload = JSON.stringify(req.body);
    // const hmac = crypto.createHmac('sha256', WEBHOOK_SECRET);
    // hmac.update(payload);
    // const digest = hmac.digest('hex');
    // if (digest !== signature) {
    //     console.error('Webhook signature verification failed!');
    //     return res.sendStatus(401);
    // }

    const event = req.body;
    console.log('Received Scrini AI Webhook Event:', event.eventType);

    switch (event.eventType) {
        case 'candidate.interview.completed':
            console.log(`Interview completed for Candidate ID: ${event.data.candidateId}`);
            // Process the interview results, update ATS, etc.
            break;
        case 'job.created':
            console.log(`New Job Created: ${event.data.jobTitle}`);
            break;
        // ... handle other event types
        default:
            console.log(`Unhandled event type: ${event.eventType}`);
    }

    res.status(200).send('Webhook received successfully');
});

app.listen(PORT, () => {
    console.log(`Webhook server listening on port ${PORT}`);
});

Fetching Job Details (cURL)

A quick way to test API endpoints from your terminal.

curl -X GET \n  https://api.scrini.ai/v1/jobs/your_job_id_here \n  -H 'Authorization: Bearer YOUR_SCRINI_AI_API_KEY' \n  -H 'Content-Type: application/json'

Troubleshooting Common Issues and Their Solutions

API integrations can encounter various issues. Here are some common problems and how to resolve them.

• 401 Unauthorized: This almost always means your API key is missing, incorrect, or expired. Double-check your Authorization: Bearer header and ensure the key is valid.
• 400 Bad Request: The request body is malformed or missing required fields. Compare your JSON payload against the Scrini AI API documentation for the specific endpoint. Ensure all data types and field names are correct.
• 404 Not Found: The specified endpoint or resource ID does not exist. Verify the URL path and any IDs (e.g., jobId, candidateId) in your request.
• 429 Too Many Requests (Rate Limiting): You've exceeded the API's rate limit. Implement exponential backoff in your client to gracefully retry requests after a delay. Consult Scrini AI's API documentation for specific rate limits.
• Webhook Delivery Failures: Ensure your webhook endpoint is publicly accessible and returns a 200 OK status. Check your server logs for errors and confirm any firewall rules are not blocking incoming requests. Implement webhook signature verification for added security and to ensure the request truly originated from Scrini AI.
• Data Inconsistencies: If data isn't synchronizing correctly, review your data mapping between systems. Ensure ID fields are consistently used for updates rather than creating duplicates.
