How to Integrate Your ATS with Scrini AI: A Step-by-Step Technical Guide

Integrating your ATS with Scrini AI involves configuring secure API communication for data synchronization and setting up real-time event notifications via webhooks. This guide outlines the core technical steps.

Step 1: Authentication and Authorization

All programmatic interactions with the Scrini AI API require secure authentication to protect your data. Scrini AI primarily uses API keys for server-to-server communication, combined with strict IP whitelisting for enhanced security and access control.

1. Generate API Key: Navigate to your Scrini AI developer settings within the platform. Generate and securely store a new, unique API key. Treat this key like a password.
2. IP Whitelisting: Provide your outgoing server IP addresses to Scrini AI support or configure them directly in your Scrini AI organization settings (if available) to whitelist access. This ensures only authorized servers can make requests.

Example: Authenticating a curl Request

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

Important: Replace YOUR_SCRINI_AI_API_KEY with your actual, securely stored API key.

Step 2: Synchronizing Job and Candidate Data via API

The primary objective of ATS integration is to maintain consistent and up-to-date job and candidate data between your ATS and Scrini AI. Scrini AI provides solid RESTful APIs for creating, updating, and querying essential data entities.

1. Initial Data Ingestion: Perform an initial bulk import of your existing job requisitions and candidate profiles from your ATS to Scrini AI. This establishes the baseline data.
   • Jobs Endpoint: Use POST /v1/jobs for new jobs or PUT /v1/jobs/{job_id} for updates.
   • Candidates Endpoint: Use POST /v1/candidates for new candidates or PUT /v1/candidates/{candidate_id} for updates.
2. Delta Synchronization: Implement logic to send incremental updates to Scrini AI whenever a job or candidate record changes in your ATS. This can be efficiently triggered by webhook events from your ATS or by scheduled polling mechanisms.

Example: Creating a New Job in Scrini AI

POST https://api.scrini.ai/v1/jobs\nContent-Type: application/json\nAuthorization: Bearer YOUR_SCRINI_AI_API_KEY\n\n{\n  "atsJobId": "ATS_JOB_XYZ123",\n  "title": "Senior AI Integration Architect",\n  "description": "Designing and implementing complex AI integrations across enterprise HR systems...",\n  "status": "OPEN",\n  "department": "Engineering",\n  "location": "Remote, USA",\n  "hiringTeam": ["user_id_1", "user_id_2"],\n  "customFields": {\n    "salaryRange": "$180k - $220k",\n    "projectLoad": "High"\n  }\n}

Step 3: Configuring Webhooks for Real-Time Event Handling

Webhooks are crucial for enabling Scrini AI to notify your ATS about critical events in real time. This includes events such as a candidate being shortlisted, an interview scheduled, or an offer extended. This ensures real-time bidirectional data flow and empowers solid Workflow Standardization.

1. Register Webhook Endpoint: In your Scrini AI settings, specify the URL where your system will receive webhook POST requests.
   • Endpoint Example: https://your-ats-system.com/scrini-ai-webhook
   • Events: Select the specific events you wish to subscribe to (e.g., candidate.status.updated, interview.scheduled, job.closed).
2. Implement Webhook Listener: Develop an endpoint in your ATS or a dedicated middleware to process incoming webhook payloads. Critically, verify the signature for security to ensure the request's authenticity.

Example: Webhook Payload for Candidate Status Update

POST https://your-ats-system.com/scrini-ai-webhook\nContent-Type: application/json\nX-ScriniAI-Signature: sha256=generated_signature\n\n{\n  "eventId": "evt_abc123def456",\n  "eventType": "candidate.status.updated",\n  "timestamp": "2026-08-15T14:30:00Z",\n  "data": {\n    "candidateId": "scr_cand_12345",\n    "atsCandidateId": "ATS_CAND_7890",\n    "jobId": "scr_job_56789",\n    "atsJobId": "ATS_JOB_XYZ123",\n    "oldStatus": "Applied",\n    "newStatus": "Shortlisted",\n    "updatedBy": "Scrini AI Neural Match Agent"\n  }\n}

Security Note: Always verify the X-ScriniAI-Signature header using your shared secret to ensure the webhook originated from Scrini AI and has not been tampered with. This is vital for data integrity.

Real-World Scenario: Automating Candidate Progression for High-Volume Hiring

Consider a large enterprise that uses Scrini AI to process thousands of applications for their high-volume hiring roles. Their legacy ATS needs to reflect every stage change automatically.

• When a new candidate applies in the ATS, a configured webhook from the ATS triggers a POST /v1/candidates API call to Scrini AI, creating a new candidate record.
• Scrini AI's Candidate Ranking & Matching capabilities, powered by Neural Match v4.2, processes the application, identifies top matches, and initiates further screening.
• Once the candidate successfully passes initial screening by an AI Video Agent and is automatically moved to a "Shortlisted" status within Scrini AI.
• Scrini AI then sends a candidate.status.updated webhook to the enterprise's ATS.
• The ATS's webhook listener receives this notification, validates its signature, and automatically updates the candidate's status in the ATS to "Shortlisted." This action can then trigger the next automated step in their internal workflow, such as sending an interview invite or notifying the hiring manager, all without any manual intervention. This dramatically reduces Time to Hire and improves efficiency.

Troubleshooting Common Integration Issues

Even with meticulous planning, integration challenges can arise. Here are common issues and their effective solutions:

• Authentication Errors (HTTP 401 Unauthorized):
  • Cause: Invalid API key, incorrect Authorization header format, or your server's IP address not being whitelisted.
  • Solution: Double-check your API key, ensure the Bearer YOUR_API_KEY format is correct, and confirm your server's public IP is correctly registered and whitelisted in Scrini AI.
• Data Mismatch or Validation Errors (HTTP 400 Bad Request):
  • Cause: Sending malformed JSON, missing required fields, or providing data in an incorrect format according to Scrini AI's data schema.
  • Solution: Refer to the official Scrini AI API documentation for specific endpoint requirements. Use a JSON validator and ensure all mandatory fields are present and correctly formatted.
• Webhook Delivery Failures:
  • Cause: Your webhook endpoint is not publicly accessible, returns non-2xx HTTP status codes, or a firewall is blocking Scrini AI's outgoing requests.
  • Solution: Ensure your endpoint is publicly reachable via HTTPS, configured to respond with a 200 OK status to indicate successful receipt, and review any active firewall rules. Check Scrini AI's webhook delivery logs for detailed error messages.
• Rate Limiting (HTTP 429 Too Many Requests):
  • Cause: Sending too many API requests within a short period, exceeding defined limits.
  • Solution: Implement solid exponential backoff and retry mechanisms in your integration logic. Monitor X-RateLimit-Remaining headers in API responses to proactively manage your request volume.
• Idempotency Issues (Duplicate Resource Creation):
  • Cause: Accidental duplicate creation of resources (e.g., candidates or jobs) due to retries without proper idempotency handling.
  • Solution: For POST requests that create resources, utilize the X-Idempotency-Key header (if supported by Scrini AI for the specific endpoint). This unique key ensures that the same request, if sent multiple times, is processed only once, preventing duplicates.
