This guide cuts past the fluff and gets straight to how you can fetch job application data reliably, securely, and at scale. This article is part of a broader series on the ATS API, including deep dives on authentication, rate limits, pagination, and best practices. You can explore the complete guide [here](/blog/ats-integration-guide/). **Prerequisites** ----------------- Before you start calling the API, make sure you have: - Valid OAuth 2.0 credentials (Client ID + Client Secret) - Understanding of REST and JSON structures - A Python environment with `requests` installed **Useful Endpoints** -------------------- - Get all job applications → `/staffing/v2/job-applications` - Get a specific application → `/staffing/v2/job-applications/{job-application-id}` **Step-by-Step Guide** ---------------------- ### **1. Generate an OAuth 2.0 Token** ``` import requests def get_oauth_token(client_id, client_secret): url = 'https://auth.adp.com/oauth/v2/token' headers = {'Content-Type': 'application/x-www-form-urlencoded'} data = {'grant_type': 'client_credentials'} response = requests.post(url, headers=headers, data=data, auth=(client_id, client_secret)) return response.json().get('access_token') ``` ### **2. Fetch All Job Applications** ``` def get_all_job_applications(token): url = 'https://api.adp.com/staffing/v2/job-applications' headers = { 'Authorization': f'Bearer {token}', 'Content-Type': 'application/json', 'roleCode': 'practitioner' } params = {'$select': 'itemID,jobRequisitionReference,applicationStatusCode'} response = requests.get(url, headers=headers, params=params) return response.json() ``` ### **3. Fetch a Single Job Application** ``` def get_job_application(token, job_application_id): url = f'https://api.adp.com/staffing/v2/job-applications/{job_application_id}' headers = { 'Authorization': f'Bearer {token}', 'Content-Type': 'application/json', 'roleCode': 'practitioner' } response = requests.get(url, headers=headers) return response.json() ``` **Common Pitfalls** ------------------- Developers integrating ADP Workforce Now often trip over the same issues. Keep these in check: **1. Token expiry sneaking up on you** ADP tokens expire quickly; build auto-refresh into your workflow. **2. Missing or incorrect `roleCode`** This header is mandatory and impacts what data you can see. **3. Pagination confusion** ADP won’t return everything in one shot, use `$top` and `$skip`. **4. Throttling during bulk fetches** ADP rate limits aggressively. Queue/batch your requests. **5. Complex nested JSON** Prepare to map multi-level objects; flattening the response helps. **6. Environment mismatches** ADP sandbox and production behave differently, test both. **7. Silent permission failures** Sometimes the API returns fewer fields simply because your role doesn’t have access. **FAQs** -------- **1. Why do I need the `roleCode` header?** It determines your access level and controls which data fields ADP exposes. **2. Can I filter the job applications?** Yes. Use `$filter`, `$select`, `$orderby`, and other OData-style parameters. **3. What format does the API return?** All responses are JSON, often with deeply nested structures. **4. Is there a limit on how many applications I can fetch at once?** Yes. Use `$top` for batch size and `$skip` for pagination. **5. How do I handle ADP rate limits?** Implement retries with exponential backoff and stagger API calls. **6. Does ADP provide historical application data?** Only if your org’s data retention settings allow it. **7. How do I debug API errors more effectively?** Check status codes, error objects, and verify your scopes + permissions. **Knit: Faster ADP Workforce Now ATS Integration** -------------------------------------------------- Connecting directly to [ADP Workforce Now ATS API ](/integration/adp-workforce-now-ats/?e4f9ab58_page=3)often becomes a maintenance-heavy project, OAuth rotation, permission handling, schema changes, and rate limits add real engineering drag.
