[JazzHR’s ATS API](https://developers.getknit.dev/docs/jazzhr-ats-usecases) gives you exactly that, candidate records, job-linked applications, and metadata developers rely on for downstream automation. This guide breaks down how to fetch job application data from the JazzHR ATS API in a clean, developer-first way. It’s part of our broader deep-dive series on JazzHR integrations, covering authentication, rate limits, sync patterns, and more. For the full ATS API guide, visit [here](/blog/ats-integration-guide/). **Prerequisites** ----------------- - JazzHR account with API access enabled - Valid API key - Python environment with `requests` installed **Key API Endpoints** --------------------- - Get a single candidate: `GET /candidates/{candidate_id}` - Get all candidates: `GET /candidates` **Step-by-Step Guide** ---------------------- ### **1. Set Up Your Environment** ``` import requests ``` ### **2. Define Your API Key** ``` api_key = "your_api_key_here" ``` ### **3. Fetch a Single Candidate** ``` def get_single_candidate(candidate_id): url = f"https://api.jazzhr.com/v1/candidates/{candidate_id}" headers = {"Authorization": f"Bearer {api_key}"} response = requests.get(url, headers=headers) return response.json() ``` ### **4. Fetch All Candidates** ``` def get_all_candidates(): url = "https://api.jazzhr.com/v1/candidates" headers = {"Authorization": f"Bearer {api_key}"} response = requests.get(url, headers=headers) return response.json() ``` **Pitfalls to Watch Out For** ----------------------------- Teams often underestimate the operational friction in production-grade ATS integrations. Keep an eye on: - **Silent auth failures** when tokens are outdated or misconfigured - **Rate limit throttling**, especially when bulk-pulling candidate lists - **Incomplete pagination handling**, leading to missing candidates - **Large payload overhead**, which can slow down downstream systems - **Field variability across candidates**, making schema mapping tricky - **Deprecated endpoints**, particularly in older JazzHR accounts - **Data privacy obligations**, especially around PII and storage locations **FAQs** -------- **How do I get my JazzHR API key?** From your JazzHR admin console or via JazzHR support. **Can I filter candidates by job or status?** Yes. Use query parameters such as job ID, stage, and date filters. **Does JazzHR support pagination?** Yes. Use the pagination parameters to iterate through large datasets. **Is there a sandbox environment?** JazzHR may provide controlled access, confirm with their support team. **What format does the API return?** JSON is the standard response format. **Can I update candidate records via API?** JazzHR exposes PUT/POST endpoints for updates when permitted by your plan. **What should I do if I hit rate limits?** Implement retry logic with backoff or shift to periodic syncs rather than real-time pulls. **How Knit Simplifies JazzHR API Integration** ---------------------------------------------- If your engineering team is tired of managing [JazzHR ATS API ](/integration/jazzhr-ats/)authentication, token handling, endpoint maintenance, and candidate sync logic, Knit takes the heavy lifting out of the equation. A single integration with Knit gives you streamlined, ready-to-consume JazzHR data pipelines, no ongoing maintenance, no breaking changes, and no integration debt piling up. --- **Ready to build this integration?** Explore Knit’s [JazzHR ATS integration](/integration/jazzhr-ats/) or read more about our [Unified ATS API](/integration-categories/unified-ats-api/). ![](https://storage.googleapis.com/knit-website-media/2026/08/64c34ca1e0546a9d333bb35a_Kunal-3-150x150.png)Written by Kunal Mishra Changing integration landscape, one organization at a time‍ Keep Reading ------------ ![](https://storage.googleapis.com/knit-website-media/2026/08/blog-banner-yellow-scaled-640x400.png) [API Directory](https://lb.getknit.dev/blogs/api-directory/) ### [JazzHR ATS API Directory](https://lb.getknit.dev/blog/jazzhr-ats-api-directory/) JazzHR ATS API integration guide covering endpoints, use cases, highlights, and FAQs.
