I want Employment Hero talking seamlessly to our current HR management system so that staff information stays consistent everywhere. The scope covers three core workflows: employee onboarding, performance reviews, and leave management. Data from each of these modules needs to flow in real time, not on a scheduled batch, so webhooks or an always-on API connection will be essential. My HR platform already exposes REST endpoints and supports OAuth2. Employment Hero provides an open API as well, so the task is mainly about mapping fields, building the middleware (or configuring Zapier/Make if you feel it’s quicker), and validating that the sync runs bi-directionally without conflicts or duplicate records. Deliverables • Field-mapping document for all three modules • Working integration code or no-code workflow with clear deployment steps • End-to-end test cases proving real-time sync, including create, update, and delete events • Brief handover notes so my internal admin can monitor or extend the connection later I can supply API keys, sandbox credentials, and sample data as soon as we start.

Hi, This project is a great fit for our team. We have extensive experience building API integrations, middleware platforms, workflow automation, and real-time synchronization systems between business applications. Based on your requirements, I would approach the integration by first defining a clear field-mapping strategy and synchronization model across the three key workflows: ✓ Employee Onboarding ✓ Performance Reviews ✓ Leave Management The solution would include: ✓ OAuth2 authentication ✓ Real-time webhook processing ✓ Bi-directional synchronization ✓ Conflict and duplicate prevention ✓ Audit logging and error handling ✓ Middleware implementation (or Zapier/Make evaluation where appropriate) ✓ End-to-end testing for create, update, and delete events ✓ Deployment and handover documentation Our experience includes HR systems, SaaS integrations, workflow automation, API development, and enterprise data synchronization projects where data consistency and reliability are critical. One important question: If employee records are updated simultaneously in both systems, which platform should be treated as the source of truth, and do both systems already share a common unique employee identifier? I can start with the field-mapping and architecture review immediately and then move into implementation and testing. Best regards, Microlent Team

Hi — Elias here from Miami. I see you're looking to integrate Employment Hero with your current HR management system. This can be a smooth process, but I understand there are a few potential pitfalls, like ensuring data sync is accurate and maintaining user permissions correctly. Often, projects like this can run into issues with API authentication and handling data formats between the two systems. My approach would be to first map out the data flow clearly, then establish a robust connection using OAuth for secure API access. To get started, I’d like to ask: what specific data do you need to sync between the systems? Also, do you have a timeline for when you’d like this integration to be completed? Looking forward to your response.

Interesting project, I will build the bi-directional middleware connecting Employment Hero to your HR platform — covering onboarding, performance reviews, and leave management with real-time webhook listeners for create, update, and delete events. For conflict resolution, I will implement a last-write-wins strategy with timestamp comparison and a dead-letter queue for failed syncs — so no records are silently lost or duplicated. Questions: 1) Which HR platform are you using on the other side? 2) Do you prefer custom middleware or a Zapier/Make approach? This bid is an initial estimate — I will confirm the final cost and timeline once we have walked through the complete requirements together. Ready to start whenever you are. Kamran

Hi, I can build a secure bi-directional integration between Employment Hero and your existing HR system with real-time sync via webhooks and OAuth2 APIs. I’ve already developed similar HR integrations syncing employee lifecycle, leave, and performance data across multiple platforms. Development Approach: API mapping for onboarding, performance, leave - build middleware (Node.js) or configure Make/Zapier if faster - webhook listeners with retry queue - bi-directional sync with deduplication & conflict rules - automated test cases for create/update/delete flows - deployment with logging & monitoring. I’ll also deliver complete field-mapping documentation, working integration code or no-code workflows, end-to-end test cases, and clear handover notes so your admin team can manage or extend it easily. Questions: Which system should act as the source of truth for each module (HRMS or Employment Hero)? Do you need true real-time sync (seconds) or is sub-minute latency acceptable? Thanks

Hello, I can see the real risk here isn’t just syncing data , it’s preventing silent drift between systems when onboarding, reviews, or leave updates happen in different places. That’s exactly the kind of integration I’ve handled before with REST APIs, OAuth2, webhook-driven syncs, and conflict-safe field mapping. I’d approach this by first mapping the three modules end-to-end, then building the middleware or a Make/Zapier flow where it’s genuinely the faster fit, and finally validating bi-directional sync with create, update, and delete tests so duplicates don’t creep in. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. If you’d like, I can start by reviewing your API auth flow, webhook support, and the field structure for onboarding/performance/leave so we choose the cleanest path together. Does Employment Hero expose webhooks for all three modules, or should I design a polling fallback for any event types? Best regards, Asad

Hi, I can help build a reliable, real-time integration between Employment Hero and your existing HR management system, ensuring employee onboarding, performance reviews, and leave management data remain synchronized across both platforms. With experience in API integrations, OAuth2 authentication, webhook-based architectures, and automation platforms like Make and Zapier, I can design a bi-directional sync that prevents duplicate records, handles update conflicts, and provides clear monitoring and deployment documentation. A few questions:- 1. What HR management system are you currently using, and does it support outbound webhooks in addition to REST APIs? 2. Which platform should act as the source of truth when conflicting updates occur simultaneously in both systems? 3. Are there any custom employee fields, approval workflows, or organizational structures that must be synchronized beyond the standard employee profile data? I would be happy to review the API documentation and recommend whether a custom middleware solution or a Make/Zapier implementation would be the most reliable and cost-effective approach. Best regards, Nikhil...

Hi I can build a real-time integration between Employment Hero and your existing HR management system so employee onboarding, performance reviews, and leave management stay synchronized across both platforms. I have experience with REST APIs, OAuth2, webhook-driven workflows, middleware development, field mapping, error handling, duplicate prevention, and bi-directional data sync. The main technical challenge is avoiding conflicts when the same employee record is created, updated, or deleted from either system. My solution would be to create a clear field-mapping document, define source-of-truth rules, build webhook/API logic, and add validation so records sync cleanly without duplicates. I can also implement logging, retry handling, and conflict detection so your internal admin can monitor the integration after handover. Depending on the complexity of each module, I can recommend either custom middleware or a faster Zapier/Make workflow where it fits reliably. The final delivery would include working sync flows, deployment steps, end-to-end test cases, and handover notes for future maintenance. Thanks, Hercules
